Spoke Length Calculator

WheelCalc is a spoke length calculator for wheel builders cyclists and bicycle mechanics. Calculates lengths of spokes from hub and rim measurements.

• WheelCalc is a program for calculating spoke lengths when building bicycle wheels
• Any spoke crossing patterns possible including wheels with different cross patterns on either side of the wheel.
• WheelCalc is an accurate and inexpensive tool to calculate the spoke lengths for bicycle wheels
• WheelCalc calculates allowances for spoke stretch and wheel rim compression.
• Calculates stress and strain on spokes for given tension
• Calculates differences in tension for dished rear wheels
• Build wheels with unequal hub flange diameters and even flange hole diameters
• Build wheels with different spoke diameters, and even elasticity on either side of wheel.
• WheelCalc incorporates a context sensitive help system to explain all of the required measurements.
• Not limited to bicycles: You can also work out spoke lengths for just about any size of spoked wheel including Penny Farthings, and vintage sports cars
• Allows completed wheels to be saved as files for later use
• Spoke length explorer provided as visual check if spokes will bind (i.e. building with too many spoke crossings)
• Spoke length explorer also has funky psychedelic bicycle wheel display!
• Spoke details are coloured differently for left and right sides of wheel - If you don't like the default colour scheme you can change it.
