The CeramicSpeed BB86 bottom bracket convinces by its design and harmonizes with cranks with a 24 mm axle, as from Shimano and FSA. The bearings are mounted in the bearing shells, which are then screwed into the bottom bracket housing. These bearings are either standard or coated bearings. Both have super round, super smooth CeramicSpeed balls made of hardened steel. The coated version has a metallic coating on the raceways that makes them even harder and smoother, resulting in longer life and lower resistance.
CeramicSpeed standard bearings typically have a frictional resistance of 0.3-0.4 watts per set. This is in the range of 75% resistance reduction compared to standard bottom bracket bearings. This is due to ball bearings that are 100% smoother and 15% harder than their ceramic competitors. The bearings last at least three times as long as other bearings.
Highest quality / Reduced friction / Easier and smoother running
3- 5 times longer service life compared to standard bearings
Power saving with the help of a complete Ceramicspeed upgrade 10-16 Watt
