BB30A (73mm) DirectFit Shimano


Size Guide
Frame Set
  • If you're looking for a 73MM bottom bracket that will never creak, and spins like mad, you've come to the right place.

    The BBInfinite BB30A (73mm) DirectFit Shimano module works with all Shimano HollowTech road cranksets on the market, from Tiagra to Dura Ace. Our BB30a bottom bracket ships with the special press tools and retaining compounds you'll need.  All you need is the press.

    This product will not fit a CAAD12 Disc brake bike or a Synapse Alloy Disc brake bike due to internal routing of the brake hydraulic line through the frame bottom bracket shells of these models.

    This does not fit ANY SuperSix Evo models as they are PressFit30A, not BB30A.
