Box Two Oversized 30mm Alloy External Bottom Bracket jnrproperty -The bearingsThe 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.
