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.

Positive Reviews:

For me big difference between the BD nForce and the Petzl Ascension ascenders is that with the nForce you can pull back on the cam release trigger with either the index finger or thumb of the grasping hand while with the nForce you can only pull back with your thumb, and I found this to involve more stretch and to be uncomfortable with the Ascension. The nForce has a longer cam (more contact area). The Ascension does have a slot up the center of the cam which is supposed to allow mud and ice to exit the contact area between the cam and the rope, but I have never used the Ascension so I don't know how well this works. Also, the nForce has shorter, straight (90-degree) teeth (over a larger area with what BD says is pressed against the rope with 30% more force, when under load, due to the the unique cam action.). The Ascension relies on teeth that are angled downward. Have not tried the nForce with gloves but they are roomier fit. I found the easier trigger action of the nForce to be my main deciding factor.

William Savada at Backcountry.com on 09/12/2009

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!

Got My Vote

Ok. I really tested this ascender with the Petzl and NForce won mainly because it can accommodate a big mitten in winter conditions. I bought both but returned the Petzl. The NForce slid up the rope wonderfully and when the release was activated it provided good descending capabilities. The NForce held my full weight when ascending without any hint of slippage. My only complaint was the descending "knob" which could be operated nominally with the mittened hand but is probably better operated with a glove. I may have to put a lighter glove on my right hand when descendinig the fixed lines on Denali this spring.

at first appraisal it seems really cool. i use it while roofing and it works great for that even with a huge rope, add another and some foot straps and climbing a rope is made easy. the thing i didn't like about it is the little teeth that bit into the rope. i realize it has to grab on somehow but i get the feeling that it is killing the life of my rope. like i said i use it for roofing and when i use the company rope hey i'm all about it, but i don't wanna try it on my expensive climbing rope.

joe4537291 at Backcountry.com on 03/29/2011

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.

Matt Park at Backcountry.com on 09/20/2013

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 !!

Federico Garcia at Backcountry.com on 05/16/2011

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

ganp857122 at Backcountry.com on 02/06/2014

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.

Jeff Guest at Backcountry.com on 06/07/2012

Extremely easy to use. Slides up rope easily, easy to operate after you get used to it. A little bit heavier then other ascenders, but I find it to be the safest ascender out there, and the carabiner hole at the bottom allows for 360 degree rotation of even large locking carabiners. Great plus

Brian Muller at Backcountry.com on 12/01/2009

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!!!
AWESOME

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