The Shimano CeramicSpeed BB90 Trek bottom bracket is the standard large Trek bottom bracket and is only found on Trek road bikes. The housing is 90.5 mm wide and is designed to work with 24 mm road axles and rods and has the bearings inside the housing. The CeramicSpeed bearings come as two bearings, which are then pressed into the frame. These two bearings consist of CeramicSpeed Standard or Coated Bearings. Both feature super-soft, super-round CeramicSpeed balls contained in hardened steel races. The coated version has a metal coating placed on the races, making it even softer and harder, resulting in less resistance and longer life. BB90 is simple and lightweight. The standard is designed to work with 24 mm thru-axis shafts. The bearings work with Shimano and other 24 mm thru-axle connecting rods, such as FSA. Standard CeramicSpeed bearings last at least 3 times longer than other bearings. That's thanks to hardened steel races and ceramic speed balls that are 100% softer and 15% harder than ceramic competition. These bearings have a friction drag of 0.3-0.4 watts per set, representing an average reduction in drag of 75% compared to bb stocks. Bearings coated with CeramicSpeed reduce resistance by 50% compared to standard bearings and improve service life by 60%. To better match performance to your needs, consider the fat you are using. All Round Grease comes installed, but can be replaced with lower drag TT and tracking grease, or longer lasting LongLife grease, which adds a little drag but stays inside when driving in cluttered conditions.
