About Kessler Technology

Kessler Shape Technology

K essler Shape Technology KST stands for a sophisticated interaction between side cut and baseline.

a) Ski under load stress: The red line corresponds to the contact surface in the snow. This is shorter than with the traditional ski. The ski is therefore very easy to turn. At the same time the small aggressive radii at the point of the ski and at the end are eliminated, which means that the ski can not catch on these points. KST = SIMPLE

b) Ski under load stress, tipped over: When tipped, the contact surface becomes larger, the contact points move towards the front and the back, and this leads to very high curve control and grip. At the same time ever smaller radii are exerted. Irrespective of how the ski is tipped, tight turns as well as wide swings can be carved out at any speed in a controlled manner.

KST = HIGHEST PERFORMANCE KST – that means rocker comfort on piste and icy terrain. A technology quantum leap resembling that of the carving revolution. The Kessler Shape Technology, developed and patented by Hansjürg Kessler, enables us to combine the enjoyable effects of rocker-boards and -skis on the ski piste with the demands of safety, grip of edges and stability. The special clothoid board geometry allows applying an infinite number of radii on turns and permits variable turn radii with one and the same pair of skis: carving small and tight turns as well as long drawn-out turns at all speed levels. The pressure of the edges is effective where it is needed and at the same time reduced where it handicaps. There is no longer the danger to easily catch edges, and the strain reduction on the body is a huge gain of safety at all performance levels.

In the words of one tester:

This ski could carve perfect turns on concrete. But the surprising part is that the ski is easy to handle at slow speeds. I'm guessing this has to do with the mildly upturned tip and tail or some magic Swiss ingredient. Absolutely superb on-piste weapon.

The specially designed geometry of Kessler skis effectively applies pressure to the edge where it’s needed and reduces it where it’s not. KST is attracting a great deal of attention and interest from top ranking skiers on the ski circuit, and has also recently been used to develop a range of skis for the recreational skier. The results have been outstanding! The danger of catching an edge has been removed, and the many radii that are contained within the geometry of the ski results in maximum performance for both wide curves and the tightest of turns. KST reduces the strain on the body meaning less risk of fatigue in the skier. This is a considerable improvement in safety for both top professional skiers and beginners alike.

A Rider's Tale

o what does KST mean to the recreational skier and snowboarder? When I first saw the Kessler Phantom ski, I was a bit intimidated. I've been skiing for over 25 years but I have never been a racer. In fact, I'm positively allergic to Spandex. I could see that the ski was all about effective edge, with a truncated nose and tail. Since I like to ski fast, that looked like trouble.

Swiss ski meets Eastern crud

To make matters worse, the evening before my first test day, it rained. Then froze. Then the groomers dutifully cut up the ice into tennis ball sized chunks. "Beaver balls" or "death cookies" depending on where you're from.

So what happened when I got out on traditional Eastern "chunky powder"? Nothing short of amazing. The first thing I noticed was the quiet, stable ride. Instead of chattering along with tips flapping through the ice, the Kesslers sliced through like they were on a mission.

I liked the way the early rise tip basically rode over the crud while the cambered centre gave me confidence at high speed and enough pop to transition freely from carve to carve.

I was sold on Kessler technology for the quiet, damp ride and enormous edge grip. Now I am thrilled to be part of bringing this great product to Canada.
