Hey man,
Hope you're doing well. Do you know if the SRAM 100 crankset will fit a square taper BB, or do I need to pop in a new SRAM BB? I see on your site that the SRAM 300 Crankset has the BB included so I'm assuming it's a proprietary fit. Also, is the 300 a significantly better crankset than the 100 for the few extra bucks? And, finally, given that the SRAM BB's seems to be fairly inexpensive, regardless of fit, is it worth it just to pop in a new BB when upgrading the crankset? My bike has a standard English thread if that matters at all.

Thanks in advance man! I appreciate your insight.

Best,
Matthew
