When I was racing bicycles in the early 1970s I built my own wheels. Until 1976 when I was trying to adjust the dish in a new rear wheel I was builiding when I warped the rim. I said "Never again!" Since then I've had others build my wheels. Until now. I found a number of wheel building resources on the web that have changed my mind. I need new wheels for my "new" Schwinn Mark IV.
Measuring the effective rim diameter in order to determine spoke length. 3 cross, 36 holes. I'm using The Professional Guide to Wheel Building for instructions. Wheel Fanatyk a great resource for wheel building tools and spokes.
