T47 for Ø24mm

T47 is a threaded bottom bracket standard originally designed by Chris King company. Its purpose was to accomodate all the cranksets currently available on the market (from Ø24 to Ø30mm), without sacrificing quality of bearings or threading thickness.

This standard has been recently adopted by brands like Trek or Look.

Hawk Racing T47 should be used to fit Ø24mm cranksets like Shimano (Dura Ace, Ultegra, 105...), Rotor Aldhu24 or SRAM GXP (with the use of Hawk Racing GXP adapter) on frames with a 86.5mm shell width.

Note: Trek T47 frames have a shell width of 85.5mm. You will need 0.5mm spacers on each side to fit Hawk Racing T47 for Ø24mm.
