Kogel Bottom Bracket BB90 to 24mm Road Seals
Kogel Bottom Bracket BB90 to 24mm Road Seals Info
The Kogel Bottom Bracket BB90 to 24mm Road Seals is built for Trek carbon frames with a BB90 shell, giving you a direct replacement that pairs ceramic bearings with road-optimized seals. The result is a bottom bracket designed to run smoothly over the long haul — minimizing friction without sacrificing durability. Compatible with 24mm spindle cranksets from Shimano, Rotor, and SRAM GXP, it covers a wide range of common road drivetrain setups.
Kogel hand-assembles their bottom brackets, and the road seal spec here reflects a deliberate tradeoff: lighter contact seals that prioritize rolling efficiency over the heavier protection you'd want in wet or muddy conditions. If your riding is primarily on pavement, that's the right call — less seal drag means more of your effort reaches the rear wheel.
