Instead of wrestling with twisted and tangled lanyards while swinging your way up a near-vertical couloir, hook up to the innovative Cassin X-Gyro Leash. The swivel system allows each connection point to rotate independently, eliminating twisting and tangles. Elastic webbing cords stretch for easy swinging and retract to keep excess webbing from getting in the way.

Here's what others have to say...


great idea, imperfect execution

  • Familiarity:I've used it several times

The multiple axes of rotation is definitely better than any alternatives I've seen - it should basically be impossible to get these twisted up (at least on lead, when you are above the rope). The problem I've seen is that the ball/socket joints to make the rotation easier are a little sticky and can lead to twisting anyway.


Awesome leashes

  • Gender:Male
  • Familiarity:I've used it several times

I just finished a week in Ouray with these things. In the past, I've used a janky homemade rig (double-length dyneema slings) as well as the BD Spinner. The X-Gyro is far superior. It didn't get tangled once during the week, both on lead and TR, with a fair amount of matching and other shenanigans.

I'm 6'4" with long arms and the large is perfect. I don't feel any resistance at full extension, but the leash goes completely taut within 12" or so beyond that.

The Biners

The Biners

The attached biners are 2kN-rated accessory biners, not Nano 23.


The best tether

    This is better than the BD tether for a several reasons. First, obviously, it has two more axes of rotation. So not even the webbing itself will get twisted. This is a pretty minor plus, but still. Second, you have the option of girth hitching the ends to your tools, or using the included Nano 23 biners to clip in. So it's also more versatile. It is slightly more cash than the BD leash, but you get 2 Nano 23 biners thrown in. Lastly, without the biners it's actually lighter than the BD tether. And it's rated to the same strength (if that matters). If you are going for simple I'd say make your own or try to get a hold of the Blue Ice tether. But if you are choosing between the Spinner and this thing, get this thing.


    Keeps the tools from dropping

      If you do any multi-pitch climbing then you need a leash. This thing keeps the tools by your side and won't get in the way (too much). Any leash is going to get in the way now and then, but the cool swivel design works so well on this that you won't want anything else. You WILL be happy.

      What is the rated strength of these...

      Best Answer

      Cascade Kid,

      The X-Gyro is not rated for more than bodyweight and it is not recommended to use the leash system to catch a fall. Camp rates the leash for 2 kN, though the included carabiners are full-strength.

      It may be a recent change, but my X-Gyro (purchased on Dec. 2014) came with the 2kN biners shown above, not Nanos.

      On the plus side, you can take the biners out and just girth hitch the loops to shave weight.
