SRAM Force Front Shifter Problem
My road bike is outfitted with SRAM Force components. About a month ago, I started to have inconsistent shifts with the front derailleur. Most of the times when I shifted to the big ring, the front derailleur would click back a bit and rub on the chain regardless of the gear I was in on the rear cassette. Occassionally, when I upshifted, the front derailleur would stay where it's supposed to be and not rub the chain.
However today it didn't work at all. When I tried to shift to the big ring, the derailleur would move, but as soon as I stopped pushing the shifter, the derailleur would drop the chain back onto the small ring. I must have tried it 20 times, but it never worked. And it sounds like there's something loose inside of the shifter as I hear some rattling as well.
Has anyone heard of this problem before? Is this something that's user servicable or do you think I have to send it in to SRAM?
Did you check your cable tension? also you may have a cable that is starting to fray at the cable head. Pull out the cable to check.
Sram shifters are serviceable in theory but sram doesnt sell the parts to service the shifters. They do have a very nice crash replacement policy ($50 a shifter)
