Enduro Bearings 2437 LLB (BB90) XD15 G3 Ceramic Bearing - 24x37x7mm

Want to make your bike faster than any other,Had enough of servicing your ceramic bearings so that they will survive another rainy day race andwould you rather have a bottom bracket outlast your frameset? Then you have arrived at the solution.

XD-15 ceramic bearings have it all - hands down the speediest, and longest lasting ceramic bearing available on the market. Nitrogen steel is the secret, precision machined and ground to ABEC-5 tolerances.These bearings spin with the very least resistance of anything Enduro have developed to date featuring oversized Grade 3 Silicon Nitride balls. On top of this, they will be spinning with the same ease one year or even two years from now, with longer intervals between servicing. No one else in the bicycle industry offers this combination of speed and durability: XD-15 bearings for wheels, bottom brackets, and drive train.

Made with Enduro LLB Type Seals, theirmost popular seal type, this is a Nitrile material rubber with a steel insert. Rather than the standard 2RS type seal, Endurogo a step further by machining a groove into the inner race where the seal can rotate with better efficiency and less rolling resistance. Rather than one thick seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the groove with light contact. The outside lip keeps the water and contaminates out, while the inner seal retains the grease for smooth function and long intervals between servicing.
