Topeak Explorer Tubular Rack w/Disc Mounts and Spring

Topeak's Explorer Tubular Rack is a great add-on for carrying a trunk bag, pannier or anything else you want to strap on. It's made of tubular aluminum, fits most bikes with disc brakes, and has a center strip that acts like a short fender, too. Plus, it comes with a spring that folds up to clamp securely onto books, magazines and other thin objects.
