BB Spacer

Adjust your chainline with one of these spacers. Place them under the driveside of your SKF or cup-and-cone bottom bracket to move the spindle to the right and provide extra clearance for triple cranks. Can also be used as freewheel spacer. Aluminum (1, 2, 4 mm); stainless steel (0.6 mm).

Note: Avoid stacking several spacers, as the BB cup may loosen.
Use one thicker spacer instead.
