Measuring Hubs & ERD

Repair & Tech Info - Featured Tech Articles

The measurement you aquire in the process can be used in conjunction with the DT-Swiss spoke calculator and the spoke calculator provided by Damon Rinard.  The other option is to take these measurements and email them to Bikeman with the following information.  We will need to know the number of holes your hub has and the lacing or number of crosses you would like the spokes to have.

We recommend using a few tools to help you with this process. A set of metric calipers will be enough to take the measurements from your hub. Precise measurement of ERD (Effective Rim Diameter) requires a rim measuring kit, like one from Wheelsmith . Bikeman offers both for sale.  The DT kit is a bit more cumbersome to use but is much cheaper and comes with a set of calipers. Click on the Products below to get details. Damon Rinards spoke calculations web site offers some alternatives to the rim measuring kits. Follow the instructions carefully if you go that route.
