The GXP system does not rely on a lateral load to adjust the bearing clearance as other systems do, but the left bearing is clamped between the bottom bracket axle and the left crank arm. This allows the right-hand bearing to move axially freely on the bottom bracket axle. This prevents premature bearing wear.

This steel bottom bracket allows for use of FSA mountain bike cranks with MegaExo 24 mm axles in BB30 bottom bracket housings.

You've decided that your bike's performance features could be enhanced with components selected á la carte — and that you should be able to accomplish this despite the spawn of deviant bottom bracket "standards" that have created component compatibility issues at your local bike shop. Conventional threaded bottom brackets like your Italian-threaded BB shell shouldn't foil plans to upgrade your ride. ROTOR conceived its Universal Bottom Bracket (UBB) concept to eliminate the complicated bottom bracket/crank compatibility challenge that has increasingly frustrated the mechanics at your LBS. The BB1 ITA is the "yes" component to "Is this compatible with my Italian-threaded BB shell with a 24mm axle?"
