21 Speed Hybrid/ Road bike with a medium sized (45 cm) lightweight aluminum frame and upgraded components throughout the bike. Upgrades: I replaced the stock rear derailleur with a better one that works more smoothly and doesn't jam up, as well as the brake levers and shifters; the seat & seat post; and the brakes also were replaced at the same time and oil added to the brake line to prevent rust in the future. The wheelset is an upgraded version of the original as well. The rims are a bit stronger and the hubs a bit lighter and smoother. Has been tuned recently and is ready for use. 280$ Pick up in little italy
