HAWK RACING
BB90 (Trek)
Regular price
€79,00
Introduced by Trek in 2008, BB90 bearings are pressed right into the frame, just like BB30, but without the need of circlips.
They can fit 24 mm cranksets like Shimano (Dura Ace, Ultegra 105...), Rotor Aldhu24 or Vegast24, or SRAM GXP (with the use of an adapter).
Since 2019, Trek has dropped BB90 in favor of T47 standard.

NOTE : To avoid any unpleasant creaking, you may consider using some retaining compound like Loctite 609 instead of grease.
