Liars

The "9 mm" Teufelberger/Maxim Canyon Elite (top pic, and yes I did pull it taught first).

9mm Sterling Canyon C-IV below that for comparison.

Don't you hate that? Actually does make a big difference for me.

Ok so being that I experienced this with some 12 strand dyneema once let me help explain. Rope can be measured two different ways. The first way is to place the rope under 10% load of the maximum breaking strength and measure the diameter while it’s under stretch. That is most likely how the “larger rope” was measured. The second way is to just measure the rope while at rest. This method would make the rope smaller diameter. Some companies are trying for higher MBS, so they will often measure while under load. Some companies are more concerned with weight and material so they measure at rest. Both ways are considered acceptable for standards purposes but as you have seen in your photos, it’s often shocking and somewhat deceiving to think all 9mm ropes are basically the same when they are in fact not.

That makes sense. I figured there were reasons, and the term "liars" was mostly tongue-in-cheek.

However, what does get me a little bit, is that I watched a few different review/comparison videos of that rope by other saddle hunters who listed the specs and were singing it's praises, and I also purchased it from a saddle hunter web store, and nobody in that chain mentioned: "oh, by the way, it's actually a 10mm rope, just FYI"

So the main purpose of this thread was just to alert others that may be considering it.

This is one of the reasons I like Bluewater Ropes more than teufelberger or even sterling. Bluewater measures their ropes at rest so 9mm protac is actually 9mm… my 10mm tethers are smaller than 10mm sterling HTP but have 700 lbs higher break strength

Again, you are a cornucopia of data, the fountain of info for those who care to listen! “tether tight, linesman loose. Tether loose, linesman tight”
