FastTT - Mounting Spacers - 20mm

Universal Interlocking Aluminium Spacers

Our CNC-machined interlocking aluminium spacers are designed for universal compatibility, fitting most bikes that use M5 or M6 screw threads. They accommodate a wide range of bolt patterns from 15 mm up to 38 mm bolt-hole centres.

Available Heights:

- 5 mm

- 10 mm

- 20 mm

*Each pack includes two spacers of the selected height.

For best performance, we recommend installing a bridge, BTA bracket, or adapter plate with all spacer kits to ensure maximum stability.
Please verify the dimensions and bolt pattern on your bike before ordering to confirm compatibility.

Important Mounting Information

- Our spacers support a maximum bolt-center distance of 38 mm.

- If your base bar has bolt centers larger than 38 mm, you must use your original spacers.

- If your bolt centers are 38 mm or smaller, you can use FastTT spacers.

- When fitting FastTT spacers or adjustable angled risers directly to the base-bar pedestals, you’ll need our optional interface shims.

- If you fit your original spacers directly to the base bar, interface shims are not required.
