i have an 2012 record group, and occasionally, my right side thumb shifter will freeze. it won't budge at all. shifting up a gear with the paddle seems to free it and then i can resume shifting the rear derailleur down the gears again with the thumb shifter.

anyone familiar with this issue?

Are you by accident pushing in the other shift lever? If that is moved in even slightly it blocks the action of the thumb shifter.

i can't imagine that i am. i've been on campagnolo for the past 6 years and this has never happened before.

I have the exact same issue as you do on a 2012 Chorus group. Every so often, the right thumb shifter will not budge. Shifting to a larger cog on the cassette will free it up. I have not yet figured out what the issue is, so I'm pretty much no help to you other than letting you know that you're not the only one.

google seems to be of no help either. i've had 2 mechanic look at it with no results.

I'm with Miller. If the other lever is even minutely pressed, or hung up after the previous shift, the thumb leverwill not move.

I have a 2012 SR which does the same thing all the time.

Sorry I can't be much help. I have had it checked by my LBS and they only say what has been said....which isn't much help, I guess.

I had 2011 SR (11 speed) & 2008-09 Record (10 speed) with out ever having a problem.

All I can do is shift in the opposite direction and it fixes itself.......it's a bit frustrating.

You could have your LBS send it it under warrentee, but Campagnolo may not see the problem.
Your not alone.

I have double-checked and re-checked to see if I am putting any pressure on the other lever, with out improvement, so that hasen't been a solution for me.

Same experience with my 2012 SR. Occurs from time to time and then goes away. I tried to lub the mech under the hood with some kind of WD40.

Your thumb button may be worn and in need of replacement. In its current condition, it does not always fully retract.

the shifters are practically new with less than 700 miles on it.

my 2012 SR11 also hangs in a similar fashion. like carbon 2329 said...' shift in the opposite direction...' and that clears it up. doesn't happen all the time, but on a 60 mile ride...it may happen 1-2 times at best.

i've checked all my cables and housing...changing it out twice. seems that its a mechanical issue within the shifters itself. tried everything...and finally gave up...since i know how to clear it from getting stuck.

I think it is something of a feature of the newer (red 11) shifters.
They shift cleaner and easier but locks up very easy.
The older 11 (white 11) is far less sensitive.

I have the problem all the time, when riding on the flats and my fingers easily doze off.
In the mountain it never happens (holding mostly on top of handlebar).
Campagnolos shifter have always locked up if you press both levers simultaneously, but nowhere near as
easily or as hard.

well, this is not good. it's a big problem if you are racing.

as i build up my second bike, i am having second thoughts on Record.

I have it occasionally but it doesn't bother me.

I have the same issue on my 2013 SR11. As the other posters have said, shifting the other way seems to clear it up. It's annoying if you ask me. Can the problem be isolated to the shifter (ie nothing to do with cables and rear derailleur)? If so, I might just send these back and replace them. If Campy bucks up with warranty, happy days, I'll have a spare set.
