I have a question, I'm looking to get a new lighter crankset and was wondering what is a good weight? I've seen whole set's weighing sub-800g and then 900+g. I don't need the absolute lightest but I'm currently running: Crankset - Custom Shimano Hollowtech, Octalink XT Spline (this came stock on my FSR XC Pro). I know it's not the lightest so any suggestions on possible lighter replacements, that aren't XTR expensive? Thanks a lot.
