How to measure Effective Rim Diameter, or ERD YouTube
This video describes the method that I use to measure the ERD or Effective Rim Diameter of a bicycle rim. You will need a tape measure with millimetres, two.

Use the charts below to reference important wheel building information such as Effective Rim Diameter (ERD) and Maximum Spoke Tension. You can also use this chart to easily compare different models' weight and overall dimensions. *Important note regarding ERD or Effective Rim Diameter vs. Spoke Bed Diameter*
How To Measure Rim Diameter and Hub Dimensions to Calculate the Perfect
What is the effective rim diameter (ERD)? Effective rim diameter is the maximum distance that spokes need to bridge going from one end of the rim to another (on the opposite side, just like when measuring a circle's diameter).

Effective Rim Diameter (ERD) is the diameter on which you want the ends of the spokes to lie, we calculate from the top point of the nipple. The corresponding equation and a representative figure for that definition are as follows: ERD = A + 2B If you want to measure your own rim (recommended, just to be sure), then follow these instructions:--1.

Effective Rim Diameter (ERD) is the diameter on which you want the ends of the spokes to lie. Most people prefer it near the end of the spoke nipple. The corresponding equation and a representative figure for that definition are as follows: ERD = A + 2B

Excerpt from a complete chapter in Master Wheel Building II that thoroughly explains how to measure Effective Rim Diameter (ERD) which is an essential step i.
Measuring Effective Rim Diameter Park Tool
ERD, short for Effective Rim Diameter, is the rim diameter measured at the nipple seats in the spoke holes, plus the thickness of the two nipple heads. It's used to calculate spoke length when preparing to build a wheel. More Ways to Get Contact: Leave a Message.

What is the rim ERD (effective rim diameter)? 27.5 581mm including required spoke washers. (579mm without) 29 619mm including required spoke washers. (617mm without) When making spoke length calculations, we recommend rounding up any fractions of a millimeter to the next highest millimeter to ensure that the base of the spoke nipple is properly.

Enter one set of hub and rim dimensions and SpocalcExpress gives you the spoke length for radial, 1, 2, 3, 4, and any other cross of your choice. Great for Quicksheet on your Palm. What is Spocalc? Spocalc is a free Excel spreadsheet I made that calculates spoke lengths for wire-spoked wheels.
Measuring Effective Rim Diameter Park Tool
A big part of determining the correct spoke length is using the correct "Effective Rim Diameter" (ERD), a concept that is reviewed in this article. Spoke length that is either too long or too short will be problematic. Too long, and the spokes protrude past the end of the nipple.
What is the Effective Rim Diameter? And how do you measure it
Effective Rim Diameter (ERD) is the dimension you type into the form field for ERD. Of all the dimensions you actually might measure, ERD is the most critical dimension affecting spoke length, so it makes sense to measure it a few times at different places around the rim.

Measuring the rim effective diameter. Hope it becomes clear to you from the graphics above that ERD is not the diameter where the tire fits in the rim, nor is it the inner diameter of the rim hoop. ERD is defined as the diameter of the circle through the ends of the spokes. Given the ideal spoke length, spoke should be threaded to the end of.
