Descrição
BB30 bearings offer the best power transfer on the market and greater durability than the standard bearings on the market. Each bearing is mounted by hand in our workshop in France to offer the best precision of assembly and quality. Our bearings are used by the best professional teams in the peloton and by the best triathletes in the world.
The extreme hardness of the CyclingCeramic bead results in 4 to 5 times longer bearing life compared to standard bearings, our special grease helps keep your bearings watertight and protects them from external elements that can affect the proper functioning.
Silicon nitride balls are used to improve the performance of bearings. Ceramic balls are lighter, stiffer, smooth, hard, resistant to corrosion. They require less lubrication and have lower thermal expansion than their steel counterparts. Our beads are polished for 45 days continuously to obtain rounder and smoother balls. This makes it possible to reduce the contact surface to the maximum.
Details:
- Durability 3 to 5 times longer than conventional bearings.
- Ceramic beads 58% lighter, 121% stronger and 68% harder than steel balls.
- Grade 3 ceramic beads (polished for more than 45 days) for almost non-existent friction.
