I have a 92 Rockhopper and I'd like to get some higher gear ratios out of it because I'm doing a lot of road biking with it. It's equipped with Shimano 400LX front and rear ders. and some crappy bio-pace chainrings. The fronts are 48/38/28 and the rear is 13x30. I did some reading and I'm not really quite sure what it means to have rivetted chainrings ... maybe someone can fill me in. They look easy to remove, but I've never tried. My front der. cable runs alongh the down tube and around the bottom bracket.
Is a bio-pace 48 any different than a regular 48 ring? Would my best bet be to replace the cogset to an 11xsomething? Any advice would be great.
