Kogel BB30-DUB ceramic bottom bracket, 30 mm, SRAM DUB / ROAD
This bottom bracket is compatible with Sram DUB cranks with a 30 mm axle diameter and frames with BB30 specification.
Main advantages of Kogel ceramic bearings
- guaranteed performance warranty
- Kogel ceramic bearings are more symmetrical (i.e. round) and manufactured with tighter tolerances than steel bearings
- they are more efficient in power transfer than standard bearings
- Kogel also supplies service kits and seals so that the bearings can be serviced and last as long as possible
- Silicon nitride (the material used to make the bearing balls) does not corrode and is extremely resistant to wear
- BB Boost® technology
- placement of bearings as close as possible to the crank arms to increase stiffness and durability
- two-year minimum warranty for smooth operation (after the first year, professional service must be performed, then the warranty is extended for another year)
