Why won't my bike shift well?
New chain? Check
New cassette? Check.
Adjusted with love and care? Check.
What of what could cause the normally-delightful Ultegra 6700 to shift like ... like something that doesn't shift well?
I'm getting ready for some long rides and thought I should do the new cable thing. I got Gore Ride-on brake and shift cables. Son of a gun, when the right shifter cable came out is was frayed as all get out.
New cables = wonderful shifting. And oh, what a pain if it had broken in the middle of nowhere.
I'd had a similar issue with my 6600 Ultegra brake/shifters. The end actually came off and took forever to dig out. I wonder if this is a design problem, that perhaps they route the cable through too may turns. I don't think this should have happened after only 4500 miles.
