Just finished a pretty much total rebuild of my 2013 Quick SL3. I liked it just fine to begin with, but I enjoy shop-monkeying around and thought I'd see if I could turn it into the uber-hybrid: better mechanicals, more robust, more comfortable, yet lighter/faster. And, oh yeah; prettier. Here is the final (well, almost - I do have a new stem coming ) result - hadn't even wiped my greasy paw prints off it yet. Bike now weighs just a hair over 22 lbs, yet wheels/tires are far more rugged and comfortable than stock.
