I've put it through the wringer

Shockingly spin-able. The amount of grease included pre-installed on the spindle interface is excessive but a super cool color.

It spins!

It's great that Shimano offers any size you need to fit your PressFit frame. They last a good while and are easily affordable!

Works Great

I've put it through the wringer

If you are looking for a reasonably priced bottom bracket to pair up with your Shimano crank this is it. Long lasting bearings and super easy to install.


Can this be used with Shimano XT Dyna-Sys FC-M785 Double Crankset?
