Awesome comparison. Thanks the thorough work you do!

Thanks Yann. Been looking forward to this device.

Yann, Thank you so much for this video. I decided to buy the Micro Traxion after your review.

Perhaps im a little late to the party, but thank you for the video and all the information and time you put into this. I like to research things and weigh out what the best option is before purchasing something and this had everything i would like to see in it. Thank you very much!

Great comparison! Thanks a lot

You have a cool accent. Half the time it sounds like a French accent and then the other half of the time you sound like you have a perfect American accent.

Great comparison, thanks. Happy you covered the cord thing, and you just taught about that trick for letting the MT on while rappeling, thank you!!!!

Good video, thanks. Can you do a review of the DMM Buddy?

Basically seems like the nanotrax is ideal for skinny ropes in glacier travel / crevasse rescue / ski mountaineering where weight is really important. Otherwise if using a rope >9mm (most singles for rock climbing) or wanting the option to use it without the progress capture disabled the microtrax seems better. I'm not picking up the nano trax anytime soon, already happy with the micro for all uses from glaciers to rock.

Alternate these videos. Huge knowledge dumps and l scooping them up 👍

What a great comparison Yann! Nice! About the pulley size. Yes bending/reforming is resulting in drag. Bit also the shear size of the pulley. You might want to think of it as, removing a wheel bolt from your car. With a small wrench (small radius of pulley) or a 50% larger wrench to overcome the friction of the bolt. The Nano is 18mm and the Micro 27mm. exact 50% larger. and so 50% more easy to overcome the friction of the bearing. Not ones, but continuous. Next to that the smaller Nano must turn (and overcome that friction and bending rope) 17,7 times and the Micro 11,8 times for 1 meter of rope. One note to the stronger spring in the Nano; my guess is that de radius of the Nano is smaller, so the contact surface of cam/pulley is less. Therefore it must grab for sure, which a stronger spring can do.

Could the spring tension be due to micro trax is a used device?

Excellent

I have 2 nano traxes that are around 2 years old and I have done a lot of soloing and belaying on one of them. I just bought a micro and it definitely has a weaker spring

I ordered mine nano traxion already 6 months ago. Should arrive in the next two weeks. I‘m really curious how it compares in rescue situations

Looks like the Edelrid Spoc. How similar are those two? Do you have them both?

I received the following comment from Craig Spaulding of SICgrips: Since the Microtrax release cord was mentioned in passing, I thought I would address it here as a comment. There have been three complaints made by arm-chair climbers and gearoom “test-pilots” who’ve never tried the RIPcord Release. I’ll address each of these. I want to be clear - none of these have been observed during my year and a half of use. 1. “Cord will get entangled in toothed cam and prevent it from locking up.” This is pretty much impossible to happen since it is not a dangling single cord that can get flipped up into the cam. It is a short loop that’s on the back side of the cam away from the teeth. 2. “Cord loop will get caught on something to prevent it from locking up.” Unless you’re climbing in a brushy/bushy area, there is nothing for it to get caught on. The loop is on the backside of the MT/NT facing the body between your legs and it is vertically oriented, not horizontal like a lasso. 3. “Cam teeth will rub on rope while rapping causing it to snag and rip sheath fibers causing extra wear.” Take a look at the photos in my blogpost. There is plenty of clearance between the pulled open cam and the rope when rapping. If you use an older fatter rope, then it might be possible. I’ve used this mod with ropes that are 9.4-9.6. If it does snag the rope, then it’s going to lock up just like in a TRS “fall”. Once the teeth initiate the lock up, it’s the cam action that pinches the rope and stops movement, not the teeth. Again, I’m not trying to convince anyone - just trying to share info based on my experience. If your “inner climber” is paranoid, by all means don’t use it. However, if it looks like something that might be useful to you, then give it a try and make your own observations. This mod is is for MT/NT backup use and is fairly easy and safe to test by implementing before grinding off the lock-out nub. YMMV. See sicgrips.blogspot.com/2021/11/ripcord-microtrax-thumb-loop-for.html

Just curious have you tired the nano traxion with the grivel clepsydra? I’ve Been using combo for top rope solo(backed up w micro traxion) just wondering if you see any issues or potential problems

Any more updates on the friction..? thinking about getting a Nano but wondering about the friction on my 10.5mm static, the Micro I have works great paired with a handled ascender as back up (using this as I had it already). Wanting to upgrade my back up to something else, possibly nano..

Looks very interesting for crevasse rescue?

The nano lacking the cam lock is a big drawback, you no longer can use it as a pulley. (it also sounds like the heavier cam spring will cause a noticeable increase in rope jacket wear)

the rating is weak. Toothed cam is BS. Is there a better version of Petzl Shunt? I like it but as we know it's not perfect

Size matters, i knew it!

No way to disengage the nano → how do you do on the way down when TRS'ing ? You can't just let it hang, you have to remove it !… → too cumbersome for laps !

I don't like the idea of a second drilled hole in the carabiner. One is enough.

For TRS im not sure why the nano would beat a Ropeman 2.

Id be interested to see how the Nano Traxion slides on the thinner rope, like one between 8mm and 9mm. Would the Petzl OK fit well with the Nano Traxion?
