Update to Damon Rinard’s Spocalc Spoke calculator — new advice on fatbikes and hub motors, more spoke calculators for mobile devices added to the list at the bottom of the page, correction of a minor math error (display of bracing angle for radial spoking).

Spoking for large hubs, improved
The article on special spoking patterns for use with extra-large hubs (for example, electric bicycle hub motors) has been improved with patterns which avoid twisting the hub shell for two of the hub and rim combinations. The article includes all the information needed to use Damon Rinard’s Spocalc (also on the site) to calculate spoke lengths for these patterns.
Check spoke tension by ear when building a wheel
Check the level of spoke tension by ear — unless you are tone deaf, a musical pitch reference (pitch pipe, tuning fork, smartphone app etc.) is all you need to tell whether you have brought spokes up to the appropriate level of tension when building a wheel. It’s faster than using a tensiometer!
Spocalc revised
The page for Damon Rinard’s spoke calculator has been revised, with an updated list of online spoke calculators, several comments and links, and better formatting. Now also includes links to spoke-calculator apps for iOS and Android smartphones!
