The L2.1 deck is identical to the L3.1 which won pretty much every major street jam so far this year. The difference is in the neck which is extruded and welded. Unchanged is the amazing grinding ability, the perfect balance and light weight. It also comes with the super strong U-shaped weld design which barely cuts into the deck and significantly increases the welding area. Other features are a machined headset opening for a precise fit, high tensile Chromoly axle bolt, a completely flat bottom and integrated grind rails which reduce friction and increase the grinding speed. The deck is fully integrated and made of the highest grade heat-treated 6061 T6 aluminum. Slightly rounded side walls provide a smooth feel in finger whips and a curved stainless steel flex brake prevents flat spots on your wheel.
