I have a 2000 Trek 1000 bike. I really like the frame on this bike and it has always ridden very smoothly for me. I, however, can't seem to keep up with other bikers in the area that have better equipment, though my cadence seems to be the same as theirs. What would the next upgrade be? Chainring, bottom bracket, cassette?
I just started researching this and I already have tired head.
