Not that bad. 2 flats in 4 years. Easy fix there. Busted a frame at the seat tube and BB junction with 10 miles left in the commute. Amazing what 6 ft of duct tape and 2 zip ties will fix. Snapped the rear der. cable. A stick and some zip ties to put it in one gear for the remainder of the ride. Just be prepared with some basic tools and supplies.
