KOGEL BB30A for 24mm / GXP - Cross Seal
Kogel offers the gold standard with their tailored seal, high quality ceramic bottom brackets. Your bottom bracket is critical in transferring power from your legs to your wheels, so you should want the best available. Kogel's line of ceramic bottom brackets work to minimise friction, maximise stiffness and last for years. The silicon nitride ceramic bearings used by Kogel are harder, smoother and rounder than even the highest-grade steel balls, and are even immune to rust.
Cross seals are built to have the best protection against the elements, and are recommended for off-roading, though they are best for any cyclist seeking longevity from their bearings.
Features
- More symmetrical (i.e. round) and built to stricter tolerances than steel bearings
- More efficient for power transfer than standard bearings
- Won't deform, flat-spot, crack or get pitted
- Top-tier grade 3 ceramic balls are the best selection for bicycle applications (Ball grade rates the roundness of the ball)
- Standard “cross” seals for optimal balance of durability and ceramic efficiency
