    Big things comes in small packages

    • Familiarity:I've used it several times

    I see why they call it the micro trax now. Very small and lightweight compared to the mini. I grabbed two for some TR soloing and they weigh next to nothing. It's also great for hauling, and can be used if need be for rescue scenarios. It's also extremely easy to use. The small and lightweight design ultimately allows you to save space and move faster which ultimately makes you more efficient. Efficiency is key. One downside is that is doesn't slide quite as smoothly up the rope as the mini did, but it makes up for that in terms of size.

    Versatile tool

    • Familiarity:I've put it through the wringer

    I initially got the Microtraxion to use as part of a solo toproping setup (yes, roped climbing while alone is especially dangerous...don't try this at home), but it has tons of uses. This is a really lightweight addition to a glacier travel setup that could make crevasse rescue much quicker in the right hands (compare the ease of use and flexibility vs having a regular pulley or a prusik-minding pulley). It's certainly not an inexpensive product, but there is a lot of value to be had for the money. While at the end of the day it's best also knowing down to accomplish some of the same tasks with a minimalist setup (i.e. just prusiks and biners), a Microtraxion can really help speed things up and improve efficiency. Two thumbs up here.


      A well built, light, strong and versatile little piece. I plan to bring it along for glacier crossings and crevasse rescue and then repurpose it for some aid climbing and big walls in the spring. I've only been able to do practice systems so far with it but I am already impressed.

      Self-Belay Device

      • Familiarity:I've used it once or twice and have initial impressions

      I was hesitant to pick up a piece of metal that was so expensive, but I'm really pretty happy I did. My primary reason for buying this piece was to use it as a backup fall prevention device in my solo toprope set up, and in this regard it works fabulously. It slides up the rope incredibly smoothly and locks instantly on the way down. It does make me a little nervous that the teeth can be disengaged, but I always make sure before I start a route that I'm good to go, and it's only a backup anyways, so I still feel safe. I've never needed the backup yet (thank goodness) but I have full confidence that it will be there for me if I ever need it.

      The other reason I bought this is because I like MULTIFUNCTIONAL gear. There are many other scenarios where I could use this piece, and as someone who has an interest in mountaineering and canyoneering, I'm sure that one day this piece will accompany me on another trip for another reason. It's expensive, but it's good.

      No Equivalent

      • Familiarity:I've used it once or twice and have initial impressions

      I got this as an emergency piece for canyoneering; and as such, I hope this review remains theoretical.

      This thing really kills it when it comes to ascending a rope. It is so smooth. Also having a progress capture pully will really help if I ever get into a rescue scenario. being able to set up a progress capture 3:1 pulley system could save valuable time.

      This is light and easy to keep on your harness for when shit gets real.

      Petzl Micro Pulley

      • Familiarity:I've put it through the wringer

      Very Small, Very Light!! This is a great little pulley super smooth action. The cam has wonderful teeth for a solid engagement for locking the rope. The cam also has a lock for disengaging the cam all together, so one can use it as a standard pulley. Using 9.6 on this pulley, zero issues.

      Cam locking mechanism

      This shows the position of the cam locking mechanism (the metal strip; my thumb covers the position where you press to lock open). If you bump into this side of the cam while soloing it could lock open without you realizing, so be careful if using the Micro for that purpose.

      Incredibly small

      • Familiarity:I've used it once or twice and have initial impressions

      I got this to test as a possible replacement for a Petzl Ascension as a primary ascender in top rope soloing. When I first received this I was awed at how tiny it is. Pictured below is the Micro Traxion next to an Attache carabiner. It feels bomber too.

      While I don't have much experience with it yet, I can note immediately the issue that has come up with some of these pulleys being used in soloing. Like the Mini Traxion it can be locked in the cam open position, preventing it from acting as an ascender. The way it is oriented when soloing makes it very likely the locking lever will bump your harness. As such I think this can't really replace my Ascension as a primary ascender when soloing. It would be safer to use in the chest harness position rather than attached to the belay loop. On the other hand, compared to the Mini it is much more obvious when it is locked open as the cam sticks prominently out of the casing when opened.

      Incredibly small

      Never leaves my harness

      • Familiarity:I've put it through the wringer

      I have used this a ton, setting up slack lines and Highlines, rope soloing, backup while jugging, hauling and rescue. It's such a killer piece a gear and so small and light that it earned a permanent place on my harness if I'm doing anything other than single pitch. For its size it's extremely efficient and super easy to use.

      soooo useful

      • Familiarity:I've used it several times

      This is a great update on a classic piece. Makes setting up crevasse-rescue much easier, as well as any number of other uses. Being able to release the clamp in the middle of a closed system comes in handy too.

      Used this recently with an 8.1 Beal rope and it worked perfectly. Highly recommend this little guy.

      Easy TR solo setup

      • Familiarity:I've used it several times

      I use Micro Traxion (lower piece) + Trango Cinch on a chest harness as my TR solo setup. Light and easy to setup, glides well, easy to take out before rappelling (do not overweight the rope, full quart water bottle is enough).

      great for hauling

      • Familiarity:I've put it through the wringer

      I'm a huge fan of the mini traxion, so I got this basically the day it came out. Unbelievably light and small, and hauls really well. I have tried to use it for solo climbing on a fixed rope, which is something I do with the mini-traxions, but it does not slide up the rope nearly as well as the minis, so I won't be using it for that.

      Light, smooth and efficient

        This thing rocks! So light you barely notice it is there. I use it mostly for hauling light packs while climbing hard multipitch routes, but have also used it as a soloist/ascender (!!!!WARNING!!!! get proper training for this!!!!!!!!). Very well built, smooth, hauls like a dream even on my thin 6mm static tag line. If you want to save your arms for hauling packs, this is your solution. This would also be a sick addition to a glacier travel kit for crevasse rescue.


          Wall climbing sucks, but the places it takes you are amazing. This little guy not only offers the efficiency of it's big brother the Pro Traxion, but also weighs nothing and racks almost invisibly. I like to use a pre-set ratchet system on walls so having 3 biners and 3 pulleys + cord add's some weight to my rack already on slings. But with this little guy I can significantly reduce my overall rack weight and bulk. Did I mention it can easily haul a grade VI kit 1:1 style efficiently? Yaaaa it's the bomb.

          Also I dropped this thing from 600+ft and it still looks like new. Wow

          Has anyone used the Micro Traxion on a 7.8mm rope? Been having a hard time figuring out an effective progress capture on the 7.8, as a prussik cord thin enough to be effective jams into the pulley and causes all sorts of fun. Thanks!

          What type of rope and size do I get. I...

          What type of rope and size do I get. I want to use the pulley to pull my bike up 2 flights in a brownstone building.

          Best Answer

          You'll need to get a fairly thin rope (<11mm) and you don't want it to stretch, so I'd recommend something in this category ( If those are too long/expensive for you, you can go to a hardware or marine store and ask them to cut a custom length of static braided nylon, but I'd bring the pulley to make sure that it'll run smoothly.
