I'm about to start my first wheelbuild. I disassembled the existing wheels and kept all the spokes in 3 labeled bundles from the front wheel, rear drive side, and rear non-drive side.
I have measured the existing spokes again and again to try to determine the size spokes I need to order, and I keep getting 308mm... on all of them. Whether they're from the front, or either rear side. This is from a wheel on an old 10 speed with a 5 speed freewheel. (27" Fiamme yellow clincher rims, large flange Campagnolo "nuovo tipo" hubs)
Shouldn't the rear wheel spokes be different on the different sides due to the dish? I'm a little confused here. Thanks for any light you can shed on this.
