• Correct me if I’m wrong. I’ve written to sapim but didn’t get a reply. If using their MS washers, should I add 1mm to ERD, when calculating spoke lentgh?
    I’ve found a technical drawing on some of their distributors’ site.

  • I think I would add 2mm, or have done in the past.

    What’s best is actually measuring the ERD while using the washers, if you can.

  • Yep, I’m gonna order the washers and nipples first, then remeasure and order the spokes afterwards. Was just trying to avoid shipping since everything is from elsewhere.
    Apropos, I’m glad I measured erd beforehand, since it’s 5mm off of the manufacturer’s number.
