|Campy record right shifter problem||PaulCL|
Nov 3, 2001 7:36 AM
|Rode 65 miles last weekend without a problem. Got up Thursday early AM for a ride, but had to come home early. why?? My right shifter just wouldn't shift. I could get it to upshift/downshift a couple of cogs but that's it.
Nobody played with the cable. I didn't hit the shifters. Any ideas??
I've been playing with it for better part of an hour with no luck. The cables are only about 800 miles old, the shifters about 5500 miles old. It doesn't seem to be a matter of adjustment. Could there be something within the shifters that I should look at?? I'm at a loss. Thanks. Paul

|If the cables are only 800 miles old, this shouldn't be a problem, but push the cable out of the lever and make sure that the end of it isn't frayed or even broken. Ergo shifters require the shift cable to stay coiled in a very tight radius curve, which can cause pre-mature wear. This is the possible cause, but again, with only 800 miles, probably not likely.
As a head's up to others, it is better for your bike to store it in the small chainring/small cog combination- this puts the least amount of stress on both your cables and derailluers.

|Thanks for the input. Maybe you can help a little more...
...no jams or gunk under the bottom bracket.
...I lubed under the hoods
...the cable is not frayed
...when the cable is disconnected, or slack, the shifters work fine. When I pull on the cable, the rear derailleur moves to the larger cogs.
Here's the symptom...(in the stand)...when in the smallest cog, trying to shift to a larger cog, the cable is so taught that the shifter can't click up (or pull the cable anymore). If I slacken the cable by hand, then the shifter shifts properly (without any cable force against it). I've diconnected the cable making sure it wasn't gummed up. Without cable tension, the shifters appear to work fine. I'm stuck.
I'm not a mechanic, but I can usually handle most problems, but this has me baffled. One day all is fine, the next, it won't shift at all.
...a thought or a shot in the dark...within the shifter mechanism is there some sort of "release" on the thumb shifter which is not working under tension but will work without cable tension?? Make sense or am I grasping at straws?

|I've had this problem before, now if I can only remember the solution...
Look carefully inside the slit where the cable is inserted, you should be able to see the ratchet mechanism. From time to time, a piece of handlebar tape will get itself lodged into the mechanism and jam things up like you describe. You may have to (ugh) rebuild the lever...
I don't think this is your solution, but it's common Ergo problem #2.
|Hey TJeanLoz...the problem is solved||PaulCL|

|I was all set to rebuild the shifters, when I decided to bring it to my LBS first. Guess what? He put it in the stand and it shifted perfectly. Go figure?? Our best guess is that the shifter got wet, dried out, was in deperate need of lube and took a day or so for my lubing to work its' way into the shifter. Doesn't hold up as a good reason for me, but the things work now. I don't understand it at all.
Its' kind of like bringing your car to the shop with a bad problem, only to have the problem dissappear the minute the mechanic opens up the hood. Thanks. Paul
