I've started having problems with the front shifter (RSX) in my trainer bike recently, and I was
wondering if anybody here had some advice.
The problem is that the front shifter will often not shift down to a smaller chainring. I move the
small lever all the way, but I feel no resistance, nothing engaging. If I repeat it enough times
(10-20 or even more), eventually it catches on and downshifts.
Needless to say, that's not what I want after I do an intense 3-minute interval and I have a 20
second break :-)
Any suggestions of what might be wrong? Is that something I can fix, or is the shifter shot and I
should buy some cheap downtube shifter replacement?
Any suggestions appreciated. Thanks!
