ITA30 Bottom Bracket Gravel
The ITA30 bottom bracket kit is an impressive bit of design. It allows you to mate a 30mm spindle crank, like those from Rotor, to a narrow 35mm diameter, 70mm wide threaded bottom bracket shell.
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.
The bearings come installed in cups, which are then threaded into the bottom bracket shell. Those bearings are Coated Bearings. They have 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.

Technical Data
Italian threading can be found on many high-performing Italian-built bikes. The threaded extension is thin, as they need to fit a 30mm spindle inside the 35mm shell.
The oversized spindle was designed to be stiffer and faster, same as the CeramicSpeed system. CeramicSpeed Coated bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. That’s thanks to balls that are 100% smoother and 15% harder than the ceramic competition. The bearings last at least three times longer than other bearings.
