- CNC machined from solid 6061 aluminium to exact tolerances
- Stiffer than any original equipment hanger which improves shifting performance
- Still breaks before your frame does to perform its main function
- Direct replacement for original equipment with guaranteed fit
- Black anodised for extra scratch and damage resistance
- Laser etched for easy part identification
- Note: WMD303 is for M12x1 single lead threaded axles. Not for use with the stock Speed Release axle found on the 2019+ SystemSix, which uses a double lead thread. Please order WMD399 for double lead thread
