DETAILED DESCRIPTION
Extreme Glide, Uncompromising Efficiency
The Razor series is designed for riders seeking a pure, fluid, and continuous foiling experience. This high-aspect front wing is built for exceptional glide, incredible pumping power, and outstanding performance in downwind and prone surf conditions.
Power, Flow, and Precision in One Shape
Every detail of the Razor's design is optimized to convert rider input into speed and directional control. The result is a highly efficient front wing that maintains clean, stable water flow even through the most technical transitions. It provides endless glide from its high-aspect profile, impressive pumping for its size, and consistent speed and control over long runs, with a smooth, fluid response through carves and glides. The WR977/BB combines with a Blackbird stabilizer and a Sabfoil mast for the complete high-performance setup, or with Blackbird Backtail fuselages to use Kraken stabilizers for maximum modularity.
Blackbird Technology: Designed to Perform
Hydrodynamic efficiency and reduced drag: The streamlined shape and monobloc construction slice through the water, improving flow and reducing turbulence. Active Lift and trim optimization: The wing generates extra lift for earlier take-offs and reduces pressure on the rear stabilizer. This results in a flatter, faster, and more balanced ride, even at high speeds. Extreme structural stiffness: The aerospace-inspired fuselage design increases torsional stiffness by over 20% compared to standard cylindrical fuselages.
Who is it for?
The Razor 977 is for ambitious, technical riders, freestylers looking for pop and control, downwind and wave riders who want speed and flow, and anyone who wants a front wing that feels like a natural extension of their body. Its MONOBLOC Full Carbon construction ensures minimal flex and torsion, delivering smoother transitions, instant feedback, and a truly connected ride feel.

FAQ, SABFOIL RAZOR BLACKBIRD 977
Sabfoil designed the WR977/BB for ambitious and technical riders, freestylers looking for pop and control, and downwind and wave riders seeking speed and flow. It offers a take-off speed of 10-12 knots and a top speed of 22-24 knots for an 80 kg rider.
While all four front wings share the same Razor philosophy (high-aspect, MONOBLOC Full Carbon), they target different uses. The 977 (953 cm², AR 10.2) is the most versatile, covering five disciplines: Wing, Surf, Downwind, Pump, and SUP. The 737 (648 cm², AR 8.4) is specifically for prone surf, reaching 25-27 knots at its peak. The 847 (784 cm², AR 9.2) targets downwind and prone surf. The 1077/BB is the largest in the range.
Sabfoil recommends the FBB/S, FBB/M, and FBB/L fuselages (Blackbird Backtail Alu sizes S, M, and L). Please note that the fuselage is not included with the front wing.
Yes, the front wing includes the Sabfoil MH172 "Mast to Blackbird" screw set, making it compatible with masts from the Sabfoil range.
Sabfoil recommends pairing the Razor Blackbird 977 with the SDW375/BB stabilizer (Stabilizzatore Downwind 375 Blackbird).
The Sabfoil Front Wing D bag (product code MA028) is designed to be a perfect fit for the WR977/BB, as well as the WR847/BB and WR1077/BB models.
