The following are dimensions for building a wheel with a Lefty hub:
- Both a SuperMax or Lefty wheel hub can be used with the SuperMax. The wheel hub must be matched with the correct brake adapter.
- The hub cap is a left-hand thread. It retains the axle bolt assembly and should only be removed when replacing the bearings or axle bolt parts, not when removing the wheel.
- The axle bolt is a right hand (normal) thread. To install or remove the wheel, insert a 5mm allen key. Turn it clockwise to install the wheel and counter-clockwise to remove the wheel.
- The Lefty hubcap is LEFT-hand thread. Use a Shimano TL-FW30 tool to install.
