Calculateur de taille des rayons pour roues Strummer
STRUMMER PRODUCT TOOLS
Spoke Length Calculator
Calculate the estimated spoke length for J-Bend and straight-pull Strummer or OXO hubs. Select a hub and rim; the calculator will automatically adjust the calculation.
Attention : The calculator allows combinations of hubs and rims that may not be compatible. Check the number of holes, brake system, axle size, installation direction of asymmetrical rims, and product availability before purchasing or assembling.

*Front-side naming follows the orientation of a disc-brake hub. For rim-brake or symmetrical hubs, still match the physical flange side during assembly. Recommendation markers indicate common configurations based on the number of spokes; they are not mandatory requirements for every hub and rim combination.
Important : the main figure indicates 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 must still 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 ordering in large quantities.
