BB30 Shimano 24mm bottom bracket

Bottom bracket - BB30 for Shimano

The BB30 24mm bottom bracket combines low-friction ceramic bearings, providing greater durability than standard bearings. Their high quality finish allows them to achieve high performance. Designed to offer lightness and maximum protection thanks to their seal design.

The extreme hardness of CyclingCeramic balls guarantees a longevity 4 to 5 times greater than that of standard bearings. The special grease keeps the bearings sealed and protects them from external elements harmful to their proper functioning.

Silicon nitride balls improve bearing performance. Lighter, more rigid, smooth, hard and corrosion resistant than steel balls, they require less lubrication and have lower thermal expansion. Polished for 45 days to obtain a rounder and smoother surface, thus reducing the contact surface as much as possible.
