2023 Ceramic Speed T47/86 Bottom Bracket for SRAM GXP

T47/86 Bottom Bracket for SRAM GXP

T47 is a newer bottom bracket shell design, utilizing the oversized interface of PF30 and EVO386, but with the benefit and peace of mind of a threaded interface. This BB allows you to install Quarq and SRAM 24/22mm spindled cranks into a T47 frame.

Also compatible with TREK T47 85.5mm wide frames.

There are 2 versions: Standard and Coated Bearings. CeramicSpeed bearings come installed in cups and are connected through the shell. Both have super round CeramicSpeed balls and hardened-steel races. The Coated have an additional attribute: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, lowering drag and increasing life.

Bottom Bracket tool for installation: BBT-47.

Technical Data

With the benefits of both oversized shells and the tight fit of threading, T47 has the best of both worlds. These cups and bearings adapt the shell so it is compatible with 24/22mm diameter spindle cranks.

Also compatible with TREK T47 85.5mm wide frames.

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 combined with 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.
