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!
