DYNO DH
Hardboot Splitboard Binding
The Dyno DH is our acclaimed hardboot specific splitboard binding. It is designed to fit a variety of touring boots from different brands and delivers high-end performance to the dedicated hardboot segment of splitboarders. All parts are designed and manufactured by us from start to finish for the all around precision that you can only get from a Spark made product.
Dyno DH bindings are for riding only. Carry them in your pack on the way up, while using your tech toes for touring. Then slide the Dynos on your pucks and lock into place with the snap ramps for the ride down. Fits boots with 255 - 340mm sole length.
FEATURES
- Extremely Lightweight - only 409 grams per binding
- Stainless steel toe and heel bails
- Toe clip is designed to fit even low profile AT boots
- Efficient design saves weight while maintaining backcountry dependability
- Set screw has a 4mm hex drive, found in our Spark Tool
- Baseplate heel end is reinforced and extra sturdy to avoid
bending from heavy use - Features Tesla Snap Ramps for speedy, pinless transitions
- Puck compatible (Spark Canted Pucks recommended)
Weight: 0.90 lb/ea (409g) – 1.80 lb/pr (818g)
NEW SPARK x ATK TECH TOES
A Spark R&D and ATK Binding collaboration designed and based off of the ATK Toe Piece from the Trofeo series - "Performing on Lightness."
Built specifically for the split-hardbooter, the new Spark x ATK Tech Toes utilize ATK’s signature monolink technology with smoother entry, better retention and 20% weight savings compared to the original Spark Tech Toe (now discontinued). With an integrated hole pattern for factory splitboards there is no need for an adapter. Pair with our Hardboot Dual Height Wires, and compatible D Rex ST Pro Crampons to be ready for the skin track.
FEATURES
- ATK Monolink Technology: Ergal 7075 aluminum sidearms and monolink technology. A smart layout that utilizes one pair of springs to lock your boot firmly in place.
- Integrated Crampon Mounts: Built-in claw mounts allow for easy use of the D Rex ST Pro Crampons and original D Rex Crampons (now discontinued)
- Adjustability: Slotted rear holes compensate for splitboard insert pattern compatibility and variability.
- Riveted Pins: Pins are riveted to the toe piece arms, making the loss of a pin in the backcountry nearly impossible. Heat treated for incredible wear resistance.
- Center Screw: Robust stainless steel center screw for easy no tool installation.
- Lock Lever: Slimmed down aluminum lock lever saves weight and handles more abuse than plastic designs.
The original Spark Tech Toe was discontinued in the summer of 2025.
Weight: 4.23 oz/ea (120g) - 8.46 oz/pair (240g)
