Rocker Type

AmpTek All-Mountain Rocker – AmpTek All-Mountain features softer tips and a stiffer waist with 40% camber between the feet for powerful edge grip and stability, and 60% rocker at the tip and tail and forgiveness for effortless freeride versatility.

Flex

Flex Rating: 8 (1 Soft - 10 Stiff) – A stiff flex provides power and stability for high speed freeriding.

Twin All Mountain Flex - – A symmetrical flex which is stiff under feet for punch and grip, with a stiffer waist for stability at high speed. Maximum pop and balance for freestyle riding.

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.

Twin Freestyle – Symmetrical flex. Stiffer under feet for pop and balance. Softer waist for easy manipulation and control.

Core

Wood CK/S-Tips – This construction utilizes carbon and aramid (Kevlar) strips down the middle and directly underfoot, and stretching out to the edges to deliver explosive pop while also providing excellent shock absorption.

Laminates

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.

Glass Fiber – Delivers customized flex with increased torsional resistance and stability.

Carbon – Combining high-flexibility with high tensile strength, low weight, high resistance, and low thermal expansion make carbon fibers the perfect pick for explosive pop.

Sidewalls

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

Base

Sintered 7500

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.
