This is a thread fit BB that is compatible when combining a Shimano Hollowtech II crank with a BB386 standard frame. It is a thread fit BB that has achieved weight reduction by making the main body made of resin. The part that is press-fitted into the frame is specially processed to not only be press-fitted with less force (10-12N/m) than before, but also to reduce noise. *This product is an officially imported product with a quality guarantee, so you can use it with confidence.
