ATS Shim & Top Cap

ATS Shims with Top Caps are available to be purchased separately.

Choose from either black or silver. We keep two different lengths in stock:

80 mm ATS Shim = 40 mm of adjustability

100 mm ATS Shim = 65 mm of adjustability

To find the length you need, measure your steer tube.

Remember that the ATS Shim should extend only 2-3 mm above the steer tube.

It is NOT intended to be a Steer tube extender.
