Rocker Type

AmpTek All-Mountain Rocker – AmpTek All-Mountain features softer tips and a stiffer waist with 50% camber between the feet for powerful edge grip and stability, and 50% rocker at the tip and tail and forgiveness for effortless freeride versatility.

Flex

Flex Rating: 5 (1 Soft - 10 Stiff) – Moderately soft flex for a blend of accessibility and freestyle performance.

Directional All-Mountain Flex – Rossignol's Directional All-Mountain Flex profile is stiff under the back foot for control with a stiff waist for stability at high speed. A softer flex under the front foot delivers easier turns and maneuverability.

Shape

RadCut – A traditional sidecut between the inserts fuses with multiple reverse sidecuts toward the tip and tail, providing real time sidecut adjustment to the ride, ie. longer when faster, shorter when slower, and delivering the perfect cut at all times. RadCut is offered in multiple versions, each tailored for individual riding styles. More aggressive sidecut blends deliver quicker, livelier turns, while smoother sidecuts offer a more fluid, relaxed ride.

Core

Wood CBF – A single type of wood that's mixed with Basalt and Kevlar fibers in its center for added comfort and punch between the feet with smooth edge-to-edge transitions.

Laminates

Basalt – Stronger and lighter in weight than fiberglass with more elasticity than carbon. Basalt enhances board feel, power and stability while absorbing impacts and vibrations.

Aramid – Also known as Kevlar®, acts as a vibration dampener that softens rough landings. Durable, strong and extremely lightweight, Kevlar® is often used in ballistic body armor.

Sidewalls

ABS Sidewalls – ABS provides enhanced durability while keeping the core safe from moisture.

Base

Sintered 4400

Edges

5S Serrated Edges – Rossignol's exclusive edge technology offers five, smaller points of edge contact (one between the inserts and two on either side of the inserts), improving bite and grip along the entire edge for better stability.
