What is the maximum thickness of the bottom bracket washer to avoid the collision with the chain stay? I measured my frame and I need about 5mm of extra clearance.
Hello, may I ask how long your bottom bracket is? If your bottom bracket is 68mm long, we happen to have two washers with an outer diameter of 41mm, inner diameter of 35mm, and a thickness of 2.5mm. These washers were originally meant for bikes with a 73mm bottom bracket. If your bike's bottom bracket length is 68mm, using these two washers will move the crankset and crankset cover outward by 5mm, preventing the crankset from hitting the frame. However, you need to confirm if simply adding 5mm is enough. It would be best if you could take a photo to show us the gap between the crankset and the rear triangle so we can make a better assessment.
Can a bottom bracket washer be added between the stiffening plate and the bottom bracket shell?
