The Bikesmart Rack Trunk 1.0 Bag is a versatile piece of cycling luggage that is equally at home commuting to and from work, on day trips, or even on multiday touring adventures. This rear rack-mounted trunk has a large main compartment with two smaller, zipped interior pockets to keep things organized, as well as two exterior pockets. It attaches to your rack with a durable, grippy hook-and-loop closure, and also features a convenient shoulder strap, so you can take it with you when you park your bike. Plus, a reflective strip enhances your visibility, while doubling as an ideal place to clip a rear light.
