Box Two 35mm Bottom Bracket Tripod Seats Length: 380mmThe Box Two 35mm Bottom Bracket is another incarnation of Boxs Oversized Technology design philosophy. Box admits this is a large bottom bracket, but they rationalize the design decision, by first moving material from less stressed areas to higher stressed ones, then they use Enduros precision bearings to create a near instant response to pedal input.
