Pick the height extension you need with either of the options on offer. 5, 10, or 20mm spacer.
Used for compatibility issues when:
- The Shim is too short to reach the headset
- The fork hits the SCS system so the compression bolt cannot be tightened
- Put these over your headset on the fork and create the space needed
Measurements:
- 1.10″ (28mm) inner diameter
