- This video explains firstly what Effective Rim Diameter is NOT. It is NOT a religion, nor is it a industry standard or specification owned by any one person, group or organization. Effective Rim Diameter is a reference and is dynamic - NOT static.
"The distance from the end of one spoke, to the end of the opposing spoke at 180 degrees, in an already built and functional bicycle, is the Effective Rim Diameter for that already built and functional bicycle wheel."
Furthermore, anyone contesting this definition is contradicting themselves if they use the "Rim Rod + Caliper" method for guesstimating ERDs.
This video explains how nipple type, nipple size, and nipple threading and spoke threading changes make Effective Rim Diameter a dynamic reference.
This video also explains why it is important to not just publish ERDs, but to also include a short description of how it was that you obtained the ERDs that you publish.
