The XL will be 325mm. These are designed to stop short of the elbow.

Kevin, what are the front hydration options with these extensions. It seems like a standard system, whether it be Vision, Xlab, etc., will not work with these.

The extensions come with a hydration mount for our front hydration system. It replaces a 5mm stack spacer from the Si013 or TFA and mounts to the hinge of the hydration system.

I have a set of the Pro Extensions in size large if anyone is interested. As well as the cervelo P5d adapter to fit them.

If anyone is interested and has enough space. I made up a standard bottle cage holder for fixing to the cross bar section:

I need to find some shorter bolts - but happy with it so far.

I used the Vision front hydration system for a while, looks good, unfortunately it's not that great in practice.

Maybe it works better sat in-between two round extensions as it would be a bit more solid, but mounted on the sandwiched pylons it bounces around way too much.

OK on a smooth road surface, but anything less and you'll be wearing whatever is in the bottle. I made an extra piece to hold down the filler flap that kept popping open, that just moved the problem to fluid coming out around the straw hole instead, not great considering it cost the best part of £100.

The TFE extensions are great though.

Doesn't move at all between two normal pole extensions. I had been wanting the specific mount for it, but I'll stay away from that now! Thank!

I found the refill thing awful, should of gone with a one way rubber value.

I prefer to keep it simple now with just a bottle after finding the system fiddly, surprised Vision don't make something like I made up (although I'm sure much slicker and lighter..)

Does the XL exist yet? I can only see the three sizes and measuring myself I think I'll be almost perfect for an XL.
Thanks!

They are in production but not in stock.

Thanks - do you have any predictions on when we might be able to order? I'm hoping to have a QR V-PR built up over the winter.

We already have a large amount on backorder. I would suggest you call our sales team at 425-488-8653 and get a set on backorder. They should also be able to give you an ETA.

Does someone has the dimensions for the px adapter?

Do you have a specific dimension you are looking for? or a question about the adapter?

The adapter. Maybe I can use it for a other brand extension to fit on my p3x

So you are looking for the bolt spacing on the adapter and not dimensions of the adapter. The bolt spacing is 8mm center to center and 3x6 hole pattern.

Yes and also the overal with outside and inside

Outside I assume you are asking for overall width but please clarify what you mean by inside.

I mean this dimensions

Yup. Very happy with it.

I try and design and print my own things, but this is very well made and something I couldn’t do.

Get one. Worth it

Thanks 👍👍

I show they are expected around November. Be aware we already have a large amount of that shipment reserved under back orders. I would recommend calling 425-488-8653 and placing a backorder.
