An offline bicycle wheel calculator that updates spoke lengths as you change hub, rim, crossing, and dish measurements.

Landing page captured for the 2026-09-15 issue.

Field notes

The calculator models each wheel side separately from ERD, flange PCD, center-to-flange distance, hole count, and crossing, then exposes spoke lengths, dish offset, and the left-right difference. Its catalog includes 12 hubs and 12 rims, with seeded examples ranging from commuter 700c and gravel dynamo wheels to cargo 26-inch 4x builds. Rounding can be exact, half-millimetre, or whole-millimetre, and saved kits retain gauge, nipples, and notes locally.
