2026 GNU Upgrade C2X Snowboard
The 2026 GNU Upgrade C2X is Jeff Henderson's high-performance all-mountain freestyle board, designed to balance playful versatility with the stability and response needed to charge the entire resort. Its Hybrid C2X profile combines a shorter, more aggressive rocker zone between the feet with powerful camber underfoot for pop, precision, edge control, and dependable stability. The Directional Twin shape keeps it versatile for freestyle riding while Directional Triple Serration Magne-Traction® concentrates edge hold where it matters and keeps the tip and tail smoother for presses, butters, and clean takeoffs. A lightweight G Lite 2 Aspen and Paulownia core, Carbon Power Bands, and fast Eco Sublimated Sintered Base round out a versatile board built for everything from park laps and side hits to carving and technical resort terrain.
