CeramicSpeed 24mm Bottom Bracket

CeramicSpeed 24mm Bottom Bracket available in BSA or ITA

BSA Version

BSA is another way of stating English threading; it comes from British Standard Cycle. English threading on road bikes mean a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. It’s the most common threaded standard employed today. This kit works with 24mm diameter thru-axle cranks, found on Shimano, FSA, Rotor, among others.

or

ITA Version

Italian-threaded bottom bracket shells are typically found on Italian-brand road bikes. The shell measures 70mm wide and has a 35mm inner diameter.
This kit has all the pieces necessary to install 24mm diameter spindle cranks into an ITA shell. Those cranks come from Shimano, FSA, and others.

Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag.
