Spark R&D D-Rex Splitboard Crampons

No. The D-Rex is designed for on-the-fly installation, so you can attach or remove them while your boots are still in your bindings. This is a major advantage when you encounter a sudden patch of ice mid-climb.

These are specifically designed for use with Spark R&D Tech Toes and Dynafit Speed Radical toes. They are not universal, so confirm your toe piece compatibility before purchasing.

They are engineered with a riser-mounted system that keeps the teeth at a consistent depth in the snow, even when your heel lifts are engaged. This ensures you maintain reliable traction on steeper ascents.

The pair weighs 373 grams. While it adds a bit of weight to your setup, the security and efficiency they provide on technical or icy terrain usually outweigh the minor penalty.

The main benefit is the direct attachment to the tech toe, which allows for a much faster transition. Because they aren't mounted to the binding itself, they offer a more stable, consistent engagement with the snow surface.
