Box One B52 Bottom Bracket
Box One B52 Bottom Bracket
Traditional bottom brackets can limit stiffness and efficiency. The B52 changes that, using Oversized Technology™ to deliver a stronger, more responsive ride.
With a 52mm x 80mm shell, it allows for wider chainstays, improving power transfer, cornering stability, and acceleration. The result? Less energy wasted and more efficient performance on every ride.
Key Benefits
- 52mm oversized shell increases stiffness and durability
- 80mm width supports wider chainstays, reducing flex
- Captured bearings handle higher torque and run smoother
- Improved power transfer and responsiveness
- Reduced vibration and longer service life
- Optimised for Box M35 spindles and cranks
A solid upgrade if you’re looking to get more out of every pedal stroke.
