What that means for you if moving your cranks over to the new bike is...they will be plug and play...no adapters needed...or...if they are external threaded bearing cranks on your '11 bike with adapters...just bring all hardware over to your new SL3. The reason for this is...BB-30 and PF-30 is interchangable for cranksets...cranks can't tell the difference between the two...same spacing and same bearing ID.
