Kogel Bottom Bracket BB90 to 24mm Gravel/MTB Seals
Kogel Bottom Bracket BB90 to 24mm Gravel/MTB Seals Info
The Kogel Bottom Bracket BB90 to 24mm Gravel/MTB Seals is built for Trek carbon frames with a BB90 shell, giving you a direct replacement that accepts 24mm spindle cranksets — including options from Shimano, Rotor, and SRAM GXP. Kogel hand-assembles each bottom bracket around ceramic bearings, which run smoother and hold up longer than standard steel under consistent load.
What sets this version apart is the reinforced gravel and MTB seal package — designed to resist moisture and debris ingress in the conditions where press-fit bottom brackets most commonly fail. If you're running a BB90 Trek through wet gravel rides, muddy singletrack, or mixed-surface training, this seal spec is the appropriate choice over Kogel's road-oriented offerings.
