Are you ready to SHRED!? Start shredding in no time with the Shred Sled, the next generation caster board. The first 4-wheel, dual-deck inline caster board, the Shred Sled makes it smoother and easier to start carving up the streets. How it works: Shred Sled's two boards and flexible connector allow both boards to rotate around the vertical and horizontal axes so it's easy to maneuver the board. The best part is you don't even have to push off! For better control and traction, each deck has a grip surface to maximize traction and stability while the concave decks make for better foot control. The 4 x 80mm polyurethane wheels and ABEC-5 bearings are smoother and stronger than standard hardware and unlike other boards, rarely need to be replaced. Riding the Shred Sled feels like a combination of snowboarding, skateboarding and surfing and it's much easier to control than older 2-wheel generation boards. Great for strengthening the legs and waist muscles, Shred Sled encourages kids to get off the couch and get active outdoors. Available in black, blue or red. Weight: 8.7 lbs; Dimensions: 9.055"W x 32.87"L x 4.72". Be sure to wear a helmet and safety gear when using the Shred Sled.
