CyclingCeramic T47EX Sram GXP 68mm Screw-in Case Black

CyclingCeramic bottom brackets are combined with ceramic bearings with low friction and more durable than standard bearings. The high quality finish of the bottom brackets allow them to achieve high performance. They have been designed to offer a light set and, thanks to the design of the seals, allow maximum protection. The extreme hardness of the CyclingCeramic balls gives rise to a longevity of the bearings 4 to 5 times greater than standard bearings, the special grease keeps your bearings sealed and will protect them from external elements that could affect proper operation. Silicon nitride balls are used to improve the performance of bearings. Ceramic balls are lighter, stiffer, smoother, harder, corrosion resistant. They require less lubrication and have lower thermal expansion than their steel counterparts. The balls are polished for 45 days continuously in order to obtain rounder and smoother balls. This thus makes it possible to reduce the contact surface as much as possible. Details: Compatible Sram GXP 24-22mm crank axle / frame internal diameter 47 mm / width 68mm (to screw) Aluminum 7075.
