Dennis, thanks again for the Brigdestone frame and parts. (ed: see # 379) Here's the final product with a 45 x 18 drive on the freewheeling hub. Used the fixed innovations site and got a useable gear combo without the need for a tensioner. Harris cyclery sells tall profile chairings with 130 and 110 BCD for reasonable in most sizes, made the combo work. I did have to use a "half-link" on the chain to work the final drive, but turned out very clean. Look for Sue burning around town on the "Green Hornet", former Kabuki by Brigdestone.
Thanks again. Rob -
