The Voil 3-Pin Cable Traverse Riser features a newly designed 10mm shim and a 18mm heel pad. The 3 ramp angle in the binding shim helps reduces rocker launch to keep you off your tippy toes and the dual height, 55mm and 75mm climbing bars help prevent your calf muscles from cramping on the way up. Also compatible with our HD Mountaineer 3-Pin Telemark Binding.
