Olympic bobsledding usually will get referred to as the “System 1 of ice.” Tracks are greater than 1.5 kilometers (almost a mile) lengthy, and athletes usually race down them at speeds nearing 145 kilometers per hour (90 mph). Bobsledders—whether or not in groups of 4, two, or sliding solo—are sometimes subjected to gravitational forces in extra of 5g. On the 2026 Milano Cortina Winter Video games, they’re utilizing tech geared toward making every section of the race, from preliminary push to technical driving to remaining braking, just a bit bit extra exact than in earlier Video games.
Males’s four-person bobsledding made its Olympic debut in Chamonix, France, in 1924; ladies’s two-person bobsledding didn’t enter the Video games till 2002 in Salt Lake Metropolis. Girls’s monobob arrived in 2022. Whereas the earliest bobsleds have been fabricated from wooden, the game has been synonymous with metal for years, though in current many years it has been changed by carbon fiber, which gives larger lightness and power.
Every new technological growth within the sport has come amid the constraints essential to preserve athletes protected, reminiscent of weight and sled sizes. The 2-person bobsled can have a max size of two.7 meters (about 8.9 ft) and a max weight of 390 kilograms (859.8 kilos), together with crew. A four-person bobsled can not exceed 630 kilograms (1,388.9 kilos), together with bobbers, and three.8 meters (12.47 ft) in size.
The load restrict was a needed transfer to equalize race situations and curb using athletic specialists who, though not bobsledders, have prior to now confirmed decisive of their groups’ success by the pushing section. That is removed from coincidental, as a result of this is among the areas the place know-how makes the most important influence bobsledding.
On the 2022 Beijing Olympic Video games, Germany gained 27 medals, 16 of which got here from bobsledding, luge, and skeleton. German athletes are likely to excel at bobsled as a result of the game has a protracted custom in Germany but in addition as a result of the nation has lengthy targeted on innovation within the sport. Automaker BMW, for instance, is a strategic companion of the the German federation that oversees bobsledding, luge, and skeleton (Bob- und Schlittenverband für Deutschland) and is credited with the introduction of customized studded footwear, a vital instrument for bobbers’ efficiency.
The primary 30 to 50 meters of Olympic bobsled usually show decisive in a race, as a result of it’s the solely time when athletes can push the sled to succeed in max acceleration. A few years in the past, BMW realized that improvements within the bobbers’ footwear might enhance their efficiency throughout that essential time.
Wanting on the preferences for every crew member, BMW made customized spike plates that may be built-in into any sort of shoe. Utilizing 3D printing, the corporate was in a position to adapt the stiffness and form of the studs for various footwear and wishes. Working this fashion allowed them to experiment and modify designs rapidly. To keep away from extreme put on or breakage, the spikes are given larger hardness by plasma nitriding, wherein nitrogen is ionized in a high-temperature vacuum and subtle into the metal.
