Campy shifter problem(11 posts)

It's more of an intermittent problem than anything else, actually:

From time-to-time, when I try to shift into a smaller cog [usually from 19t to 17t or 17t to 16t], the thumbshifter seems stuck and nothing happens [no shift]. If I try again a couple of times, it shifts. Now, this has only happened a few times, and never when shifting under load.

Any idea what the problem might be, and what I can do to ensure that it doesn't happen again?

I can think of two obvious candidates. Make sure the thumb lever and its slot isn't obstructed by the hoods or by bar tape. Second, if you depress the finger lever, that will lock out the thumb lever.

I can vouch for the Ergo shifter lockout. If you put even slight pressure on the finger lever, the thumb lever will lock out, and vice versa. I had the same problem when I first got my Campy stuff and discovered the lock-out problem by chance. I realized I was leveraging against the thumb lever...

So, it's probably just a question of inadvertently putting pressure on the finger [blade] shifter when I try to shift with the thumb shifter? Makes sense... that's why it's intermittent. I should just be more careful, thanks...

I don't know what group you have, I remember my Athena group when new was very stiff and sort of hard to use the thumb from the drops. Over time they broke in and then just shifted smoothly every time. If this is new this may also be the problem. Do you have this problem when shifting from the hoods? I never did as the added leverage allowed me to more evenly aply the pressure needed.
I might ad I just put a new Record 10sp on my new bike. I was very suprised after my prior experience how easilly they shift right out of the box.

larger cog). I shot some lube in there, and whatever it was worked it's way out.
I realize that you have a different problem, but a little lube never hurt anyone.
What do you suggest?Velocipedio

3-in-1? Pedro's? White Lightning? WD-40 (gasp!)?

You should probably use some Prolink or a non wax-based dry lube in there. I take it you're still having problems?

but one of the sages of this board said give it a shot, so to speak, and it worked.

No... the problem is intermittent. I haven't had it for a few days now. It's just that I'd rather do something preventative now than be out on a century, stuck in 13t...

How old are your levers? If they're fairly new, then the suggestions you've been given ought to solve your troubles. If they've got 10k+ miles on them, then maybe you need to be concerned about tired springs and/or cams. I'd play with the shifting with the bike on a workstand to make sure the problem is, indeed, intermittent. If it's not, then solve the obvious problems like those you've already been given while you determine the exact circumstances under which you can duplicate the fault.
