K2 Mindbender 89 TI W (2025)


VIP: $1,169.90


Excelling in on-piste performance and versatile enough to tackle softer snow, tame the mountain with the K2 Mindbender 89 TI W. Using the same construction as its bigger siblings, the Titanal Y-Beam construction means the skis stay damp and stable on more variable snow while an all-terrain rocker profile keeps turn initiation hassle-free. Full ABS sidewalls ensures precise edge-to-edge transitions on hard-pack and a waist width of 89mm allows you to venture from the prepared trails confidently. Keeping with the sustainability trend these skis use K2’s signature Bio-Resin to help reduce the carbon footprint in ski production. Approachable enough for beginner and intermediate skiers to get a taste of a hard driver and sendy enough for advanced skiers to really dig in, the Mindbender 89 TI W is a wonder to behold.

Y-Beam Titanal Construction
Titanal is placed directly over the edges in the forebody of the ski for predictable turn initiation. Underfoot the titanal spans the full width of the ski for maximum control and power transfer. In the tail we move mass away from the mount points increasing directional stability, resulting in consistent turn release

Aspen Micro Block Core
Lightweight and resilient, this makes for a great all rounder for core material. Many small stringers of Aspen give a consistent flex, smooth feel, and damp ride.

Bio Resin
Resin is the single largest contributor to a skis carbon footprint approx. 25%. K2 have managed to reduce the footprint by 30% with their new Bio Resin while also retaining strong bonding properties that can withstand the colder temperatures.

All-Terrain Rocker
Skis with All-Terrain rocker have a gradual rise to the tip for great versatility in all conditions, with a short, low rise in the tail for added control in variable snow

Full ABS Sidewalls
Power transfer is dramatically enhanced with the oversized ABS sidewalls that are laminated and pocketed within the wood core in the midbody of the ski. With the sidewall extending into the heart of the ski, the transmission of energy from skier to ski edge is direct and precise

Useful guidelines to assist you when buying your gear.

Ski buying guide

Skis come in many different types, shapes and sizes and are designed for a wide range of abilities and terrain. Maximise your enjoyment on snow by using the guide to help you select the perfect ski.

Beginner – Intermediate

This level covers new skiers that are getting to grips with the basics through to those who are cruising around the slopes linking turns top to bottom.  Skiing predominantly on the groomed/prepared trails.  This gear is more forgiving and encourages good progression to the next level.

Intermediate – Advanced

A majority of skiers fit into this level. These skiers can carve a good turn on the groomers as well as ski steeper freeride terrain or powder. This ability can ski with good speed and finesse in most snow types. The gear suited for this level can be pushed but is unlikely to be punishing if technique is off or a more chilled approach is taken.

Advanced – Expert

 Experienced skiers that have an aggressive ski style and demonstrate a higher level of technique whether on groomed runs or the steepest chutes on the mountain.  These skiers demand stronger equipment that is performance focused, usually stiffer and requires more input to get the most out of it.

Skis fall under different categories. The snow type or terrain you spend most of your time skiing on determines which ski would suit you the best. We have defined each ski category below to help you understand what ski you should be looking for.

Carving Skis
Also referred to as piste skis, groomer skis or frontside skis.  Carving skis are built to arch turns on prepared trails. They are typically narrower, around 70-80mm underfoot and have a nimble and quick edge-to-edge feel. Carving skis are constructed to hold and edge on firm and icy snow. Everyone should own a carve ski, it’s a good skill to have, from beginners to experts.

All-Mountain Skis
All Mountain skis share a lot of characteristics to a carve ski but usually with a slight wider waist width. All-mountain skis are better suited to someone that likes the feel of carving but heads off trail on occasions. The wider geometry under foot, helps in unprepared snow.

Freeride Skis
Freeride skis usually start around 90mm in the waist. The wider body helps with stability on ungroomed snow. Freeride skis tend to float better in powder and are easier to pivot (skid turn) thanks to longer and deeper rocker lines. A longer radius helps eliminate a catchy or grabby feel when in variable snow.

Freestyle Skis
These skis are developed for skiers looking for a playful feel. Freestyle skis are designed to perform tricks in the air or off features. The skis are designed with turned up tails (twin tips) that allow the skier to land backwards (switch/fakie). The tips and tails are often softer to help with absorbing landings, but also give good rebound or pop.

Backcountry/Touring Skis
Backcountry skis are designed with some degree of uphill in mind, and lighter weight being the top factor. Backcountry skis come in a broad spectrum of waist widths and even different weights.  Super light for uphill focus and medium weight for all round performance.

Powder Skis
Powder skis boast the fattest of waist widths, usually 110mm+. They have extremely deep and long rocker lines for maximum float in soft snow. They totally excel in deep untracked snow, perfect for Heli skiing, powder days or overseas skiing.

Race Skis
Race skis are the ultimate in performance, designed to be skied on the firm groomed trails at high speeds. The edge hold on a race ski is second to none, due to its solid construction. They require a very aggressive and technical skier to be able to control them.

The ski waist width (underfoot measurement) is one of the most crucial numbers when selecting skis. This measurement corresponds to the terrain/snowpack you will be most likely skiing on. A wider waisted ski is better for flotation in soft snow but can be harder to manage on firm conditions. A narrow waist ski offers quick edge-to-edge performance, but less stability in rough conditions.

These dimensions under foot are best for the skier that is dedicated to skiing on groomers and usually on firmer snow. The narrow waist offers quick edge-to-edge response and better power transfer that delivers higher levels of edge hold on ice. Best for aggressive on-trail skiers looking for high angle carving.

This waist range offers more stability to the ski. The extra width acts as a stable platform when the snow gets a little rough or cut-up on groomers. It shines on firm snow and is best for groomer skiers.

This is at the narrower end of the freeride skis. These skis offer the most versatility in the fact they can handle carving medium turns on-trail and are just as happy skiing off-trail in untracked snow, bumps, and steeps. When the snow is deep, a wider ski surfs much better.

Wider freeride skis offer more flotation in deep snow, plus the extra width provides maximum stability when charging through rough unprepared terrain at speed.

This width is designed for the skier that spends all their time freeriding in soft snow. They are harder to manage on firmer groomers and often have longer radii. This wide platform is the ultimate for flotation in deep powder and keeps the skier on the surface.

There are many different factors to consider when selecting the correct ski length. Height and weight are a good starting point but many other considerations need to be taken into account.  Like the typeof ski you are buying, the rocker profile of the ski, the snow conditions you aim to ski on, and your ability level.

Carving skis typically have a shorter turn radius and are designed to be skied in shorter lengths. All-mountain skis have a slightly wider waist width and are designed to be skied a little longer than carving skis for added stability in variable terrain. Freeride and backcountry skis are designed to be skied between eye and head height depending on rocker profile.

Reasons to go shorter:
• You are lighter than average for your height
• You prefer shorter turns
• You ski on-trail most of the time
• You are not an aggressive or fast skier

Reasons to go longer:
• You ski hard and fast
• You prefer longer turns
• Your weight is above average for your height
• You ski off-trail in variable conditions
• You are looking at a ski with a long rocker profile


Radius: The radius defines the turning shape of the ski. E.g. a short radius is around 11m, a medium 17m and long radius is around 21m. A short radius means the ski will turn quicker, fun on groomers. A longer radius is better in variable terrain as it won’t hook-up and grab making it more predictable.

Pivot: To turn/maneuver the ski in a skidding motion

Charger: Has a stable feel at high speeds, supportive with long effective edge. Tracks perfectly.

Playful: Fun and poppy. Good for freestyle and softer snow.

Damp: Composed at speed on firm snow, quiet in terms of micro movements. E.g. a metal laminate ski is damp, a light-weight core ski is not damp.

Directional: Skiing in a forward direction with a carving inspired stance. Doesn’t ski switch or freestyle.

Variable Snow: A mix of hard and soft snow. Can be grabby and unpredictable to ski through.

Taper: The widest point of the ski tip and tail is brought closer to the centre. Taper reduces a catchy/hooky feel laying the ski over, but on flip side loses some of the carvability.

Sidewall: Sidewall construction is a traditional style of building skis, it’s the strongest, offering more power to the edges, torsional strength, and more robustness.

Titanal: Often referred to as “Ti” or metal. Titanal is a alloy mix used in some ski construction to make the skis more damp and stable. Hardly any skis on the market are made from Titanium.
