I have an old Trek 800 mountain bike that has a three chainring crank, and a 6 speed freewheel. The index shifters for the rear derailleur seem like they are about to fail. I think some part has worn down in it, and often when I press the lever to shift to a larger cog, there is no tension on the lever.
I'm going to inspect the shifter some time soon, but in the event that I can't fix it, can anyone recommend a good set of replacement shifters for my bike? Most of the stuff that I've seen online is for 8 and 9 speed bikes. I haven't found any 6 speed index shifters except for some grip shifters.
Where can I find some good 6 speed mountain bike/hybrid shifters? Does anyone make friction shifters for mountain bike/hybrid style upright bars?
Thanks in advance.
