Wheels Manufacturing's BB30 to outboard bottom bracket is designed for installing 24mm cranks, Shimano, FSA and the like, into BB30 frames without the need for any adapters. The cups are machined aluminium, anodised in black or red, and made in the USA.
Inside are Enduro ABEC 3 sealed bearings with a dual silicone seal that keeps contamination out for longer life. It suits bottom bracket shells 68mm to 73mm wide with a 42mm inside diameter, and the unit weighs 153g.
