Box Two Oversized Alloy External Bottom Bracket

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.
