Mounting a Simucube 2 Quick Release Adapter on Your Wheel

Quick answer

Mount the Simucube 2 Quick Release Adapter by removing the original quick release, selecting your hub or extension, and securing it with the included hardware using one of the three common mounting patterns.

Mounting steps

1. Remove the existing quick release: Unplug the wheel from the base and use the appropriate tool to unscrew the original SC2 quick release from the wheel side. Keep the screws for potential reuse. Common mistake: Forgetting to unplug the wheel first, which can strain the cable. Always disconnect before unscrewing.
2. Select your hub or extension: Decide whether you want to attach a new hub, an extension, or a different quick release. Ensure the mounting holes on your chosen component match one of the three patterns: 6 x 50.8 mm, 6 x 50.2 mm, or 6 x 70 mm. Checkpoint: If your component uses a pattern not listed, the adapter won't fit. Measure the hole spacing before proceeding.
3. Align and attach the adapter: Place the adapter against the back of your chosen hub or extension, aligning the holes. Insert the included screws and tighten them evenly in a star pattern. Do not overtighten. Common mistake: Overtightening can strip the threads or warp the adapter. Use hand-tight plus a quarter turn with a wrench.
4. Mount the assembly to the wheel base: Position the adapter assembly onto the wheel base's mounting plate. Secure it using the original screws or the ones provided, tightening in a cross pattern. Checkpoint: Ensure the adapter sits flush against the wheel base. A gap indicates misalignment or a wrong mounting pattern.
5. Test the connection: Reconnect the wheel to the base and test the quick release function. Verify that the wheel locks securely and releases smoothly. Final check: If the wheel wobbles or feels loose, recheck screw tightness and pattern alignment. Do not race until it feels solid.
