bottom bracket & cog spacers

$ 3.00

Items that are in stock can be added to cart.

These handy aluminum spacers fit between the frame and drive-side bottom bracket cup (cup must have flange or lip) and can be used to dial in your chainline or to overcome drive side crank arm clearance issues.

They can also be used to increase the chainline measurement of a cog or freewheel, should you ever really feel a weird need to futz around with that.

DO NOT put a spacer between your cog and lockring, as this will reduce the number of lockring threads engaged and decrease the friction needed to properly secure these components.

All this being said, BE CAREFUL WITH THESE. Using them incorrectly can seriously damage your bike and then you'll be all bummed out.

Sold individually.


⚠️ Not recommended for use on Sram GXP bottom brackets.

Yes, we know Sram Omniums have clearance problems on some frames. Unless you're a hack and want to ruin your bottom bracket bearings, adding spacers is not the solution.

• 1, 1.5 or 2mm thickness
