Skis Ogasaka Triun SL 2018th year were cardinally redeveloped in comparison with the previous model year. The skis had a more radical side cutout, they became stiffer, the shape of the deflection also changed. First of all, I was concerned about the rigidity, since the skis of the previous model year were already quite tough, much stiffer than the skis of the “race stock” from other manufacturers. Therefore, even more greater rigidity of the skis of 2018 caused concern about whether it would be possible to bend skis on the Moscow hills, where the speed is less than in mountains. The answer could only be by snow. Snow is not good yet. There was no good hard cover in December 2017, and there was no opportuntity for testing in the slalom course. Nevertheless, the first impressions already exist. Continue reading Ski Ogasaka Triun SL 17/18. Part 4, test on snow
In this note I will consider the stiffness of the slalom skis Ogasaka Triun SL 17/18. In addition, from the analysis of the shape of the deflection I will try to evaluate the “rails” in the arc of a carved turn. Continue reading Ski Ogasaka Triun SL 17/18. Part 3, stiffness and deflection
The catalog indicates that the radius of the side cutout of the Ogasaka Triun SL 17/18 ski, length 165 cm, is 11.0 meters. This is a fairly radical cutout for nowadays slalom skis, the traditional radius is 12.5 + – 0.3 meters. It is also interesting how much the shape of the side cutout corresponds to a circle, that is, how much possible to speak about the radius, and not just the “radicality” of the side cutout. For this purpose I measured the width of the ski in 0.5 cm steps.

Information about the Ogasaka ski collection of the next 2018 year began to arrive in March 2017. Ogasaka arranged testing in many ski centers in Japan. There were first reviews in the Japanese and Korean Internet. True, which is rather strange for the Internet era, the information was given in small portions and very carefully. Photos of a large size were sometimes removed after a day, and sometimes the images of skis were blurred over. Previously, I have not seen this 🙂 Just in case I asked Iwamoto san whether it’s worthwhile to spread the detailed information about new skis. Iwamoto san specially asked at the factory, they gave OK 🙂

Of course the radius of a carved turn is determined not by the skis, but by the skier 🙂 Nevertheless, the skis may have its own “favorite arc”, along which it goes like along rails. Curvature of the arc varies with the angle of the edge. What is especially nice, a skier for carving a “favorite arc” does not need at all (you can replace it with a сast-iron weight). And if the desire of a skier to go along the arc coincides with the ability of the skis to cut just such an arc, then probably the perfect carving will turn out. In this note, I will examine how the radius of the sidecut of the skis and radius of a carved turn are related. Based on the skis Atomic Redster FIS SL 165 cm (2016) .

For the last 15 years, ski sidecut radius is usually written directly on the skis next to the precise parameters of the geometry of the ski: the length and width of the tip/waist/tail. The shape of the side cutout is different for different manufacturers and in general is probably connected with the “secrets” of the firm 🙂 Then what does the “radius” mean? I immediately have an association with a circle, that is, with a curve that is completely determined by one parameter “radius”. In this note I will try to understand how much the shape of the side cutout corresponds to the circumference.

The time of descent on the slopes of the Moscow hills is about 20 seconds. The slope ends much earlier than legs get tired. In the slalom course there are usually no more than 20 gates. This is much less than the “real” slalom in the mountains, when you often come up to the last gates on “iron” legs. How important is the physical condition for slalom in Moscow? How much do you need a “real” sports approach with special physical training in the summer and with additional training in the hall in the winter? And in general, how much depend the level of skiing from physical fitness?

In this note I want to give some tips for & tricks for skiing in slalom course. Behind general considerations, theory, exercises there are also specific advices that can help immediately. I’ll give three slalom skiing tips & tricks that really helped for me in this season (2017).

Slalom trainings are usually conducted with the coach. In this case, as the coach will say, so the training will be built. I want to share my views on the opposite approach. A team with own training equipments rent a slope and skiing along a course. Probably every such team has its own traditions. Our approach varies slightly from year to year. I’ll write how the trainings were arranged in the season of 2017.

Skiing is certainly assumed for skiing in the mountains. It is not so important, on the course or without a course. Skiing from small hills (for example, in Moscow) is mainly aimed to learning or training. But after you’ve learned to ski so that you can ride in the mountains, regular free skiing in Moscow generally loses this reason. The slalom course can motivate. When I had the opportunity to become an amateur sportsman and regularly ski on slalom course, the free-skiing trainings in Moscow ended (except of skiing with the family, of course). But in the past three seasons, it was possible to allocate time for free-skiing trainings in addition to training on the course. Therefore, I want to formulate what is better to train separately in free skiing and then transfer to the course.
