I have a Giant Cypress DX, which has a 7-speed cassette and a triple crankset. I've been having a lot of shifting issues lately, and yesterday the right grip-shift broke, so the only way to keep the bike in a particular gear is by holding the shifter in place.
I know I could just replace the shifter for $20-30, but I had already been thinking about converting to a double and was wondering how to tell if a particular groupset is compatible with my bike. Most of the double crank groupsets I was looking at were for road bikes, so the shifters wouldn't work on a flat bar.
Anyone have any ideas?
