Well, so far I haven't done so well. The seat, stem and bars were a breeze but I gave up on all the darned cables. Putting an adjustable stem and 5" riser bars on my wife's 18 year old hybrid Schwinn was more work than I had imagined. There just wasn't enough cable to use. I've sent the bike to my local shop as I just don't want to have issues with braking or shifting (21spd) when we're on vacation next week. The good thing though is that she's happy with the new cushy seat and more upright riding position. Next time I'm going to start with an easier bike.
