Biolite 3 Core Abrupt Continuous Rocker Variable Edge Design Boneline Grab Rail Cupped Tail Rail The KRUZR-GLS has more surface area than any other board but has been shaped to maintain a lively feel with a minimum thickness profile. More comfy than previous shapes, Rusty feels all ride styles and ability levels will enjoy this new shape which will surely suit riders in the 200+lbs range. Aaron brought new features like the Boneline Grab Rail and Cupped Tail Rail design allowing the wider board to sit deep in the water for a solid edge hold on approach. The Molded Landing Feature is included while the overall base design is simpler, delivering that cruisy flowy feel between tricks and carving the wake. Paired with the Team X closed toe binding, this Kruzr setup will take your wakeboarding to new levels.
