I've had my Roebling for around six months now. It's been a good experience. The key use for me is for utility rides, but sometimes for athletic rides too. Everything has really checked out with it. Brakes, gears, tires, etc. The layout with the bike tends to support my efficient ride style, where I want the speed I can get from it, where I'm tucked into it, and am able to respond to any traffic problems. I did have one flat early on with it and patched it. For myself, while the tires are good, and are the same size compared to what I sized down to on my Marin hybrid (35C) I'm planning on sizing down to 32C with this for the speed and city streets. I did have an issue with the left rear brake arm locking on me, but when I removed the arm, it was obviously related to too much crud built up or left. Cleaned and lubed and it straightened out for me. The other three haven't done that yet, but now I know the take down for those. The 29 pound weight is reasonable and three lbs. under what the Marin weighs, and five over what my steel State road bike weighs.
