WizWheels 406 rim erd.

edited April 2011 in Accessories
What is the effective rim diameter of the standard silver 20" (406) wheel (like the ones that come on the Rover)? I need this info for a spoke length calculator (I am rebuilding a wheel). I know I could measure it, but that's a hassle and I figured it was a known spec. Thanks.


  • The ERD of our single walled rim is 395mm.

  • Thanks Kelli! That keeps me from having to disassemble the wheel any earlier than necessary. I can order my spokes and keep riding until they arrive. Much appreciated.
