11 speed Time Trial groupset

I'm a new BR Forum user so please forgive my question (if asked and answered elsewhere but I didn't find...) and my poor English (I'm not a native speaker).

I have some doubts about Campagnolo TT policy. The first question is: why are they so stubbornly refusing to revamp their TT stuff? Brake levers seem to be ages old. No team is using them. Shifters (as far as I am concerned) are OK but will we ever see 11 speed version?? Ghibli wheel is fine. And a question number two: are 10s TT shifters compatible with 11s drivetrains? For Campagnolo technicians the answer is simple:"10s bar ends are not compatible with 11s transmission". But I can clearly see something quite opposite here:

CORRATEC:

BOTTECCHIA:

CIPOLLINI:

PINARELLO:

(just to mention only a few brands!)


So how did these manufacturers overcome the problem (or maybe not such a big deal after all) of 10s shifters + 11s drivetrain???

I would be eternally grateful for an enlightening answer!

    Maybe it's me but why would anyone want 11s on a TT bike?

    Many of my best times were done on a fixed wheel track bike.

    Campag probably thought the same as most TT's are done on relatively flat courses and I bet most people would only use the biggest 4 gears, same as why would anyone want a double on a TT bike when I bet people never ever shift onto the inner ring? :? :roll:

    Yes, I understand the idea of 10s TT perfectly well. And I agree, 10s TT drivetrain is sufficient.

    I was just wandering about the technical possibility of mixing 10s TT shifters with 11s groupset. As you can see by following the links it is possible and apparently quite easy. I think it's just a minor change in one of the shifters (the right one): replacing one small element with another one which enables 11s indexed work.

    By the way, it's interesting to see how much 2008 stuff Campagnolo still have in their stock :-) I say 2008 because the last 10s versions of Chorus and Record (PRO racing groupsets) are from 2008 as far as I remember.

    Technical solutions aside, I believe it's high time Campag revamped their TT range and showed off something more up to date. In terms of aerodynamics (brake levers) and maybe a new TT crankset (look at those marvellous Vision's or SRAM's cranksets. Even aero chainrings). The Ghibli disc wheel and shifters are OK.

    Plenty of courses require people to go into the inner chainring, most people that TT probably do so on more sporting courses, and if they are not as strong as the faster riders they will use the inner chainring on the hills. Even my local course has a inner chainring climb in it for the weaker riders.

    As for using just a few gears, I use 10 gears whilst TT-ing, just so I can get the best cadence for me to get the correct power out, and sometimes have had to use the inner ring on steep hills, or even shallower climbs when extremely tired.

    To the OP, what about using the levers in friction mode, you should be able to get 10sp to work on 11 sp then.

    could be. But I don't suppose those Cipollini, Bottecchia and other TT machines have had friction mode shifters installed.

    I also have a very good quality photo (but I must learn how to upload it here) of a Katusha rider (he's riding Ridley Dean) with 11s TT stuff. This is a real mystery to me... :) I'm going to upload this photo soon so that you can see this.

    Has it occured that they might be using equipment that is not available for end users as yet. Katusha are using electronic Campag, but they are the only team, and it is not available to end users as yet.

    I thought it was only Movistar using electric Campag this year.

    Yes sorry it is Movistar and not Katusha

    It could be that they're using a normal 10 speed bar end shifter - but replacing the inner ratchet with an 11 speed one. I don't think (although I'll check with our Campag guru at work tomorrow) that the ratchets in the ergo's are any different to those in the bar end shifters. But if this is the case, I don't understand why Campag don't have bar end shifters that are commercially available!!
