The Hydra is our most popular model — a high-performance monoski with unique suspension kinematics that performs exceptionally well for racers and intermediate to advanced recreational skiers. The Hydra automatically moves the body of the monoskier as able-bodied skiers do in a turn: it applies pressure near the ski tip during turn initiation to begin bending the ski, then moves the skier backward on the ski to center the pressure at the apex of the turn, and finally shifts slightly to the back to straighten the ski and accelerate out of the turn. This movement helps users – especially those with limited upper body mobility – shift weight and turn more easily.
To our knowledge, the Hydra is the only monoski on the market with this kind of suspension system, and better pressure distribution also leads to better control. The Hydra retains the competitive advantages of all DynAccess monoskis: extremely responsive and strong, with an exceptionally stiff frame, made from high-grade materials yet relatively lightweight. This is achieved through a unique structural geometry, custom-developed high-quality bearings and hardware, and a Penske Racing shock absorber specifically designed for DynAccess. The Hydra sits stably on lift chairs — it sits further back on the seat and tilts the rider slightly backward. Standard finish: clear hard anodized; custom colors available upon request.
The Hydra Light is a lighter version of the Hydra monoski, specially developed for lighter skiers. It is a completely redesigned monoski, and almost every part is lighter than on the regular Hydra. The complete frame with shock, etc. (without a seat or a footrest) weighs 15.4 lbs. (7.0 kg) and 18.2 lbs. (8.2 kg) with a footrest. This is 6.5 lbs. (3 kg) lighter than the regular Hydra.
A new lightweight shock with a single spring was developed for the Hydra Light, based on a mountain bike shock but modified for DynAccess monoskis. It features a custom-made ice scraper, cold temperature oil, and modified damping by Penske Racing Shocks, with both high & low speed rebound and compression damping adjusters. If desired, a full-size Hydra shock can be installed in the Hydra Light frame. The Hydra Light works best for skiers under 135 lbs, and the frames are anodized in Red or Light Blue as standard.
The Tensor is a high-performance and highly versatile monoski. It accepts different types of shocks — including air shocks, coil-over shocks, and light-duty shocks — allowing you to customize your ride and ride height. Standard setup includes the Penske Racing Shocks Pro-Air: dual-chamber air spring (Chambers 1 & 2), hydraulic damping, and easy adjustability of spring rate, ride height, rebound, and compression damping (no tools needed). Weight (w/o seat): 23.25 lbs.
Benefits: high stiffness for excellent control, stable lift-chair positioning by sitting further back and tilting the rider slightly backward, and suitability for racing, recreation, and adaptive programs alike.
Our strongest model to date. The Torque 2 uses thin-walled, closed-section chromoly members for its frame, suspension link, and “boot” tower — making it extremely stiff and durable. This stiffness translates to superior rider control and a crisper feel on the slopes.
The Torque 1 is the original DynAccess monoski. It’s compact and lightweight, weighing:
23 lbs without a seat
20.5 lbs without a footrest
The Torque 1 features a steep thigh angle (40°), which reduces the moment of inertia and helps the skier initiate quick, responsive turns.
