SPECIFICATION
SPECIFICATION
T47 is an open standard designed to provide the benefits of both oversized shells and the tight fit of threading. These cups and bearings adapt the shell so it is compatible with 24mm diameter spindle cranks.
Compatible with 86mm wide frames, and also compatible with TREK T47 85.5mm wide frames.
Our CeramicSpeed Standard Bearings reduce drag by 75% when compared to stock bottom brackets. Down to 0.3-0.4 watts per set. This is the result of hardened-steel races combined with CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer.
The CeramicSpeed coated Bearings feature an even longer lifespan and even lower drag. Life increases by 60% and drag drops by 50% compared to our CeramicSpeed Standard Bearings.
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.
