Box Two 35mm Bottom Bracket

Box Two 35mm Bottom Bracket

Built around Box Oversized Technology, the M35 bottom bracket is designed to maximise pedalling stiffness and power transfer. Developed alongside Box cranksets, it ensures more of your effort goes straight to the rear wheel.

By increasing the spindle and interface size, flex is reduced and bearing contact is increased, giving you smoother power delivery and faster, more responsive acceleration.

Key Benefits

• Extreme 35mm oversized spindle for maximum stiffness

• Reduced flex for more efficient power transfer

• Large precision bearings for smooth, durable performance

• Reinforced high-stress areas for added strength

Key Info

• Uses Praxis™ M35 interface

• Fitted with Enduro precision bearings

• Requires a compatible modern frame

A high-performance option for riders who want the stiffest, most responsive setup possible.
