Section 2: Equipment
2.1 The Sled
The luge sled consists of two runner assemblies (called "steels") connected by two bridges (cross-members) known as "kufens." The sled has no mechanical steering, braking, or aerodynamic fairings. Key specifications:
- Singles (men): Maximum sled weight 23 kg (50.7 lb). Maximum length 150 cm (59 in). Maximum width 55 cm (21.7 in).
- Singles (women): Maximum sled weight 21 kg (46.3 lb). Same dimensional limits as men's.
- Doubles: Maximum sled weight 27 kg (59.5 lb). Maximum length 167 cm (65.7 in). Maximum width 60 cm (23.6 in).
The combined weight of athlete(s) plus sled is also regulated. Lighter athletes may add ballast weight (lead plates secured to the sled or worn in a weight vest) up to a specified limit. This ensures heavier athletes do not gain an unfair gravitational advantage.
2.2 Runners (Steels)
- Material: tempered steel with a specific hardness range regulated by the FIL
- Runner temperature: must not exceed the ice surface temperature by more than 5°C (9°F) at pre-race inspection. Artificial heating is prohibited.
- Runner profile: standardised gauge dimensions. Athletes may polish and prepare the running surface within FIL tolerances but may not alter the profile geometry beyond permitted limits.
- Runner curvature: slight bow is permitted within FIL template specifications, allowing athletes to customise their sled's response characteristics.
2.3 Athlete Equipment
- Helmet: Aerodynamic visor helmet mandatory, conforming to FIL specifications. Full face shield required. Helmets must pass impact testing standards.
- Racing suit: Skin-tight aerodynamic suit with maximum material thickness regulated to prevent concealed weight or aerodynamic modifications. Suits must be FIL-homologated.
- Spiked gloves: Used during the paddle start to propel the sled. Maximum spike length 4 mm (0.16 in). Spike material and pattern regulated.
- Booties: Aerodynamic foot covers (booties) are worn over the racing shoes to reduce drag. Must conform to FIL specifications.
