BB30 - New BB Industrial Standard

The BB30 system is new BB industrial standard. The BB30 crankset is 10% stiffer, 20% lighter, and provides 300% more ankle clearance than the GXP system. The results are an impressive increase in rigidity in the frame and crankset, better durability, lighter weight, and more ergonomic design for the crankset. With so many advantages, it’s hard to deny the validity of this system.
