Description

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.

This bottom bracket features nearly zero loss of power due to friction, thanks to the bearings. The bearings have super round, super smooth CeramicSpeed balls rolling on hardened-steel races. The Coated version has 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.

Features

Technical Data

30mm thru-axle cranks are increasingly popular due to their high stiffness and low weight. 46mm inner diameter bottom brackets are popular for the freedom they offer designers 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, it’s also nearly zero drag. Standard Bearings typically have a frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction versus conventional bb’s. The bearings last at least 3x longer than other bearings.

Change the grease for your rides. Race Day Grease, All Round, and Long Life are greased CS designed. The first is the least drag, the last is the most durable. All Round, in the middle, comes in road bearings.
