16 Speed, Aluminum Frame, Hydraulic Disc Brakes, Commuter, Large frame. Purchased about a week ago. works perfectly. Using for work and school commute but the frame is too large for me. Also accepting trades if you've got a lighter road bike with a smaller frame. I've added a back rack as well as a small handlebar mirror but I also have the original handlebar cap if you want to remove it. Not stolen, Proof of purchase upon request.
