• 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

• 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.
