Ergo shifters are sticking, how do I fix this?dealy663

Hi,

I have a set of Campy Daytona ergo shifters, that have had a problem with sticking on the thumb operated levers. These shifters have about 1200 miles on them, and have had this occaisional problem ever since new. The guy I bought the bike from said that ergo shifters should break-in and loosen up after a while, but this hasn't happened yet.

This used to happen maybe once or twice a week, but lately it is more like 3 or 4 times aday. It happens on both shifters. So when I go to push the lever it will refuse to budge. So I then release pressure on the lever and try again, this usually works. But sometimes I have to try again two or three times.

Is there a lube point in these shifters?

Any other suggestions on how to make things work a little more smoothly. It is pretty frustrating not being able to snap off a shift, especially when approaching the next climb.

Thanks, D

I had that happen with mine, and found the cable had frayed inside the shifter. However, I had about 9 or 10 thousand miles on it. Just something to check if all else fails.

My wife's bike had this problem...gemcity

The thumb-button was sticking down, which left the ratchet engaged. Have a close look (from below). You will probably see the same thing. I lubed the hell out the thing with Tri-Flow on the pivot-point of the thumb button. Things loosened-up and the problem has gone away (for now?).

See my appeal for help on this problem: "Campy Mirage Shifter Problem." My wife had this problem since the bike was new. I think the pivot was too tight from manufacturing. Others suggested it is caused by dirt or sweat.

Hope that helps.
Flush & lube, among other thingsKerry

First thing is to flush and lube. Peel back the brake lever hood and you might see a small hole in the lever body. Not intended to be a lube port, but it works pretty well. Squirt solvent or a lube like ProLink or TriFlow down there while working the levers. Your problem could just be gunk. Also, look at whether the hood is binding anywhere around the thumb lever or the mechanism. The hoods have a number of "nubs" which are supposed to fit into indents in the lever body. If things aren't in place, you can get interference. As mentioned in another post, frayed or kinked cable could be a cause. With nearly 5 seasons on my Ergo levers, I have experienced your problem, but never repeatedly (maybe 10 times a season, quickly resolved by an "up/down" shift.
