A revolution in big wall climbing.

The Black Diamond nForce Ascender uses a unique four-bar pivot system that gives you a 33% better grip than a standard ascender, and it comes packed full of features that make cleaning pitches easier than you ever thought possible. A unique trigger-actuated release makes it easier to slide up your bottom ascender when you're low on a pitch and you don't have any rope weight to help you yet. Since the nForce Ascender works on ropes all the way down to 8mm, it also makes a solid choice for expedition-style mountaineering with fixed ropes. Whatever you need it for, this ascender has you covered, and then some.

  • The four-bar pivot system places your entire body weight on the cam for excellent grip, even on muddy and icy ropes
  • This pivot system also reduces cam pressure when you slide the ascender up the rope
  • Fits ropes from 8 to 13mm in diameter, which makes it ideal for big walls and mountains
  • Large clip hole lets you rotate a locking carabiner 360-degrees if needed
  • Quick-release trigger makes cleaning tricky traverses and lower-outs easy
  • Large ergonomic grip for dexterity

safe and secure

  • Familiarity: I've put it through the wringer

easy to operate even with gloves or mittens on, never had any problems

Solid ascender

  • Familiarity: I've put it through the wringer

These things are a very solid ascender and work very well. They are a solid competitor to the Petzl and worth a serious look.

Sweet Ascenders

  • Familiarity: I've put it through the wringer

I had a set of Petzl Ascensions and switched to these and will not be switching back. It is so much more convenient that you use your index finger to operate instead of your thumb. The only down side is that if you have fat fingers and are wearing gloves it is a harder to work the trigger

Decent at best.

  • Familiarity: I've put it through the wringer

These jugs are the definition of over engineering. Linkage, and tons of moving parts combine to make a messy jug.

best ones out there

  • Familiarity: I've put it through the wringer

very confortable to jug with. an advantge over the other ascenders is that the biner loop is big enough to get the srew-lock throug.
another advantage is that it still works with frozen and dirty ropes

Jug heaven

  • Familiarity: I've put it through the wringer

The boys at BD were thinking when they made these. the ability to disengage the cam with your index finger is the best. sounds whimpy but after a while with the petzl ones my thumb got sore from bending at that angle so much. also I have huge hands and these fit in my hand way better than the petzl. from my observation these don't damage the rope as much as the petzl since the teeth are less aggressive. basically when you have to jug all day you will be glad you got these.

BD ascenders

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

Has everything you need in an ascender, but the ability to disengage the mechanism with the index finger is what swayed my decision to the BD rather than the petzl.

Slightly heavier than the Petzl Ascenders

I have used these BD Ascenders and the Petzl Ascenders. I really can't decide which one I think is better between the two but I have noticed that the Petzl Ascenders seem to weigh slightly less than BD. They are basically the same price too! If you are concerned about weight then I would go with Petzl.



Responded on

If you are looking to use this as a self belay on a fixed line that is NOT advised as there is a very real possibility that you will shear the rope and lead to serious injury or death. You would want to look at a Soloist device for that purpose.

Get On Up

From bigwalls to high angle video shoots these have been my go to ascenders, and they have seen some serious miles. These are faster to take on and off the rope then the Petzl's and I feel like you can move up the rope a tad faster as well. Also, they are indestructable!!!

Best Ascenders

I have used my BD Ascenders multiple times and I love them! They are easy to put onto the rope and for the most part easy to take off the rope. They do kind of make your hands tired so make sure to wear gloves while ascending. I if you take them canyoneering, be sure to keep them in a dry bag to keep the sand off them as the sand will make the pivot joints not work so well, but you can wash them out with water. I've climbed 400ft of rope in one session and have only had a few times when the teeth didn't grab the rope, but it was rare and didn't bother me that bad. I would for sure recommend these ascenders to anyone!

Awesome Ascenders

Who would have thought that climbing gear could be sexy? These are smooth, strong, and a breeze to go up the rope. I use 9.8 mm rope and BD mini pearbiners to lock on foot tapes. It's like climbing a ladder only more fun.

BD Ascender?s do the job !!!

These ascenders are great they slip very well on the rope, work on ropes from 8 to 13 mm, are light weight and ergonomic, and the switch is just simple and easy to operate, the only problem that i see is if you take a very strong fall the little teeth could really harm your rope, not really sure but it could happen, but right now these are just the best !!
