Stage 5 Duraflex Base: The ST Stage 5 Base is perfect for All Mountain / Freeride based riders looking for serious bang for the buck. Canted and bombproof, the ST blows away everything in its class. Multi-Density Thermoformed Eva Bushings: Multi-Density Thermoformed Bushings sustain their function season after season - unlike competitors who use urethane, rubber or other materials that change color and become brittle over time. Extruded 3D Aluminum Heelcups: The rigidity and strength of Extruded Aluminum acts like a roll cage on a race car - stiffening the entire chassis. The male/female connection with the base provides seamless response. ST Symmetrical Highbacks: Symmetrical modern fitting ST Highbacks feature a multi-layered nylon design that is ideal for all around heelside support and control. Bone Out Ankle Straps: Light as a feather and super comfy, Bone Out straps feature a 3D Symmetric design that eliminates foot pain across the top of the foot. Aluminum Ratchets: Fast in and fast out - this new mechanism combined with union aluminum is superior to any binding ratchet on the market - with the exception of union magnesium.

Baseplate Stiffness: Medium Flex 6/10 Highback Stiffness: Medium Flex 5/10 Disk Type: Universal Disk w/ 4x4, 4x2, Channel
