I am thinking about replacing my Bontrager select crank, it's starting to make some funny noises from the bottom bracket. I know it's a cheap and fairly heavy crank but it has been pretty loyal, I would like to put on a new xt 770 and wondering if I would notice any performance increases that would justify the cost. Or should I doctor my bontrager up and find a better place to stick my money.
