I was recently given an older Trek 7100 that is overall in good condition. The one issue is that the rubberized grips on the grip shifters have degraded to a black goo that gets on your hands like tar. Basically the bike in unridable unless you put on disposable gloves, otherwise you will have black goo on your hands for the next day or so no matter how hard you wash them.
I am going to wrap them in grip tape like people wrap around golf club or tennis racket handles and weight bars in the short term to see how I like the bike and if there are any other issues.
In the longer term I would like to replace the shifters to fix this right and would like to go to trigger shifters if at all possible. It looks like the rear 7 speeds are controlled by a SRAM 3.0 shifter and derailleur. The front 3 speeds are run by a Shimano C102 derailleur and twist shifter. I understand that this is not a high end bike and was not from day one but is a decent basic commuter or such.
I am not an expert on this type of thing but it looks like there are many factors to consider and that you cannot just use any 3 speed and 7 speed trigger shifter to perform this upgrade. I saw reference to the fact that I would need to purchase new old stock Shimano components from a source like eBay to perform this but no new parts are currently made that are compatible. I did watch a video where a guy used new Shimano Tourney shifters but then had to replace the cassettes. I don't know if that was needed or if they were incompatible parts. Since this was a free bike and not a real valuable one, plus most of the components are in good condition, I want to do this right but not replace otherwise good serviceable parts.
Anyone with more experience have any suggestions?
Thanks,
