The ATK Raider 12 SL is exactly the same as the Raider 12 AP except that it does not have the Up-Hill Hardness Variator option in the toepiece. The toepiece is 15 grams lighter and the Raider 12 SL weighs in at 330g / ski or 660 g per pair. Rather confusingly the Raider 12 SL has ATK's automatic AP ski brake system just like the Raider 12 AP. These brakes are very easy to use. Simple press down on the brake plate and rotate the heel unit to block the ski brake. Activated in one simple movement, the AP Brake System guarantees safe and reliable transitions between walk and ski modes, improving the functionality of the bindings.
The toepieces of the Raider 12 SL have ATK's Easy Entry System to facilitate boot entry into the toe piece. The front lever is longer and more ergonomic so easier to use, especially in difficult situations when fatigue complicates even the simplest operations. The plastic protector reduces the wear and tear of the toe lever. Step-in is intuitive and fast whatever boots you are using. The toe piece of the R12 SL has a special design to avoid snow and ice build up under the spring mechanism. Called Snow Pack Proof, this design prevents snow accumulation even after several uphill/downhill transitions.
The Raider 12 SL has a fully adjustable heel unit. Lateral and vertical release can be adjusted independently with a range 5-12 DIN. The heel unit has ATK's excellent Cam Release System. This stabilizes the heel pins and provides the torsional stiffness ATK bindings are reknowned for. The special cam profile is pressed against the heel pins by a pre-tensioned spring: during step in, or on the event of a fall the pins are forced to go through the cam profile which provides a precise resistance to pin release depending upon the release value set on the bindings. This mechanism provides the most stable downhill performance on the market with consistent reduction of boot torsion compared to any other tech heel unit design. It also provides the softest heel step in of any bindings.
Most modern free rando insert bindings now include a system to compensate for ski flex and the R12 SL has ATK's Elastic Response System. The heel unit is mounted on a baseplate that can slide forwards and backwards to absorb ski flex. Unlike some other brands who no longer recommend a gap between the heel unit and boot (since the heel unit will move with ski flex), ATK still recommend adjusting the heel unit to have the 4 mm space. However the principle is the same, allowing the ski to flex without the binding and boot blocking the centre of the ski, reducing pressure on the bindings during ski compression and giving more reliable release performance.
The Raider 12 SL also features ATK's Magneto Heel Flaps: A simple yet ingenious magnet system provides stability to the heel unit and ease of use. Lightweight and convenient in use.
ATK's success is based upon precision manufacturing and designs using as much metal and as little plastic as possible. ATK bindings are light, compact and torsionally rigid. These characteristics are particularly important for free rando bindings where the greater stresses involved with wider and heavier skis soon show any weaknesses in binding design.
Weighing only 330 g per ski, the ATK R12 SL is designed to supply a high level of control and feedback while remaining light for long tours in the backcountry.

AP Brake System: ATK's AP brake system really couldn't be easier to use. Simple press down on the brake plate and rotate the heel unit to block the ski brake. Activated in one simple movement, the AP Brake System guarantees safe and reliable transitions EES Easy Entry System Toepiece design gives easy and confident step in action with all tech boots, even when boot soles are worn. Snowpack Proof The design of the toe piece prevents the formation of snow or ice accumulation under the toe mechanism, ensuring relieable release and annoying balling up even after numerous uphill / downhill transitions Magneto Heel Flaps A simple yet ingenious magnet system provides stability to the heel unit and ease of use. Lightweight and comfortable to use. Cam Release System Cam Release System:This mechanism inside the ATK heel units to facilitate both boot entry and binding vertical release in the event of a fall. Elastic Response System The heel unit moves on a rail to absorb ski flex and provides more reliable release performance at all stages of the turn.
