Arbor Westmark Rocker 2021 *PREORDER*

Size Chart
- +


The 2021 Arbor Westmark is the park board of choice for many Arbor riders, and with a Transworld Good Wood award under its belt, it's not hard to see why. Hitting that sweet spot between soft and stiff, the Westmark maintains easy pressability for park or street rails without sacrificing the stability and speed to hit bigger jumps or charge around the mountain. The true twin shape makes it super easy to ride switch, and the Flathead tip and tail shape are there to be grabbed, blocked, and turn heads. The Westmark comes in both camber and rocker profiles, so whether you prefer the easier, more buttery ride of rocker or the more stable, poppy ride of camber, you're covered either way.


This board is scheduled for delivery to Melbourne Snowboard Centre in June 2020. This is an estimated delivery window and is subject to change. You will be notified via email once your board is ready to be collected in store, or once it has been shipped (if being shipped).

Key Features

Board Type: Park, Street, All Mountain Freestyle

Camber Type: The Rocker System

The Rocker System from Arbor is a parabolic take on reverse camber that progressively reduces the amount of rocker towards the tip and tail. This results in your contact points being closer to the snow, allowing them to engage quicker and more effectively for enhanced response and stronger edge control, while still maintaining the natural float and surfy ride of rocker

Flex: 5/10 (1 = soft, 10 = stiff)

A mid flex that is versatile enough to ride the whole mountain.

Shape: True Twin

This board is constructed exactly the same tip to tail, so will ride exactly the same in regular or switch.

Flathead Tips - A unique freestyle-oriented tip shape that provides more surface area for ollies and presses.

Grip Tech

Grip Tech is a combination of three separate sidecut radii in the nose, tail, and centre of the board, effectively giving the board an additional two contact points. This provides extra grip and control in all conditions, and also makes turning smoother, easier, and less catchy, without losing performance.

Core: FSC Certified Highland Core

The most versatile in the Arbor range, with a 1:2 poplar to paulownia blend for a lightweight, durable performance core.

Biax Glassing - A full Biax layup that's designed to be softer flexing and more forgiving for freestyle inspired all-mountain riding.

Base: Sintered Base

A high molecular weight base that provides extra durability and speed.

Mounting Pattern: 2x4 14-Pack Inserts

Additional Features:

Hand Dyed Ash Power Ply Topsheet - This creates the style Arbor is known for, but isn't just for looks. Power Ply is a sustainably sourced layer of wood or bamboo that acts like an added layer of fibreglass due to a labor intensive process that results in increased performance, finish quality, board life, and less reliance on man made materials.

Bio Plastic Topsheet - Made from Castor Bean Oil, this top sheet is extremely durable, water repellent and helps to minimise petroleum based plastics from the production of the board.

360° Fully Wrapped Sidewalls - These 360° sidewalls eliminate the need for tip fill, enhancing durability and improving board life.

Recycled Steel Edges - These highly durable recycled steel edges promote sustainability without sacrificing quality.

Entropy Bio-Resin - This board is made with Entropy Bio-Resin, which is a replacement for traditional petroleum-based resin that doesn't affect performance. The ingredients that go into Entropy Bio-Resin are co-products or waste products of other industrial processes and reduces the carbon footprint of the material by up to 40% (when compared to a petroleum-based equivalent).

Wend Natural Wax - This board is waxed with Wend Natural Wax and is ready to ride straight out of the shop.

Factory Tuned - This snowboard is factory de-tuned at the tip and tail, so you can go riding straight away.
