Inline downhill
Inline downhill is a form of inline skating in which an asphalt (mountain) route is driven down. A typical downhill track has an average gradient of 7 to 13% and has several hairpin turns . The average speed is around 60 km / h. However, on certain stretches a speed of around 110 km / h is reached. The FIRS world championships have been held annually since 2000 . Races have been held regularly in the European Cup since around 1995 . The European Cup was replaced by the World Cup in 2001 .
material
Racing suits from alpine skiing are used to improve aerodynamics . Some drivers use leather suits from the motorcycle sport .
The inline skate is usually a combination of a slalom shoe (high shaft with good grip) and a rail with five rollers . Since only a few manufacturers offer special downhill shoes, the material is usually combined from several manufacturers.
Since the brake pad or brake rubber does not achieve the desired deceleration, many drivers have removed the brake pad and brakes with the wheels (sliding).
In order to achieve a good combination of speed , cornering stability and slide ability, most riders use bikes with 84 or 100 mm diameter. Depending on the distance and body weight of the driver, a hardness of 80-84A is used for the rollers.
safety
The curves on the race tracks are secured with air mats, straw bales and mattresses. Exposed areas such as lamp posts or large stones are additionally secured. The downhill courses are checked for safety and complete security by the members of the IIDA committee before the race.
Race may consisting only with a full equipment face helmet , back protector, knee and elbow protectors are driven (chin protection).
Braking techniques
Should best be learned in the order described.
Brake block The brake block is mainly used for reasons of cost, as sliding with the wheels causes considerable wear . However, depending on the shoe system, the brake block harbors certain risks at high speeds , since the entire weight then only rests on one roller. This can result in uncontrolled slipping of the shoe. However, some good drivers swear by the brake block.
The T-Brake With the T-Brake, one foot is placed 90 degrees to the side and pulled behind the body. Since not all of the weight can be placed on the braking foot, the T-Brake is rather inefficient when downhill and is therefore mockingly referred to as raclette by some drivers. However, the T-Brake has the advantage that at least one shoe still has fresh wheels and enough grip while driving and the posture is relatively stable.
The snow plow With a snow plow , the legs are spread apart and the tips of the feet are turned towards the center of the body. The snow plow is mostly practiced by new drivers as a preliminary stage to Magic or Powerslide. Triggering the snow plow takes some courage, especially at high speeds. However, you have a stable position and can quickly continue in the direction of travel in the event of a fault.
The Magic The Magic is a continuation of the snow plow and serves as a preliminary stage for the Powerslide. In addition to the spread legs, the entire body moves 90 degrees to the direction of travel. Both shoes slide across the direction of travel. The Magic is the most aesthetic way to brake. However, since you only brake with one foot in the direction of travel, the rollers wear out unevenly and you lose a little efficiency.
The Powerslide is the supreme discipline in inline downhill. As with the Magic, the body is rotated 90 degrees to the direction of travel. However, both feet are in front of the body in the direction of travel. Triggering the Powerslide requires calm, skill and some training . It is the most efficient way to brake and causes the least amount of wear on the rollers and the brake pad. At a speed of 80 km / h, however, it still takes around 30 meters to come to a standstill.
Associations
The inline downhill umbrella organization is the IIDA (International Inline Downhill Association) , which organizes the World Cup in inline downhill. The IIDA was founded in 2001 during the World Championships in Lausanne and expanded the European Cup held at that time with international races. The IIDA consists of a president (Davide Tacchini ITA) and a committee (each a country representative, who is the contact person for the drivers).
In America , the IGSA (International Gravity Sport Association) organizes races. However, the IGSA is not a pure inline downhill association, but also organizes races for longboard and street luge .
IIDA and IGSA work closely together. For this reason, some races are counted by both organizations .
The FIRS (Fédération Internationale de Roller Sports) is responsible for the implementation of the world championships.
In Germany , Austria and France , the drivers are integrated into the national roller sports organizations.
