TECHNICAL SPECIFICATIONS

With the benefits of both oversized shells and the tight fit of threading, T47 has the best of both worlds. These cups and bearings make it possible to run stiff and light 30mm spindle cranks, like those from Rotor and FSA’s 386EVO standard.

Standard Bearings reduce drag by 75% versus stock bottom brackets, dropping down to 0.3-0.4 watts per set. This is the result of hardened-steel races rolling ceramic balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer. 

Coated Bearings feature an even longer lifespan and even lower drag. Life increases by 60% and drag drops by 50% compared to our Standard. 

Applied to the bearings at the factory is All Round Grease. It can be replaced for lower drag Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.

This BB is compatible with 68mm frames.
