Welcome to the 6th,7th, 8th, or more annual NYCC wheelbuilding class. Come with a rim, a hub (with the same number of spoke holes as are in the rim, please), and correctly sized spokes.
Leave approx. 3 1/2 hrs. later with your own perfectly laced, perfectly trued, perfectly tensioned wheel: you'll have done it all yourself.
Depending on turnout, if you only want to learn how to true, that may be do-able.
Class begins 11AM, Saturday, Feb. 3 and is at Second Ave. and 63rd Street.
