ROADUNO It's the most useful, and fun non-derailer'd bicycle (or frame) we can imagine. We named it Roaduno to emphasize that it's for roads. Smoothish paths, no problem if you have the skills for them--like the Homer in that way. The sidepull brakes should tell you it's not a mountain bike. • The rear hub is a flip-flop, but we recommend using only the freewheel side of it. We suggest you don't ride fixed (uncoastable) cogs; too risky. You CAN put another single-speed freewheel on the left side, but if that appeals to you, why not just get a White Industires two-speed freewheel and keep it all on the right side? We stock them. It's as versatile and as customizable as a derailer-less road bike can be: • Fits tires to 45mm (43mm with a fender). Any tire bigger than 40mm requires some deflation to install and remove, but that was no reason to not design in clearance for bigger tires. • • Braze-ons for racks (and fenders), and of course has a kickstand plate. • • • Has a front shifter braze-on, and a derailer tab integrated with the rear dropout, so you can easily mount either a commercial chain tension or any derailer (as a chain tensioner) • • • • An in-the-box COMPLETE comes with a 38t big ring and a 26t small ring and a 16t cog on a flip-flop hub. To access the 26t ring (to make it a a 2x1), add a shifter and front and rear derailer/chain tensioner. To make a 3x1, get rid of the chainring guard and mounting a triple crank in its place. If you buy a frame we can build it up with any of a dozen or more chainring and cog combos. Or you can do that yourself. We have stock crank combos of 34x24, 38x24, 42x28, and 44x34x24. We stock single-speed freewheels 15 to 22t (no 21t), and White Industries DOS (2-speed) freewheels in a few combinations. The Roaduno is a mad scientist's dream experiment. The stock 38 x 16 gearing works well for most riders on flat roads to easy hiills. Frame & fork: Our standard super-quality, butted CrMo tubing of our own design. Our own lugs, fork crown, dropouts. Same painter as always, same lug-fill cream details, nice metal head badge, excellent graphics, etc. The fork crown is the same we use on the Appaloosa. Sizes: 47.5 (650B), and 51, 54.5, 58, 61.5. (
