Had a set of wheels built at my local shop. Ordered the track hub and rims, he took measurements and I ordered up the cut he said to. Got 'em laced up and what do you know? the spokes are a teeny bit too long and there is no more thread to tighten them up so needless to say, I'm a little f'ed here until I fix it right. Can anybody tell me exactly where do I measure the spoke length? I imagine it would be from the center of the hub hole to some magical poiint at the rim. Since the wheels are already laced it shouldn't be too difficult to take that measurement myself.
