No cobbles in my hood but plenty of buckled asphalt, cracks, gravel, and dirt stretches. The Domane dishes out confidence. The system works. I haven't had any problems with mine, nor have I heard of any. Test ride several bikes, including a Domane, and compare the ride for yourself. I rented a 5 series for a few days ( loved it) and ended up buying a 6 series with Di2 (really love it).
