All our Universal wheels are designed with 10mm axles to ensure compatibility with both 10mm and 9mm dropouts. For a proper fit with 9mm dropouts, we recommend filing the axle flats by 0.5mm on each side. This is a straightforward adjustment when done with the appropriate tools.
Key Points:
- Warranty-Friendly: This adjustment will not void your customer's warranty.
- Detailed Guide: We’ve created a step-by-step axle filing tutorial for your convenience. Watch it here: Axle Filing Tutorial.
- Important Note: Only file the Swytch Kit Motor Axle—never modify the bike forks.
By following this guide, you can ensure a smooth and secure installation for your Swytch Kit.
