PF4630 Bottom Bracket Gravel
This bottom bracket is when you have a PF30, BBright, or 386EVO shell frame and want to install a BB30 crankset into the frame. All have a 46mm inner diameter and smooth insides, though the widths vary from 68mm to 86mm. The crank has a 30mm diameter spindle.
Our Gravel bottom brackets are built with CeramicSpeed Coated bearings and equipped with UFO Long Life Grease for the ultimate in durability and protection in all environments.
This bottom bracket features nearly zero loss of power due to friction, thanks to the bearings. The bottom bracket has super round, super smooth CeramicSpeed balls rolling on hardened-steel races. With a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag. They come installed in cups.

Technical Data
30mm thru-axle cranks are increasingly popular due to high stiffness and low weight. 46mm inner diameter bottom brackets are popular for the freedom they offer designer in building frames. Because of the variety of widths, the cups here extend into the shell and come with a telescoping spacer tube to further seal and stiffen the system.
The bottom bracket is already stiff thanks to hard ceramic bearings and hardened-steel races. Thanks to CeramicSpeed, itÕs also nearly zero drag.
