The Trek Integrated BB90 Shimano V2 Oversized Bottom Bracket Bearing is a genuine Trek replacement bearing designed for BB90 and BB95 systems with slightly oversized bearing bores.

This V2 Oversized version features a larger 37.1 mm outer diameter to improve bearing fit in frames where the bottom bracket shell has developed slightly increased tolerances over time.

Why choose the V2 Oversized version

On BB90 and BB95 systems, bearing seats can gradually develop larger tolerances over time, potentially causing creaking noises or bearing movement.

The V2 Oversized version was specifically developed to improve bearing retention inside the frame thanks to its slightly larger outer diameter compared to the standard version. 

It is a widely used solution for maintaining Trek BB90 and BB95 frames with mild bottom bracket shell wear.
