Kogel Bottom Bracket T47-I to 24mm Road Seals
Kogel Bottom Bracket T47-I to 24mm Road Seals Info
A bottom bracket lives in a part of the bike that accumulates road grit, water, and chain lube — so bearing quality and seal design matter more than most riders realise until something starts creaking. The Kogel Bottom Bracket T47-I to 24mm Road Seals is a hand-assembled, ceramic-bearing T47 internal unit built to address both concerns: it threads cleanly into T47 shells measuring 85.5mm or 86.5mm and accepts 24mm spindle cranksets across Shimano, SRAM GXP, and Rotor platforms.
The road seal spec is a deliberate choice — lower rolling resistance over maximum contamination protection, which is the right trade-off for pavement riding where drivetrain friction compounds over every kilometre. Kogel assembles each unit by hand, with ceramic bearings selected and installed to tighter tolerances than mass-produced alternatives. Installation requires a T47-compatible splined tool.
