Bottom Bracket Crankset Compatibility Chart for BB30 Pressfit BB386EVO and Shimano

Glory Cycles just posted this along with some photos of various bottom bracket sizes on frames from several manufacturers (shown after the break), and we thought it was worth sharing. It shows which common crankset spindle diameters and bottom brackets work with which standards either directly or with adapters.

Shown here from front to back are: 70mm Italian Threaded Pinarello, BB30 BMC and Look BB65 (which works with their ipack system that use a one-piece crankset with a ~50mm carbon fiber spindle and 65mm outside diameter bearing…it doesn’t refer to the BB width like most of the standards’ names).


  1. @ Fin – “True” BB30 cranks are designed for the outside width of the BB to be similar to that of a standard threaded shell thus giving you either increased heel clearance or lower q factor compared to outboard BB cranks, this means they have a shorter spindle than that of Zipp or Rotor so won’t work with their outboard BB’s.

What do you think?
