T45 is a threaded bottom bracket standard with an 82.5 mm wide shell, used mainly on Colnago frames. Like T47, it gives you quiet, easy-to-service threaded cups with room for larger spindles.

Our T45 bottom brackets use Tripeak's 3-in-1 core system, so one bottom bracket fits Shimano Hollowtech II (24 mm), SRAM DUB and 30 mm cranks.
