Reveal 01Shell Construction

From raw layup to race livery.

Each shell begins as 47 precisely cut plies of T700S carbon fiber, hand-laid in a [0/±45/90]s sequence optimized for torsional rigidity at 140 km/h lateral G-loads.

Shell mass: 2.1 kg · Torsional stiffness: 840 N·m/deg

Reveal 02Runner Grinding

Steel ground to the last micron.

CNC-roughed blanks enter a 14-pass hand-grinding sequence. Final edge radius: 4.0–6.0 mm per FIL specification. Surface finish Ra ≤ 0.05 μm — smoother than a surgical instrument.

Runner steel: 1.4034 · Hardness: 52–56 HRC · Tolerance: ±0.002 mm

Reveal 03Aerodynamic Validation

Wind tunnel to world cup.

Every shell profile is validated in our 40m/s closed-loop wind tunnel before it sees ice. Drag coefficient targets: Cd ≤ 0.18. The data informs the next layup iteration.

Engineering // Materials & Process

Every gram justified.
Every micron measured.

We don't build sleds in volume. We build them one athlete at a time, with the obsessive tolerance of a watchmaker working at 140 km/h.

Material System

T700S Carbon Fiber

Tensile strength 4,900 MPa. Modulus 230 GPa. Each ply orientation calculated for the specific load path of a luge descent — not borrowed from automotive or aerospace, purpose-derived for ice.

Tensile: 4,900 MPa · Modulus: 230 GPa · Density: 1.78 g/cm³

FIL Compliance

Olympic-Class Certification

Every sled exits the workshop with a FIL homologation packet. Mass, runner geometry, and safety compliance documented for federation submission.

Runner Steel

1.4034 Martensitic

Vacuum-arc remelted. Hardened to 52–56 HRC. Profile ground to ±0.002 mm across the full 1,340 mm contact length.

Fitting Protocol

Athlete-Specific Geometry

Body mass, height, hip width, and preferred weight distribution are fed into our parametric shell model. No two sleds leave the workshop identical.

Lead Time

8–12 Weeks

From fitting appointment to race-ready delivery. Rush production available for qualification campaigns — contact the workshop for availability.

We switched our entire Olympic squad to Sled equipment after Innsbruck 2024. The runner consistency across six pairs was within 0.003 mm — tighter than anything we'd sourced from the established suppliers.

I'm self-funded. Every hundredth I can find in equipment pays for itself in prize money and sponsorship leverage. The fitting process took half a day and the sled came back 0.08s faster than my old setup on the same track.

Our development program runs 14 junior sliders. The forgiving shell geometry Sled built for the program absorbs the impact loads when kids are still learning to hold their lines. We've had zero equipment-related DNFs this season.
