Trek Cema BB90/95 524556 Sram GXP bottom bracket

Perfect (Translated review)

Not tested yet but looks good. Let's see over time. (Translated review)

I thought I was buying the original TREK 524556 kit (BB TRK BB90/95 GXP KIT) as shown in the photo. In fact, I received a substitute CEMA kit that does not match the photo. The material-bicycle site is misleading as it mixes CEMA with the TREK 524556 code in the label. That said, this CEMA substitute kit fits but the chainring plates are offset by 1.5 mm outward (derailleur adjustment needed). This is the consequence of the 'GXP adapter ref. BB-A001A' delivered in the CEMA kit which protrudes by 5 mm compared to 3.5 mm for the inner ring of the original bearing (TRUVATIV / SRAM MR-22237-2RS). (Translated review)

Product as described but not tested. Fast delivery. (Translated review)

Sram bottom bracket for Trek fits well, installation not complicated if good tools, an installation manual would be nice!!! (Translated review)

It was the requested material, perfectly packaged and sealed in its original bag. The service was quite good considering the circumstances we are in. Nothing to complain about. (Translated review)

Fast delivery. Quite easy to assemble! Bearing side poorly protected, hence an average lifespan. Too bad... (Translated review)

Very fragile housing, first play in the bearing after 10 months (Translated review)

Quality bottom bracket. Mounted on a Trek, the bearings are smooth and durable. (Translated review)
