Ok so my XC bike NEEDS new cranks. I'm talking bent drive side crank needs. My 2 top choices are between LX and XT. I've heard great things about the XT's, haven't heard too much about the LX's (which isn't necessarily a bad thing). The only real reason I'm having the debate is I'm trying to keep the cost down, as I'm already replacing the rest of the drivetrain, and maybe the wheels. I'm no XC racer, I mostly ride XC for love of mountain biking, and as cross training for DH. Would I be fine with the LX's? Or should I pony up for the XT's? Any other options around that price point ($200 +/- ~$50)?
