Now you can carry that extra gear on your touring/camping/road trips. The CycleSling is for people who need a little extra room for that sleeping bag, tent, beach chair, fishing rods or whatever! Easy to install, only takes minutes to set-up, and NO tools needed. Strong nylon straps secure the "Slings" to the side rails and secure your gear too. The CycleSling package is a set of 4 "Slings" with straps, 2 attach to each side of your bike. Recommended max weight is 15 lbs. per side. CycleSLing is made of lightweight aluminum that is powder coated black with rubber coating to protect the rails. Looks clean on your bike, even when empty.
