OBTW:
I fired off an E-Mail to Buchanan Spoke and Rim in California to find out what spokes I'll need to lace up a 21 inch DID alloy front rim on the original F7 front hub on the dirt machine. I'm after a set of plain jane heavy guage stainless spokes and nipples so they don't rust and crud up, and for strength.
You've heard my theories about wheel weight and fuel economy - the method also works for speed and handling. I'm going to lace up a set of wheels for this bike that will turn it into a totally different creature!!!
