Kogel BB90 24 ceramic center compound for GXP / ROAD
Even new bikes equipped with top-of-the-line components usually come fitted with a sub-par center assembly of bearings and plastic cups.
Even with perfect maintenance, these steel bearings simply will not roll as efficiently as our high quality ceramic bearings.
The main advantages of Kogel ceramic bearings:
Guaranteed performance guarantee.
Kogel ceramic bearings are more symmetrical (ie round) and manufactured to tighter tolerances than steel bearings.
They are more efficient at transmitting power than standard bearings.
Kogel also supplies service kits and seals so that the bearings can be serviced and last as long as possible.
Silicon nitride (the material used to make the bearing balls) does not corrode and resists wear for an extremely long time.
BB Boost® technology. Placing the bearings as close as possible to the crank arms to increase stiffness and durability.
Proof that KOGEL Bearings believes in its products is a two-year minimum guarantee for smooth operation (after the first year, a professional service must be performed, then the guarantee is extended for another year).
