ERD Rim Rods with Clips - 700mm

BSC Tools ERD Rim Rods with Clips - 700mm take the guesswork out of wheel building. Designed for precision and simplicity, these stainless steel rods let wheel builders quickly and accurately determine Effective Rim Diameter (ERD) without relying on math or charts. Whether you’re building your first wheel or tuning up your pro-level setup, these rods deliver consistent, repeatable results every time.

Each set includes two 350mm rods—one marked with a ruler scale from 700mm down to 400mm and one plain—making them ideal for measuring most 700c and 650c rims, including offset designs. The chamfered ends fit snugly into nipple eyelets for reliable contact points, while the included clips hold the rods securely together so you can focus on the reading, not the alignment.

Key features:

• Accurately measures Effective Rim Diameter (ERD) without calculations

Durable, simple, and made for repeat use, the BSC Tools ERD Rim Rods with Clips are an essential tool for anyone serious about building perfectly tensioned, precisely sized wheels.
