Description
ROTOR UBB 4630 bottom bracket – precision and durability for Pressfit 30
The ROTOR UBB 4630 bottom bracket is the latest addition to the Universal Bottom Bracket (UBB) family and was specially developed for the Pressfit 30 bearing standard . With an innovative threaded sleeve that connects both bearing shells, this bottom bracket sets new standards in terms of stability and smooth running.
The threaded connection effectively reduces the stresses normally exerted on press-fit sleeves and compensates for dimensional tolerances of the bottom bracket shell. This improves the parallelism of the bearings, resulting in smoother crank running and less noise. External bearing shells also increase the rigidity of the system, while the improved fit protects the bearings from overload and extends their service life.
An inner sleeve provides additional protection by protecting cables and electronics from friction with rotating parts. This makes the UBB 4630 bottom bracket not only a technically sophisticated but also a durable solution for your bike.
Highlights:
- Threaded sleeve: Improves stability and reduces stress in the pressfit system
- Precision and durability: Compensates dimensional tolerances of the bottom bracket shell for optimal bearing parallelism
- External bearing shells: Increase rigidity and ensure efficient power transmission
- Protection against overload: Better fit protects the bearings and extends their service life
