Thanks. Jones said he'd email me that OW of the chainstays at the end-of-cranks position but never did. But research indicates that current models won't give me the required 160 mm or lower Q and, in fact, after much measurement and calculation the arithmetical evidence convinced me that my quadruple goals -- 700C with true 3" width, 160 mm max Q, stays of non-absured length, and sufficient air between outside knobs and inside chainstays -- would be possible only with very carefully massaged plate yoke between bb and chainstays. In the event, for now, I decided that I don't need the hassle of another custom, and I chose instead to get a fatter (compared to current 50 mm Soma SV) sandy path wheelset for the Matthews #1.
As to the Gus, I'm sure it won't take a 622X76 tire, but I still wonder (a) how fat a tire will it take and, (b) what the *minimum *Q is.
