One-tool maintenance for field fixes. (M4 hex key)
Active snow and ice clearing.
And yes - it’s the best looking hardboot binding ever made.
Features
stack height
An ultra-low platform (12mm) keeps you closer to the deck for precision board feel and lightning-fast edge-to-edge response.
More stability. More confidence. More control - especially on hardpack and variable snow.
Active fixation
Our active fixation system pulls the splitskis together and locks the binding down for a fused, bombproof interface.
Zero slop. Zero play. Just razor-sharp initiation every single turn.
Plus - a glove-friendly latch for a fast, secure lock in any condition.
Damping and canting
Our hybrid canting blocks pair an ultralight aluminum frame for instant power transfer with TPU rubber that crushes chatter and kills unwanted vibration.
3° of knee-friendly canting = smoother riding, less leg burn, and more control when the snow turns chaotic.
TPU rubber also provides additional lateral flex for hardbooters.
Puck system
Every Ace binding comes with our proprietary QSW Puck System:
One turn screws the binding downwards - fusing the binding with the board
As the binding turns, the splitskis are mechanically cammed together
Automatic snow-clearing channels
Tech Toe Compatibility
For maximum stance width flexibility, a low-profile tech toe piece is recommended when pairing The Ace with an uphill touring setup. Low-profile options such as Grizzly Ski or Spark R&D / ATK tech toes provide the greatest clearance. If using a larger tech toe piece (e.g., Dynafit-style), QSW Tech Toe Adapter Plates are recommended to preserve adjustment range and optimal stance positioning.
