Sometimes I just wonder what goes on in peoples’ heads. Take a look at Trek’s new single-speed. A 26″ rear wheel and a 29″ front wheel — why carry one spare tube, when you can carry two? Not to mention that fork, is that a triple crown, on a single-speed? Leave the hare-brained ideas to the autism squad over at Cannondale, world renowned for solving non-existent problems. They, at least, can fall back on their cool schwag.
