Cam locking mechanism

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.

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.

Wow, what a difference!

Had the pleasure of training with this piece over the weekend. This little guy makes setting up crevasse rescue much easier. Hauled like a champ in a drop c system.

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.

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.

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 (http://www.backcountry.com/static-ropes). 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.

Easy TR solo setup

  • Gender: Male
  • 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

  • Gender: Female
  • 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.

thanx steph! i've been debating between getting the micro or mini for rope soloing. i'll go with the mini :)

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
