I am probably going to leave the seat on the QX100 at 45 degrees, and use this bike for casual around-town riding. As far as learning new skills, I took up bass guitar six years ago, and have been using inline skates for several years now, and now, riding a bike with a moving bottom bracket. If I can get a frameset, I could raid my DF road bike for the components. There is something to be said for being able to smoke DF riders. Biggest fear I have with skinnier tires is getting caught in a crack in the pavement. It isn't easy finding a used Vendetta, though. My QX100 is the only Cruzbike I have ever seen in real life. Right now I have a seat post rack on the back. Is tiller steering all right, because I would have to put a longer stem to be able to reach the bars if I try to radically recline the seat? I have rather short arms and can just comfortably reach the bars with seat at 45 degrees. After more miles on bike, I do plan to move seat back to a slightly lower position. There is a thread on a guy who created what he called a "Verdetta" out of a Quest bike.
