Having your wheels securely attached to your bike is paramount for safety and functionality. You can rest easy and relax in the knowledge that your bike & wheels are safe and secure with the Curve Relaxle Thru-axles! 

The Relaxle functions in exactly the same way as any axle would but with a few extra features in case of wear, emergency or mounting options. There is only one way to tighten and loosen most axles. The Curve Relaxle gives you four options, giving you peace of mind in remote areas.



  • 6 mm allen key broach on both sides of the axle - just in case you round out one side
  • 15 mm hex head for additional mounting/dismounting options - just in case you have destroyed both 6 mm removal options
  • M5 Thread in the 6 mm allen key broach for attaching racks or fenders


The Relaxle is compatible with all our current frame and fork options. See the chart below to check the sizing and compatibility of your frame and fork.
