Black Diamond Helio 145 Binding

The Black Diamond Helio 145 is a rock-solid race binding that can be somewhat tailored to your size and aggressiveness. The binding is offered in three release-value settings and has three riser-heights to match your intended usage. Your choice of one of three predetermined release-values dictate the performance characteristics out of the box. The values are determined by a hidden lateral and swappable vertical heel-spring, both made of steel. The heel operates like a typical race binding with a flap covering the pins for uphill, but you can also spin the tower 180° to access a third, higher riser. Moving to the toe-piece, it had half of the wing-springs removed to reduce weight and complexity, but otherwise is a tried-and-true design that has the smoothest lever-action in the business. If you’ve never tried a race binding and are interested in having your mind blown, the BD Helio 145 is a great place to start.

• Your choice of 6, 8, or 10 in release values, both lateral and vertical.
• Roller bearings in the toe offer clean and crisp locking power.
• MonoLink Technology 1.0 removed half the toe-springs without sacrificing performance.
• Flat mode, heel-flap, and reversed heel-flap offer climbing versatility.
• Optional crampon slot takes Black Diamond Helio crampons.

BD Helio 145 / ATK Trofeo - imo, one of the best pin bindings ever made. It's bombproof and weighs "only" 145g, a bit more comparing to other race oriented bindings but it's totally worth the 30g penalty. I'm 192cm tall, weigh 92kg and really abused two pairs of Trofeos during the last two winters. I use 8 spring and it's stiff enough even for very aggresive skiing, binding released only once when I crashed at high speed - toe remained locked though. They are super solid, after two winters (I train on skis 4-5 days a week) bindings still work just fine, no signs of wear or damage.
The only issue I find are the heel flaps which could be designed a little better, there is a bit of effort required to flip especially when cold.

Marek, the heel flap is meant to catch on the U-spring, but you could ease the flap with a bit of careful filing or grinding.

Yes I'm aware of that, just mentioned it because obviously this should be designed better.

Question from Brian L

 

Are the release springs separately available? And are they swappable into any of the ATK race bindings (SL/SL-R)? Was hopping to put an 10 spring in mine (instead of the ~8 that's in there).

Answer from jbo

 

Hi Brian, in theory the release springs are available separately though we have not seen them yet. However, the heel springs are not universally interchangeable and, specifically, the 145 springs will not fit in the SL bindings.
