New fork for ZIPP 3001
Can't Post
I have just acquired a 1997 ZIPP 3001 and plan to update the frame. Specifically, the noodle stock fork. My choices for a replacement are limited by the 1" headtube, but the Easton EC90 Aero appears to be a very solid fork that comes in a 1" steerer. I believe that the rake is the same for both forks, so the switch should be pretty straight forward.
Good move, bad move, anyone, Bueller?
Thanks

You'll need to switch to a threadless headset first.

Your options are further limited unless you (or the previous owner) have had the headset replaced with a more modern threadless design.
If you have, or will get, a threadless design than the EC90 and the Reynolds Ouzo Aero Pro are both great choices and can be found online/ebay quite often.
If you aren't going to get the headset upgraded you've gotta get REALLY lucky or get a custom fork. Your best custom option is an Aero fork from Argos, they will custom make it for you for about $200.
I like the Argos fork so much that I prefer it over the EC90 or the Reynolds forks... even though I have a threadless headset on my zipp2001. The argos is more aero (from an aspect ratio and frontal area perspective) and the steer tube isn't carbon.
hope this helps

Good move. The original fork is terrible! Best case scenario you find a Lotus fork w/threaded steerer, cheapest option is probably a Giant TCR 1" aero fork from the older road bike range, they'll have enough steerer to play with

If you decide to replace the headset, I've got an Easton EC90 Aero with 214mm of steerer in the classifieds:

It is my understanding that the threaded American Classic headset (TriLock?) can be converted to threadless. Does anyone know where I can get bearings and topcaps for this headset? I tried AmClassic, but they do not have bearings any more. In fact, they don't have the specs for the bearings any longer-I think they were lost in a fire?
In the end, it may be easier to replace the headset entirely. I seem to recall reading that the headset is epoxied into the headtube and can be removed by heating with a hairdryer without harming frame integrity. I assume that a new headset needs to be epoxied in place. Will this require a jig, or are the faces sufficiently square to permit the new headset to align properly without one?
I appreciate your collective expertise.

Not quite enough steer tube for the frame, thanks for the offer though.

You have a super-collector frame. Don't DIY hair-dryer / self epoxy it into place. The new headset needs to be placed correctly (straight) into the frame.
Get a threadless king headset and have someone who has done this before do it for you.

Hey,
Actually the aspect ratio for the Reynolds Carbon Aero is better than the Argos; although the Argos is thinner outright. In terms of finding it on Ebay, in the last year or so, the reynolds has become increasingly difficult to find in the correct rake for most tri bikes (43mm rake); so the Argos might be the way to go...at the very least, you will never have to worry about a buying a bad fork from Ebay; which may or may not have some damage.

I see no problem with your plan. Back in the day I switched from the stock aluminum fork on my 2001 to a Kestrel EMS fork. the shop that I originally bought the frame from erroneously had the headset swapped to a King for me. Well it was a case of the mechanic not knowing when to stop and he removed the bonded in cups anyway. The King headset was loose enough to allow a crack to develop in the headtube. I sent the frame into Zipp and they repaired the tube and bonded the King headset in properly. Never had a problem after that. For such a valuable frame do yourself and it justice and send in to Zipp and get the work done right, you'll be glad you did.

I've had both a 2001 and 3001 and neither of them had loose headset cups or required any new epoxy bonding to keep them in place. Strange.

It can't be done. Bad move. Send it to me and I'll take that piece of junk off your hands. Won't even charge you for it. Go get a real bike, like a Cervelo or something, and I'll be forced to ride that old, slow dinosaur. You really don't want it. Look into my eyes...

Trust me, I could not give this away with a clear conscious. It has a hideous clearcoat over nude carbon, the original ZIPP carbon cranks, some crazy aero brakeset with carbon covers. It's the type of bike only a mother could love, trust me this is not the bike you are looking for-

Send it to Dave Hill who used to work for Zipp & did all of their warranty work up until 2007 when the 10 year frame warranties expired.
Have him put in a Chris King headset.
Have him check out the internal cable runs, plus check to make sure that all of the bolts/washers/mechanicals on the beam are ok; replace anything that is even remotely worn now, as the parts are disappearing fast. Buy xtra bolts for the seat bracket (you WILL need them).
As cool looking as they are, take the carbon brakes off the bike & put them somewhere safe. They don't stop for shit, require quite a bit of maintenance, and are heavy, and are a huge PITA if you are actually going to be riding this bike on a regular basis. Use a DA 7800 or similar brake on the front, and the Oval brake on the rear---it fits perfectly & works great. Or, if you really feel like going old school, buy a DA AX series rear brake on ebay, do some work with a dremel + stainless steel mounting bolt, and you'll be in good shape.
As for forks---personally I hate the Easton, but I'm a big guy. The Oval Aero works great & comes up on ebay occasionally in 1". What I really liked though was a Profile 1" ACD fork, though you may need to do some more dremel work as the fit with some tire/rim combos was tight on mine. Stiff fork. There is also a cheapy Taiwanese aero fork that is readily available on ebay in 1"---nude carbon at the top with a gradual fade to black at the bottom. Very aero though it isn't as stiff as the Oval or the Profile.
These are great bikes (make sure you actually have a 3001, and not a rebadged 2001 w/3001 stickers----if there isn't a plate inside the chainstay w/the build # of the 3001 (they only "officially" made 100 or so of these) and most of the Nude Carbons were warranty replacements built at the end of Zipp's frame building experiment), a bit heavy vs the current models out there, but very comfy & fast.

You bring up a point that has been bugging me: The frame is identical to the version pictured on the cover of the 1996 ZIPP catalog (nude carbon, decals in the clear coat, additional layer of material on sides of downtube visible through clearcoat, carbon fork) but there is no plate inside the non-drive chainstay with a number. The gent that I purchased the frame from got it from the original owner, and indicated that the frame came new directly from ZIPP, and not on a replacement/repair. As far as I can tell, all of the components on the frame are original spec: 8 spd DA, 1st generation ZIPP carbon cranks, AmClassic headset, Profile design aerobars and cowhorns. Is this then a rebranded 2001 directly from the factory?

Is there anything on the inside of the chainstays? It's a big sticker and could well have just come off (or been taken off). I understand that if you can see the industrial strip of boron on the downtube then it's a 3001, no question. I've just replaced the fork on mine, put an old Time carbon aero 1" one on there.

Hi
My (still surviving 2001) Zipp had its sticker bubble and melt after I used the wrong aerosol chainlube. It was not clearcoated in. Call Dave or Andy at Zipp if you have questions. There are not many 3001s so a verification should be possible with good photos.
Cheers

Dave Hill could answer better than I, but no, you don't have an "official" 3001----those had a stainless metal plate on the inside chainstay w/the model #. That doesn't mean that it isn't a Zipp 3001 though---especially in the clear carbon----whether it was a warranty, or a post-official-run build I couldn't tell you. What I can tell you is that it likely doesn't matter one iota, except to a few uber-Zipp geeks/collectors. Whether there was a boron strip or not I couldn't tell you. Whether it changed the ride or not I couldn't tell you, and I've ridden both & can't feel the difference. I've owned both 3001 & 2001 & they are basically identical, especially the later builds of the 2001. I currently own an all-nude 2001, that I don't ride much, and basically everything is the same as the 3001 except for the stickers & paint job. What I do know is that the all-nude Zipps (2001/3001) are MUCH rarer than the fade 3001 or the painted 2001s.
Sounds like you have a very, very cool bike, especially with the original Zipp cranks (been waiting over a year for a set to show on ebay---no luck so far). I'm keeping mine just to hang on the wall, complete with Zipp 3000 tri-spoke wheels, Zipp cranks (when I obtain them), and other carbon goodies.
Back to your original question re fork---this might be a good one to try---all nude carbon & Alpha Q makes good stuff. Probably not as aero as the others I mentioned, but fwiw:

It seems like there should be an asterisk when someone says only 100 ZIPP 3001s were made. I put the bike on a trainer to test position and noticed A LOT of sway in the beam when I pedal. I do have the beam raised quite a bit, but not outside of spec (6 full turns of pivot bolt). While my form is not great, I was shocked to see how much sway I generated. Have you noticed this as well on either of your frames?

You could nearly do origami with the very first edition 2001 frames. My 3001 is pretty stiff though, I don't think it flexes like crazy but I did have that 2001 to compare it against

The beam is going to flex---its the nature of the beast. The BB is very solid, so out-of-seat climbing is as good, or better, than similar TT bikes of that era (and up until recently---today's BB's are finally as big & stiff as the Zipps).
