BB90 Bottom Bracket for Trek Shimano

BB90 for Trek Shimano

BB90 is the Trek oversized bottom bracket standard and is only found on Trek road bikes. The shell is 90.5mm wide and is designed to work with 24mm spindles and road cranks and have the bearings inside the shell. The CeramicSpeed Bearings come as two bearings, which are then pressed into the frame.

Those two bearings consist of either CeramicSpeed Standard or Coated Bearings. Both feature super smooth, super round CeramicSpeed Balls contained in hardened-steel races. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in lower drag and longer life.

In The Box

• 2 dust covers with integrated spacers.
• 10ml syringe of All Round Grease.

What is Coated?

Our coated products have a 6 years warranty. The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version
