2023 Ceramic Speed T45 Bottom Bracket for Shimano
T45 Bottom Bracket for Shimano
T45 is sometimes known as ThreadFit82.5, sometimes as the Colnago standard. This kit allows you to install Shimano and other 24mm diameter spindle cranks on your Colnago.
CeramicSpeed Bearings come installed in cups and are connected through the shell. There are 2 versions: Standard and Coated Bearings. Both have super round CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated Bearings 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.
In The Box
- 2 threaded cups with CeramicSpeed bearings installed.
- 2 dust covers.
- Spacer tube.
- All Round Grease.
- Sticker Sheet.
Technical Data
T45 was designed by Colnago to provide the design benefits of oversized bb shells and the repair benefits of threaded bottom brackets. These cups and bearings adapt the shell so it is compatible with Shimano, Rotor, and others.
The drag “cost” of our CeramicSpeed Standard Bearings is 0.3-.04 watts. That’s a reduction of 75% compared to stock bottom brackets. 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 last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our Standard.
All Round Grease comes applied to the bearings. 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 product is compatible with our T45 tool.
