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.

Questions & Reviews

Jonathan S (used product a few times)
My new favorite binding for my non-race setups -- all my others are either Plum or a mix of Plum heels and Dynafit SSL toes.
Technically I have the 180, although since I initially mounted it without the adjustment plate, functionally I'm using the equivalent of the 145.
Details at my review of the 180, but everything just works really smoothly (as it should of course), and is nicely refined from ATK's constant evolution of its basic binding design over the years.
The big decision is whether to save $ initially and go with the 145, or spend a bit more on the 180 for all the accessories.

Question from Kevin Woolley
I'm thinking of replacing an old speed turn with Helio 145, will I be drilling new holes?
Answer from jbo
Hi Kevin, for the Speed Turn 1.0, you'll be plugging a hole in the toes and completely re-drilling the heels. More info here.

LCC Skier (used product regularly)
The Helio 145 and Helio 180 are extremely trustworthy bindings that are very lightweight. The changeable release value springs are a great way to reduce weight without sacrificing adjustability, all the while decreasing complexity. I skied the Helio 180 most of last season, and I decided to purchase another pair, just without the plate or crampon holder for a new pair of skis this season. I will say that I somewhat prefer the simpler, more elegant nature of the 145. These bindings have never pre-released for me (I am ~180lbs and 5'11", skiing an 8 release value), and I regularly trust them to hold onto my skis in all but the most extreme falls. Stop reading this bland internet review and get yourself a pair.

Question from Brandon
Do these come with the crampon receptor, or is that separate?
Answer from Teddy Young
Hey Brandon, the crampon receptor is sold separately!

Marek Z (downright abused product)
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.
Reply from Jim
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.
Reply from Marek Z
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.
