BSC ERD Tool - Short (500 mm)

The BSC ERD (Effective Rim Diameter) tool is constructed of durable 304 stainless steel. Measurement markings are laser-etched along the length of one rod, eliminating the need for manual measurement. The head of each rod has a short profile to allow it to fit inside offset rim profiles and directionally drilled spoke holes.

The short version of the BSC ERD rod is exactly 250 mm in length from the chamfered head to the tip of rod and will measure rims with an internal diameter from 270 to 500 mm.

A detailed description of how to use the BSC ERD tool to measure ERD is available on our Blog here.

This product includes two rods and two Meuller BU-45 clips.

Please note that the BSC ERD tool is not designed for rims that use internal nipples.
