Spoke Length Calculator

Calculate estimated spoke lengths for Strummer or OXO J-Bend and straight-pull hubs. Select a hub and rim; the calculator will automatically adjust the calculation.

Warning: The calculator allows combinations of hubs and rims that may not be compatible. Check the hole count, brake system, axle size, orientation of asymmetrical rims, and product availability before purchasing or assembly.

*Front-side naming follows the disc-brake hub orientation. For rim-brake hubs or symmetrical hubs, match the physical flange sides during assembly. The recommendation indicator shows a common configuration based on the spoke count; it is not mandatory for every hub and rim combination.

Important: The primary figure shows the nominal size rounded to the nearest 1 mm. The geometric calculation before rounding is shown in small text to 2 decimal places. The wheelbuilder still needs to determine the final length based on available spokes, nipple length, ERD tolerance, measurement method, and target spoke tip position. Verify with the actual components before ordering in large quantities.
