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 adjust the calculations automatically.

Warning: The calculator allows combinations of hubs and rims that may not be compatible. Check the hole count, braking system, axle size, asymmetrical rim installation direction, and product availability before purchasing or assembling.

*Front-side naming follows disc-brake hub orientation. For rim-brake hubs or symmetrical hubs, still match the physical flange sides during assembly. Recommendation markers indicate common configurations based on the spoke count; they are not mandatory requirements for every hub and rim combination.

Important: The main figure shows the nominal size rounded to the nearest 1 mm. The geometric calculation result before rounding is displayed in smaller text to 2 decimal places. The wheelbuilder still needs to determine the final length based on the available spokes, nipple length, ERD tolerance, measurement method, and target spoke-end position. Verify with the actual components before placing a large order.
