Problem with Campy shifter
Hi folks.
I bought new Chorus brifters and derailleurs about 5 months ago for my Kish gravel bike. Im having a problem with the right shifter. It shifts up (to larger cog) fine. But when shifting back down it gets jammed about half the time. To unjam it I have to shift back up one or more times before it will shift down. The cable does not look kinged. Bottom bracket lead is clean. I trimmed the hood a bit to allow the thumb paddle to return smoothly. I have had problems with the return spring on Campy shifters in the past. I hope that this is not a problem on this new shifter. What do you think? Thanks. Dan

If the upshift button won't move, pull the downshift lever out as far as it will go, to see if the upshift button frees up (likewise, if the downshift lever won't move, pull the upshift button up as far as it will go to see if the downshift lever frees up. On the other hand, if the upshift button does move and gives the usual "click" but the derailleur doesn't move, then problem is more likely downstream, either in the cable (sticky or kinked cable) or the derailleur (sticky parallelogram pivots). |

Hesitancy or outright refused shifts. Goes away with slightly warmer weather. Don't know if it's carbon vs alloy, different grease or the benefits of ball bearings. Or something else.

What's the purpose of that tiny grommet/washer?

11s feature and just a standard and flat place for the der housing to push against.

But, even in cold weather, it really only does it when I get sloppy.

Thanks Guys.
After ready your replies about the importance of frictionless cable run, I took a real close look at the cable and housing. I found a small kink in the cable as it was exiting the down tube thumb screw. I replaced the cable. No problem on the ride yesterday. Good to know Mr. Old can service Campy. Not much Campy expertise out there these days. Dan
