7005AA Speed Skating Blade
The 7005AA Blade is a high-performance speed skating blade engineered for all-distance skaters weighing 50–70 kg, optimized to deliver elite-level performance with the structural capacity to support extreme single-lap times as fast as 8.4 seconds.
Built with a 7000 series high-grade aviation aluminum tube, the blade offers an exceptional balance of lightweight responsiveness and structural strength. The tube features a hardness of 16.5 and a yield strength of 105–110, ensuring stability under high load and powerful stride transfer.
The blade incorporates a bi-metal edge design, combining durability and precision:
- Edge hardness: 61–62 HRC, providing superior ice grip and cutting efficiency
- Powder Metallurgy (PM) blade edge/base hardness: 50–52 HRC, enhancing toughness and wear resistance
With a 1.1 mm blade thickness, the 7005AA delivers precise edge control and reduced drag, ideal for competitive racing. The geometry is carefully tuned with a 9 m rocker radius for optimal glide and maneuverability, and a 23 m lateral bend radius to support smooth cornering and stability at high speeds.
Overall, the 7005AA Blade is designed for skaters seeking high-speed efficiency, control, and durability across all race distances, making it a reliable choice for both competitive and performance-focused athletes.
