With a greater clamping force than conventional ascenders, the Black Diamond nForce ascender offers maximum grip on icy or muddy ropes.
With a greater clamping force than conventional ascenders, the Black Diamond nForce ascender offers maximum grip on icy or muddy ropes.
Jug icy, muddy ropes with the Black Diamond nForce ascender that offers 33% more gripping power than traditional ascenders and is capable of driving a climber's bodyweight onto the rope with four-bar leverage for maximum hold. Manipulate the cam with the trigger finger, thumb, or edge of frame while the large grip accommodates gloves.
The Black Diamond nForce Ascender uses a unique four-bar pivot system that places your entire body weight on the cam for excellent grip, even on muddy and icy ropes. The result is 33% better grip than a standard ascender. This same system also reduces cam pressure when you slide the ascender up the rope, which makes the nForce Ascender efficient for jugging long pitches. Because it fits ropes from 8 to 13mm in diameter, this Black Diamond ascender provides a solid choice for everything from big wall climbing to expedition routes on big mountains.
With the nForce Jumars by Black Diamond you get the best grip for jugging icy, muddy ropes (think Denali’s West Buttress or some gnar-ed out fixed cord in the Fisher Towers), the nForce ascender generates more clamping force than conventional designs. The spacious grip accommodates gloves, and a 360-degree biner clip-in point allows full rotation of locking biners.

Easier Trigger Action than The Current Petzl Ascension Design | |
| Rating: |  |
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. | |

| Took a little bit to learn the different mechanics compared to similar ascenders such as Petzl, but after that, you realize the extra effort in the design is what sets these ascenders apart, and the best i've used. -The cams grabbed as advertised(I have yet to use these in wet and/or cold conditions), and released easily. -The teeth look like they would tear your rope up, yet were as smooth as any mechanical asenders i've used. -There was the frustrating "nose-diving", it was remedied by keeping nforce in a strict vertical position while moving upwards, no deviation. -I dropped one about 50 feet, on firm dirt, no problems. The extra moving parts cleaned out easily. -lightweight, extremely strong and stable for all the moving parts, etc, i couldn't be happier.. | |

Nice ascenders. | |

| Takes a little bit to learn the intricacies of these over the Petzl's, but they work very well. At first, when I would pull the cam with my index finger (to lower the ascender on the rope) I would manage to open it completely, popping it off the rope! I've since trained myself to only grab the cam with the tip of my finger, staying away from the cam release trigger. It is nice to be able to open the cam completely with my index finger when I need to. Also takes a little practice to keep it from "nose diving", where the cam will engage while sliding up the rope. Otherwise, I'm sure I will enjoy these beauties for a long time. | |

"Great, light weight ascender, with awesome features" | |
| Rating: | |
| I used this and the right handle ascender on a solo one pitch climb and loved it. The action is smooth jugging up the fixed line, with no immiediate visible wear on the rope, and I was able to clip into the rope one handed with ease. Not only that, but the locker I used was able to reorient itself with out being stopped by the clip in hole. The mechanical parts moved smoothly and seemed burly enough so as to not worry about them. The only problem I had with this individual ascender was that it did feel kind of floppy, more so than the right handed one (manufacturing detail?). All in all a great product from BD! | |

Excellent! | |

I picked these up to add to the gear and the climbing possibilities. Very happy I did! I do like these more than others because of the smooth operation. Even starting out at the end of the rope with a light pull of the "trigger" it glides up the rope nice and easy and locks solid. Have not tried with wet or icy ropes yet, but I would imagine the same performance. I paired mine up with the metolius easy aiders and wow what a perfect combo! | |

Awesome Ascenders | |
| Rating: | |
I bought a pair of these at the beginning of this season, put a few ascents under my belt with them. They do a great job and they handle the rope better after about 15' of height. They are easy on the rope, and are beefier than the alternative name brand. I never regretted buying them, and the chicks like em too. | |

| Been using these for the last two weeks. They work great, look great and lets face it - who doesn't want to own a set of ascenders. I compared them with the petzl's, and I reckon these are much better - more grip and range and the trigger is much easier to use. | |

"Best ascender" | |
| Rating: | |
| The 4 bar system does not only increase grip it also saves the rope - think about it - it would work even without the little spikes. However, if you got a small hand, you got a bit of a problem. | |

| I used this once so far and I have to say that I love it. It's much better then the petzl ascender. I would definitely recommend the nforce to anyone. | |

On one ascender I noticed the cam sticks and will not always lock down on the rope. It's especially bad when the dirt and dust gets into the pivot point. It's never been dropped and its only a few months old. I'm returning these to go with the petzl instead. | |
