Since Jess’s Cross-Check was singled, we have a set of bar-end shifters, front and rear derailleurs, and a rear wheel left over. Also, I’ve been feeling the need for a good geared road bike. Hmm, Shifters, derailleurs, rear wheel. Just need a few more parts for a full bike. Let’s see… just need a frame and a front wheel. Oh, and headset, stem, bars, brakes, levers, seatpost, … Darn, that’s most of a bike, isn’t it?
