The Box Two Oversized Alloy External Bottom Bracket follows on Box's Oversized Technology engineering philosophy. Material is moved from low stress to high stress areas creating a bottom bracket with less deflection and more quickly applied pedal power. For this bottom bracket Box has toned down the Oversized Technology a little bit in relation to their top of the line M35 model. The 30mm cross section is designed to work with the other M30 components in Box's lineup.
