Ita 30 red

The ITA30 bottom bracket kit is an impressive design. Allows you to attach a 30mm spindle crank, such as Rotor's, to a 35mm diameter 70mm wide threaded bottom bracket shell. The bearings are installed in cups, which are then screwed into the bottom bracket shell. Those bearings are our standard or coated bearings. They both have super round, super smooth CeramicSpeed balls that roll on hardened steel races. The coated version has a metallic coating placed on the races, making them even harder and softer, resulting in a longer life and less resistance
