"see the world as it is not as you want it to be"

I see it's 3:1 UCI compliant. Seems weird if it's truly a new bar. Is that 3:1 shape still a rule?

Yes, applies to everything other than the frame (which can be 3.2:1)
UCI have no intention of lifting it for the bars.

unless they fixed the ridiculously-easy-to-strip-2mm-bolts that control the extension fore-aft adjustment, I wouldn't go near them. On the flip side, the adjustability of the pads looks nice...

They have these cool things called torque wrenches nowadays. Just sayin'...

Seems very well thought out.

torque wrench or no, the heads of those things strip if you look at them funny. It's a known flaw that vision warrantied out for me, but a hassle nonetheless.

I saw this bar yesterday and thought it looked attractive especially for the price. I'm at a toss up between the Alpha X and now this bar. I wonder how the stem will integrate with the Felt IA 10 frame?

that looks pretty sweet and the price point is excellent

Thanks for the support Brian! We worked hard on this design and are pretty proud of it.

Thanks for the feedback. Vision's new Metron bar system uses only M5 clamping bolts for the extensions. We appreciate your support! Happy riding.

Good on ya then. With that and the new cups, this looks like a great option.

Nice looking bar. I really like that you can rotate the pads inward. Just a couple of friendly suggestions for future products:

• Please make the grip extensions on the base bar longer. Profile Design finally got this right with their Aeria Ultimate. People with larger hands (such as myself) really have a hard time getting a grip on the base bar.
• Something I'm encouraging all manufacturers to move towards are Torx bolts. It's just a better interface IMO.

Side question about another product: do you guys have any intention of making your tri spoke wheel in a disc brake configuration? IMO, tri spokes will be one of the better wheel choices for disc brake TT bikes as the move from 18 to 24 spokes for disc brakes results in a non-trivial increase in aerodynamic drag.

edit: one more question. Any intention to offer your NS modular aero crankset with 1x chainrings? Or will standard 130/110 chainrings work with it? Thanks.

GreenPlease, we appreciate all your insight. Our design team has seen your suggestions and will take them into consideration for future creations. We are aware of the heavy focus to move in the direction of disc brakes in all road disciplines. For the 2019 line-up, Vision has updated the 3-spoke wheel for improved aerodynamics, as well as offering a clincher and tubular disc brake option. As for the new aero modular crankset, we've got you covered on that too! You may simply remove the spider and fairing and install the direct mount MegaTooth 1X ring of your choice. Thanks for paying such close attention to our up and coming products.

How will this fit on an IA-10?

---

"see the world as it is not as you want it to be"

TizzleDK and Miprzybelski, good question! From what we can tell on the AI-10 frame, the standard 1 1/8" steer tube and the interface for the new Metron bar appear to be compatible. Happy building!

When will this be available to purchase in online store?

I watched the video of the new aerobars. The one missing component seems to be the ability to move the elbows closer together. It would be great if you could add an adapter plate so that the pads could be moved close enough to touch. Narrow is aero

Hard... and also good work - congrats!

Does ist have a hole/stop for a center-pull brake (aka TriRig)? And what is the width of the basebar?

Further question - just so that we all have a good laugh - can we hide the damned Blipbox in there?

Would this be a worthy option for me to finally upgrade the crummy stock 3T Aura Pro on my 2012 Cervelo P2?

We love to see all the interest! Our 'Snakebite' Metron Aero bar will be available in the US starting November. Come see us at Reno Interbike, or Kona IronMan to try out the different positions and learn more about all it can do. Please see adjustability info below. It does not have a stop for center pull brakes. As for the Blip Box, we have not physically tried it, however the compartment that could house the blip box measures:
26mm Width
30mm Depth
50mm usable Length

I’m not sure if you can answer this but are you supplying the cockpit for the next Cannondale Slice and will that cockpit have adjustable tilt?

Grumpier Mike, If you favor a “Narrow is Aero” arm rest position we got you covered….and more importantly no adapter plates are needed! The Metron aerobar arm rest plates are a Asymmetric flip-flop design which can be orientated in 4 different positions to meet a wide range in width and reach. Though the minimum width called out in the spec is 111mm Center to Center (210mm Outside to outside), it is possible for the user to go to an absolute minimum arm rest measurement as low as 96mm Center to Center (195mm outside to outside). In this narrow position there is literally a 2mm of overlap with the arm rest plates but since the plates are composite, the small amount of flex they have at the ends will compress together and work.
For those curious about widths on the other end of the spectrum, the width positions step outward every 15mm to the max which is 261mm Center to center (360 outside to outside).
Please see attached diagrams below.

[quote]Does ist have a hole/stop for a center-pull brake (aka TriRig)?[/quote]

It doesn't really matter. The TriRig brake is at most 1w faster vs Vision's brake in the wind tunnel testing I did head to head at 0, -5, -7.5 & -10 yaw.

Hey Vision-USA

I'd love to get my hands on a set to test in the tunnel/and or field test if you're interested.

Any idea if the new bar/stem would work on a Fuji Norcom Straight (with the stem "slammed", of course)?

TIA!

I'd like a free set for field testing too :)

what would be the equivalent standard stem length and angle for the this system? i see that the min stack for the system is 55mm but it's hard to figure out the overall fit without knowing the stem specitics. thanks

Hi Andrew, Thanks for the interest in the Metron aerobar.
Short answer is: Yes, the Metron aerobar will fit your Fuji Norcom Straight.

Now for the long answer…

Head tube clearance:
In the “Slammed” position the issue is clearance from a bulging head tube. The Fuji head tube does not have this problem because the head tube steps 5mm below the headset interface.
Whereas the underside of the Metron Stem/aerobar is pretty close to horizontal (+0.3mm) from the headset interface.
(So even if you removed the headset top cap, and positioned the stem down on the compression ring in the bearing, you would still have enough clearance for the Metron)


Top Tube Recess/ Rear Stem Clearance:
Knowing the stem interface on a TT bikes was going to be tight with different top tube recess diameters, we did our best to snug the rear portion of the Metron stem as close to the steer tube as possible.
On the Norcom Straight, the top tube recess at the stem has a ф52mm dia. which = a 11.7mm clearance from the steer tube.
For the Metron stem, it has a Apex width of 10.4mm from the steer tube which= 1.8mm clearance from fillet.
So though it will be visually tight, the clearance is there so you are good to go.

See diagrams attached below. Cheers!.

Hi Jazzymusicman, the Metron Aerobar Stem length is 90mm and the angle is a (-) 17.5deg.
If you are looking for more details, please see our reply to Andrew Coggan and the illustrations provided.
Happy riding!

Thank you very much for your answer, especially the dimensional details. Your new bar would seem like an excellent choice to replace the Oval stem and bar that come with the Norcom Straight, which really hold back an otherwise very good bike.

Hi Vision,

Glad to see you on Slowtwitch. Can you comment on how the bar would fit an Orbea Ordu OMP model? Are there cable exit holes at the top of the stem (instead of back)?

Hi Vision USA,
Question for you... You indicated this in an earlier response, " For the 2019 line-up, Vision has updated the 3-spoke wheel for improved aerodynamics, as well as offering a clincher and tubular disc brake option."
Can you please elaborate on the aero differences from 2017 to 2019? Also, what will the width be for 2019?
Thanks,

Team Zoot-Texas, and Pickle Juice

More of a reply to Vision, I'm also curious about the width.

Bloodyshogun, pleasure is ours. Our cable exits come out the back of the stem. The rear brake cable could be tight due to the routing on the top tube, but the shift cables and front brake cable path should have no issues. Please see attached photo for a better visual.

They needed a torx bit to get them to adjust. Much easier than Allen key.

Not 100% sure, but Ordu models for 2019 seem to be using this aerobar. The rear brake cable is routed under the bar and not through the stem: https://www.orbea.com/...les/ordu-m10-team-19.

Stem cabling is understood, but how do you route the front-brake cable? Not through the stem but through the basebar I suppose?! Could you please clarify?

One suggestion about the little bridge: you might consider designing a second version that extends to the front and has mounting options for BTA, headunits etc. Or maybe design a T-shaped part that can be clipped on the bridge and extensions.

Hi TAUGEN,
The 2017 Vision 3-SPK (let’s call “V1”) was developed for a world tour TT specialist back in 2010. It is optimized for a rider who can maintain a higher average speed (27mph/43.5kph + ), AND/OR a Track athlete who rides in an environment that stays within a shallower YAW angle. (0-7.5deg)

Though the V1 3-SPK has had plenty of success and aerodynamics are great for its intended purpose, it is not an ideal wheel choice for the athletes who cannot maintain a higher speed and OR handling skills are not up to par when the wind kicked up due to the increased surface area.

Other tangible limits with the V1 3-SPK design can be;
- Weight= 894gr front tubular.
- Aerodynamically ideal for a 19-23mm tire with rim dimension= 60mmH x 23mmW.
- Tubular only- no clincher

Also, (not that this matters for Tri but interesting tid-bit nonetheless), a UK TT rule was implemented over the years that affected the use of the V1 in competition. (https://www.cyclingtimetrials.org.uk/articles/view/11 article 14-g) Those larger spoke blades and rim depth take up some real estate and with that the V1 is not legal to use in UK TT’s. So improving on the V1, the 2019 3-SPK ( let’s call “V2”) was to stick to the ethos of being a specialty wheel but be more versatile in purpose and function. The primary improvements that V2 has over the V1 is; improved handling in crosswinds, reduced drag in a wider range of YAW angles and lower weight to make a possible option for hilly TT’s.

For instance:
- Reduced Side load and steer torque input;
Compared to the V1, The V2 had a reduction in Side Force by 11% (avg) and a reduction in the steer torque input by 29% (avg).
The Side Force reduction is primarily from the spoke chord length and rim height being shortened but the improvement in steer torque is a direct result from the rim which is derived from our Metron 55.

- Less drag in wider range of YAW;
Reducing the drag on the V2 3SPK was a secondary objective but did manage to drop few watts and widened the ideal YAW range in the process.
The end result was the V2 tubular averaged (-) 2W less in drag from 0-15deg than the V1 tubular.
Since there is no V1 3-SPK clincher, the comparison in drag improvement is a bit apples to oranges (due to tires/rim interface), but the V2 Clincher averaged (-) 7W less drag than the V1 Tubular from 0-15deg YAW.



- Reduced weight;
V2 3-SPK Front tubular=now 720gr, 830gr clincher. (current in hand weight)

- Clincher-Tubeless ready;
18mm hook width

To Note: The rim width measurements on the V2 3-SPK are 55H x 26.5W (tubular) 55H x 26.75W (clincher) which is optimized for a using a 23-25mm tire.
A 23-25mm tire ends up around 24-27.5mm tire widths (depending on brand and model) when installed on the 18mm hook.
Also, …with the spokes and rim using up less internal real estate the 2019 3-SPk is fully legal for the UK TT’s.
As the 2019 gets closer and the 3-SPKs are ready to deliver we plan to release more data….until then stay tuned!

Vision-USA,
Thank you for the detailed explanation. Exactly what I wanted to know. I will wait for the 2019 wheels to come out.
Can you tell me what model or year this wheel is??

https://goo.gl/images/TexdeZ

Thank you.

I'm not looking to field test the bars, but I would like the most cost effective option to get a set onto my fit bike. These look really sweet!

I already have access to dealer cost, so if that is the suggested route, let me know. I am however, not a dealer, and it seems on the fit bikes of competent fitters would be a GREAT location for some demo models.

Taugen, The above link is a counterfeited wheel. While imitation is flattery, this is a very unsafe channel to resource high end components. We always recommend that you shop at authorized retailers. Please think locally when resourcing your product too, there are many helpful and knowledgeable retailers out there. Please shop responsibly!

Vision-USA,

I had a feeling that wheel was not genuine. Fear not, as I do not own that wheel. I merely found a picture of it when searching various tri-spoke wheels.

Thanks,

Team Zoot-Texas, and Pickle Juice

Facepalm.

Could you please tell us where the front-brake cable exits?

Do you consider offering a BTA-Bridge option?

Blabelzabel,

You can view the cable routing from the diagram given to Bloodyshogun on July 30th.

There are two options for cable routing for the front brake:

1. Out the back of the stem
2. A port under the base bar/stem junction.

As for the BTA bridge, we have been working on creating an elegant solution for an aftermarket option. More to come on that at a later date.

Can you say whether the TFA, or at least the pedestal hardware, will fit on the new (2019) Merida Warp TT?
Obviously not a bike that is going to be in your territory but it's no use trying to get info out of Merida.

Cyclenutnz, The 2019 Merida Time Warp has an integrated bar system that uses our SI012 extensions and hardware. Since the pedestal widths are different between the SI012 and the Metron bar, the hardware for the new Metron Bar system will not work. We hope to see the integration with the new Metron bar on models moving forward.

That's what I thought. But, you know, hope springs eternal. The new bar looks really good.
Is there a tilt kit for SI012?

Thanks for the info.

Cyclenutnz, there is no tilt kit for the SI012. Thank you for your support on the new design.

Hey Vision, this bar looks great! I love that the basebar can be flipped and that there is a center-pull cable exit.

I have a couple questions/requests:
1. Would/will you consider making a clamp kit like TriRig's "slammed clamps" to align the extensions with the basebar like your old TFA bar? I'm currently on a 58cm P5-3 with Ventus II bar as long (120mm effective stem) and low as it goes: no steer tube or pad spacers, ~65mm stack from aerobar. I'd like to try getting lower without giving up adjustability for future fit/frame changes.

2. Is your bar fully compatible with the P5 and SuperSlice? By "fully" I'm wondering whether the front brake cable clears for center-pull exit and rear brake can be routed out the back of the stem. SuperSlice seems to be one of a few frames that is lower and longer than my P5.

Thanks!

Can you tell me if the TFA will work on the Ventum One? Looking to build one up and your cockpit seems like a great option for me since I need a particularly wide setup and like that they seem to be able to tilt up easily.

Cheers!

Hi Withrow,
Yes you should be able to switch out the Ventum bar for the Metron Aerobar.
The Ventum One uses a standard 1 1/8 steerer with rear brake cable exiting the top of the stem and into the top tube. The front brake cable goes down the front of the headtube and is hidden with the fairing.
All said the Metron aerobar is designed with the option of running the cables in the same configuration.

Additional info;
The Ventum one fairing is made of a flexible plastic (like a car bumper). From what we understand, It does not use the stem for support and the user cuts the fairing to length to match the underside of the stem.
Furthermore, though the Metron aerobar can store the 5prt Di2 junction box/cables internally (Stem-base bar), The Ventum One's fairing has enough room to run the 5 port junction box/cables and front brake cable if the user so decided.

I can verify what Mark just posted about Ventum.

But. if your stem can fit the di2 control box I found it worked better as the junction box under the ventum cover did run on my head tube.so being hidden inside the aerobar is a much better design.

Your fork cover attaches directly to the fork. With the ventum aerobar it tucks in under and into the shape of the carbon stem. But is not required. I tested my culprit stuff on a Ventum and just had to cut the cover to the right length and appropriate angle to match. It came out nice when cut properly.

So, the new Metron should be a great new addition to a Ventum.

Thanks for your help guys, that sounds awesome!

BigBoyND, sorry for the delay in response. We took some time to be as thorough as we could.

The “slammed arm rest plates with the extensions under the base bar” position was something we heavily considered during the design phases for the Metron. In the end the added cost/weight and limited adjustability of the additional configurations for the arm rest plates in those low stack positions would have pushed the project out of the target goals we had set. That isn’t to say we are giving up on this idea for the future, just that for this version we could not find a workable solution to what you propose.

2. Is your bar fully compatible with the P5 and SuperSlice? By "fully" I'm wondering whether the front brake cable clears for center-pull exit and rear brake can be routed out the back of the stem. SuperSlice seems to be one of a few frames that is lower and longer than my P5.

P5:
The Metron aero bar is fully compatible with installing on your P53 and should be no issue. The key point is that you have enough steer tube exposed from the top cap of the headset (29mm minimum is needed) to clamp the Metron aerobar on the fork. As for the cable routing the Metron aerobar has many options for routing the front/rear cable paths with exhaust ports coming out the back and underside of the bar/stem. Your bike, you choose.
Super Slice Disc TT;
The feasibility to change out Cannondale’s integrated bar would have to be worked out with the dealer and depending on how cannondale sells them from the factory might be a hassle for both parties.
Can it be done? Sure, but there are a few hoops one would have to jump through with a dealer to change it out and make it possible.
Back to that minimum 29mm steer tube clamp surface…You will need a uncut fork-steer tube from the factory. (This is assuming the SS forks are pre-cut for each size and they ship as is.) The SS integrated stem has a shallow height clamp (27.5mm) with a minimum surface of 26.5mm needed on their 1-1/8th steer tube. Now 2.5mm of steer clamp surface area might not sound like a lot to some, but to us that is the difference between having a secure component or making a unexpected trip to the ER. So IF (this is a big IF) one could get a new uncut fork from Cannondale for the Super Slice from the factory, the dealer/mechanic could then cut the steer tube properly to fit the Metron Aerobar and it could work. The Metron stem steering clearance is within the same dimensions as Cannondale’s so you would have no rotating interference with the integrated cable fairing that is mounted between the stem and top tube.
The second hoop involves the integrated cable fairing that routes the cables at the back of the stem into the Top tube. Considering the Metron Stem cable exhaust ports will be 3mm taller in stack than Cannondale’s, this cover could possibly need a slight modification (or removed) to ensure good cable flow from the stem into the frame. All said, we have to state that any modification to the frame or frame components could also void any warranty with Cannondale.
So to conclude; if you are thinking about buying a Super Slice TT, please call and or talk to your local Cannondale dealer before purchasing about any changes you would like to do (and if they are possible) before going down that rabbit hole.

Thanks for the interest, hope this helps!

Thank you for the thorough response!

I saw in this thread someone mentioning that the lowest possible stack was 55mm but I see on your site that it’s 70? Which one is right.
Also I see you said that it doesn’t have a center hole for a brake but also someone else sated it did. I’m sure you are obviously the correct answer but I wanted to check.

Also does anyone have these bars and have any details or pictures to share?

2019 T-Rex Tri Series

better than TriRigs orange accents and logo

The hardware accents were originally orange, but have been all black for almost two years. And the logos are dark grey. Omni also changed to a monochromatic color scheme. We listen :-)

If you look at any recent builds with Alpha X or Alpha One on this forum, you’ll see the black hardware. It’s very slick and stealthy.

i love the black hardware on my x bar/stem setup...not so much the orange accents around the brake levers or the TriRig decal under the clearcoat. but it's OK, i tape it over with my nutrition schedule ;)

Has anyone installed this on a shiv?

I'm hoping to. I want some more clear info if I can get it. found a good deal on these on ebay yesterday and went to buy them today and they were gone. Should have did it yesterday.

2019 T-Rex Tri Series

Hi all,

Got a package with the TFA Aeroabar and I'm really impressed. So far I used a 3T Brezza II LTD aerobar, but the TFA looks even more filigree and I will be able to realize a better cable routing. At the moment I'm thinking about how to integrate my SRAM blipbox, but I allready have some ideas.

Before I start assembling, I have one more question regarding cutting my fork and mounting the expander into it.
The stem clamping area is 29.85mm high. The expander requires 2.05mm and the red top cap addtional 1.25mm.
If I now assume that there is no gap between expander and red cap, then I still have 26.55mm "real clamping area".
But my expectation is that I need a small gap to realize a preload to the stem.
Is this right?

What is your recommendation?
Do you have a cut through picture to explain this situation?

Thanks in advance.

Jan

Sorry, I made a mistake, the expander is housed completely in the fork. In this case I will have enough clamping surface to mount the stem.

Sorry, I still don't get it.

I thought the expander will disappear in the fork, but checked again and the upper cap of the expander will stay on top of the fork.

Hope you can give me an advice how to cut the fork and to mount the stem.

I am a little bit confused, because you attached a compressor manual to the TFA, that doesn't take the included expander (TH-863-1) into account.
Also the drawing in the manual is showing another compressor as that is in the package.

Thanks Jan

Vision-USA,

I thought these bars wouldn't quite work for me, but the found a lot of conflicting information on fit. Would you mind clarifying?

1. What's the actual Pad X range on these bars? I see:

a. Official website: Stating it's -9 to -99. Assuming base bar is a 90mm stem equivalent. This would put Pad X (to rear of pad at -9 to 81mm)
https://shop.visiontechusa.com/.../p/specs_table_1.jpg

b. Slowtwitch's article shows Pad X to rear of pad at -15mm to 75mm
https://www.slowtwitch.com/...ron-tfa_top_pads.png

c. At various retailers, I see a Pad X chart showing 45 to 135mm Pad X. Are these to Pad Center? So assuming the pads are around 100mm in length?
https://www.wizbiker.com/...-bar-5-1000x1000.jpg

2. Question regarding DI2 routing. How does it work?

a. Orbea's Ordu shows DI2 cable coming out of the extensions going to the stem from the back cavity, then another DI2 cable coming out from the bottom of the basebar (heatshrunk with brake cable) entering frame
https://www.orbea.com/...DE-ORDU_M10iTEAM.jpg

b. TriRig's photo of Starky shows DI2 cable coming down from the front of the bar (with the help of electric tape) into the basebar from under, then entering frame from the back (presumeably Starky took a dremel to his frame)
https://www.tririg.com/...70_3_Race_Day_89.jpg

c. From picture below, there appears to be a hole in a groove next to the extension risers. Are these for DI2 cables to enter the basebar? I assumed so, until I saw that neither Orbea's Ordu pictures or Starky's pictures appear to use them.
https://www.duckingtiger.com/...view-12-620x620.jpeg

Curious if anyone has used this bar with a Dimond Marquise and if so could share some images of the installation.

Thanks!

Vision, Would you happen to have a cable routing diagram for this aerobar? I picked up one for my tri bike the other day and would like to run the cables the correct way instead of guessing. I will be running a mechanical drivetrain as well if that makes any difference. Thank you

We unforutantly do not have a cable routing diagram for the TFA bar. The bar has several cable routing options that should be able to work with just about any set up you have.

Please let me know if you have any questions.

Kevin

Hi, I'm looking at putting these bars onto a cervelo p series but also route the front brake cable through the steerer tube as a few people have managed to do on the p series thread.

Does anyone know if there is room to run a hydraulic front brake hose through the stem on these and down through the steerer using the acr expander?

Thanks
Andy

We would not recommend this. The bend required in the brake hose in order to route the hose between the top cover of the stem and the steer tube would most likely damage the hose and prevent the brake from working correctly. This bar system is not designed to be used with the ACR system and does not have additional space above the top of the steer tube to allow cable to fit. The ACR compression plug will also not allow you to use the bolt needed to hold the TFA top cover on the bar.

Kevin

Ah that's a real shame. Is there any other separate stem set up of Vision's that might work with the trimax bars?

Ideally it would still enable me me to route the other cables out the back of the stem

Otherwise i guess it's keeping the front brake external

Thanks for responding anyway

I looked at the diagrams online and it appears that these extensions are compatible with the Argon E-119, I probably should have asked that earlier! Are they compatible with the current base plate and would just be plug and play?

---

Washed up footy player turned Triathlete.

The TFE extensions are not compatible with the base bar on an Argon 18. At this time we do not have an adapter to allow them to fit. Our speed extension will fit any standard 22.2 extension mounts.

Yes, the ACR stems

Congrats on the TDF TT win with your TFE extensions! What is needed to put them on the Cervelo P5 disc? I’m assuming the EX10 tilt conversion kit was used? Anything else needed to put them on the P5 disc?

Those were full custom, all you need to put them on a P5D is to give lots of money to speedbar/carbonwasp etc
(Vision not offering custom setups to the public as far as I know)

At this time we do not have a solution available to mount the TFE's to a Cervelo base bar. Those were custom extension and adapters.

Kevin

Hi Kevin, i have an old speedconcept 7.0 from 2014, can i upgrade the basic cockpit with the Metron TFA? thnx

I believe your bike has a Trek specific stem that can not be replaced. If you are able to email me clear pictures of your handlebar/ stem combo I can confirm. Kevin@fullspeedahead.com

what you have with that bike is a stem that is specific to that bike, and cannot be swapped for another. on that stem goes the base bar. on the base bar goes the pedestal. on the pedestal goes the monoextension. all these parts are congruent with each other, but not with anything else. in my imagination i can't see how any other front end will work on that bike, but it's possible there's something i don't see.

Dan Empfield
aka Slowman

Looks like a fairly standard stem on the 7.0. https://archive.trekbikes.com/..._concept_7_0/details. The 7.5 has a unique stem. https://archive.trekbikes.com/..._concept_7_5/details

ah. sorry. in my head was the carbon superbike speed concept. carry on.

---

Dan Empfield
aka Slowman

Also interested in the answer for the trek speed concept. I have a 2016 7.0. The statement above is correct in that it comes with a standard 1 1/8” stem. All the cables (front brake excluded) are router through the frame behind the stem. So just a matter of stem clearance?

I have a 2016 Felt IA FRD. Will the TFA work this frame? Clearance looks like it might be close.

You would be better off with the Si013 bar which uses a standard 31.8 clamping surface and the IA stem from Felt. The TFA will not have a mount point for your IA nose cone and you would need to modify the nose cone to fit the TFA stem body and to mount the nose cone.

@Kevin - I just got a QR X-PR. From the looks of it, I should be able to fit the TFA basebar into the X-PR (I think it is used on the higher end model, V-PR). Or am I mistaken with this assumption.
Also, does Vision Tech sell the pieces/parts that would let me use the Profile Design Aeria from hydration with the TFA.

The part you're after is an adaptor made by QR to fit the HSF clip on to the snakebite stem. You would need to ask QR customer service whether you can purchase it.
X-PR and V-PR are the same frame, so can use the same bars.

Yup, reached out to QR. Unfortunately they don't sell that adaptor as an aftermarket piece or a spare part.
It only comes with the V-PR when you purchase the bike with the Aeria HSF hydration.

Any updates on a BTA mounting solution for these aerobars?

Our Metron front hydration system has an adapter that replaces a spacer on the TFA or Si013. This is adapter also works with our Metron hydration extension mount and would allow you to mount a standard bottle cage. If that is not what you are looking for please provide specific details and I can forward them on to our development team.

Metron Hydration extension mount

That's exactly what I was looking for. So you can either mount this onto the extensions or use it in conjunction with these to mount a standard bottle cage BTA.

That will fit any round extension. If you have a TFA or Si013 bar that adapter will take the place of a 5mm spacer and replace the extension mounting point.

I'm thinking of using these on a 2022 Merida Timewarp Tri disc, in order to drop the pad stack, but it's not clear to me that it will fit, without the underside of the stem hitting the front of the headtube. Any way I can figure this out/this can be confirmed, Kevin?

The TFA will not fit. The Merida Timewarp uses a custom base bar.

Has anyone ever installed this setup on a Cervelo P5-6 and replacing the 3T Aura base bar with this? I'm curious on routing the rear hydraulic brake cable that goes through the Aura base bar and also covers the hole in the frame. Any info appreciated. Thanks.
