Arkel has designed the most aerodynamic trunk bag on the market. One look and you'll be hooked. It's sleek, uncluttered and aerodynamic. The TailRider is fully insulated, has a huge opening, many internal pockets and a divider to keep the contents from shifting around. Waterproof zippers keep the rain out, but for longer rides the TailRider has an integrated rain cover. A built-in expansion bellow expands for more carrying capacity when needed. Wrap it all up with lots of safety features, including a blinker light strap built right... the ultimate trunk bag for short or long rides!
When used with the Arkel Randonneur rack the Brompton can fold fully with rack and pack attached (see photos)
Minimum Rack width required: 3.15" or 80 mm
