CeramicSpeed BB90 Bottom Bracket for Trek Shimano

The CeramicSpeed BB90 Bottom Bracket for Trek Shimano is made for the Trek BB90 oversized bottom bracket standard found on Trek road bikes. The shell is 90.5 mm 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 pressed into the frame.


The CeramicSpeed Difference

CeramicSpeed Standard Bearings last at least three times longer than other bearings. That’s thanks to hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than other ceramic bottom brackets. CeramicSpeed bearings have a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to other BBs.


Coated Finish Option

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 the standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible with the coated version. CeramicSpeed coated products are covered by a lifetime warranty.


The CeramicSpeed BB90 Bottom Bracket for Trek Shimano is designed to work with 24 mm thru-axle spindles. The bearings work with Shimano and other 24mm thru-axle cranks, such as FSA.
