What is rims ERD? ERD (Effective Rim Diameter) is important data for calculating the length of the spoke. ERD refers to the maximum distance of the spoke from one end of the rim to the other end. Next, we discuss how to calculate ERD. As shown in the picture below, ERD=nipple length*2 + the length between 2 opposite nipple seats of spoke holes. So the length of the nipple will affect the ERD, w...
