SPD ERD Sticks

To accurately measure ERD of any rim.

Place the sticks opposite one another in the rim and use a good quality spoke ruler or steel rule to measure the gap.

Each stick is 150mm. ERD = sum of the sticks plus the measurement.

If the gap is 280mm ERD = 300 + 280mm = 580mm.

Shipped with 14mm nipples as standard, if you require double square, squorx Etc drop me a line.
