ATS Shim & Top Cap

Extra ATS Shims and Top Caps are also available to be purchased separately. Choose from either black or silver. We keep three different lengths in stock:

80 mm ATS Shim = 40 mm of adjustability

85 mm ATS  Shim = 45 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.
