Time for a tested, trusted, non-proprietary harness bridge cordage

I would imagine the manufacturer could run into liability issues if they don't give a replacement cordage, or type of cordage, to be used on a replaceable portion of their harness. It also doesn't give a replacement interval.

I don't want a bridge cordage recommendation the NT Onyx manual, I'm just reporting what's there and what isn't there. If New Tribe included a reference to the cordage they use it would be helpful to the Onyx user. Retailers have already filled that gap by mentioning that the bridge is Platinum 10.mm.

But if they don't control the manufactur of the Rope it's just the same liability issue. The Rope manufacturer that they use now and may be out of business in the future. That would put them on the hook for making a spec for a new rope Monday manufacturer. This just gets it off their hands in my mind.

I think these are more problems of documentation/writing continuity. New Tribe could change the bridge cordage for the Onyx at any time for any reason whether Platinum is recommended in their manual or not.
 
NT specifies Teufleberger Platinum 10.5mm cordage for the bridge on their Onyx product page:

I want to put a peice of whoopie sling i got on my bridge connection with a pulley on it i feel like it would be useful but i tried and it really wasnt so idk i still feel like giving it a try again . i got an omniblock i put on and one thats stays on a sling for my rigging
 
Velocity 11mm fits through the treemo bridge holes. If that fits I'm sure a lot of other common 11mm polyester double braids do too. Along with platinum 10.5 with its interwoven core. I just happened to have my factory bridge untied for a minute and a piece of velocity right next to me so I tried it. I will probably continue to use the factory replacement for the main bridge. $20 is fine with me. I use the velocity for a second bridge I use almost exclusively with the captain hook and almost never as primary life support even though I trust it just fine with the knots I tie.

Good to know Velocity fits on the TM. My experience with Velocity is that it has a very soft hand and is not very durable. I like a tough cover on my rope bridge.

My preference is for a bridge that has characteristics equal to 10mm Globe 3000. I guess what I'm trying to say with my original post is I don't want to settle for something that's pretty good as a bridge. I want something purpose designed and built, exemplary for a harness bridge. Teufleberger has done it, looking for something not controlled by Teufleberger. Again, nothing against them, they're doing what they have to do. It doesn't mean a rope manufacturer can't come up with something equally good that could be used as a bridge cordage for the TM and a variety of other rope bridge harnesses.

Might be misreading, you have an omni on your saddle's bridge? And use tenex for your cordage?

It makes sense to want a bridge cord that is purpose built and available in bulk. I think one of the main concerns is the potential for the core to slide out of the jacket, even thru properly tied knots. I think I have seen that happen in break testing. Hence the stitched ends on bridge cords. Teufel's platinum has a locked core by way of strands of core weaving thru jacket I believe. I wonder how stable it is? I wonder what it looks like when it breaks?

Yep, the Platinum is a strong choice. I think that with a 10mm cord like Globe 3000 (when it was available), the experience of many climbers out there is that when the knot is well set, and after a few climbs the knot sets like rock. For the core to slide through, it has to have somewhere to go, in other words if the knot is well set, the cover has to fail first for the core to slip through. I mentioned it earlier but there has never been a report of a climber on a Globe 3000 bridge failing the bridge by slipping the core through a double overhand stopper knot.

All this discussion for a doubled strength rope bridge, that is usually connected to a single strength line and can be made from decades-old 16 strand technology, that even if badly worn, will break anyone in half. If there's a rope bridge problem it's because we've created it.

There is no 16-strand line that I know of that will fit a Tree Motion. Thinking back there is also the problem of OEM rope bridges failing, now corrected (Ergovation?) can't remember. So there are issues around rope bridges, depends on the harness, how the bridge attaches etc.

I agree Richard, this shouldn't be a big deal at all. The usual tension between gear manufacturer liabilities and climber desire to have more control over gear decisions and customization.

Since climbers are the ones actually on rope on a daily basis, we are prone to the kinds of superstitions, myths etc. only partially related to reality. It's like watching the more obsessive/compulsive baseball batters at the plate, the rituals of batting glove adjustment, cup and jersey adjustment are very specific per player but "logically" useless. When a lot is at stake (your life) you tend to drill down on to specific ideas to help deal with that reality whether or not those ideas are actually based on real concepts. The bridge definitely falls into that area. How many of you have been at height in some delicate position, about to perform a challenging task, you look down at your bridge stretched tight, the cordage seems to shrink to a small diameter before your eyes under load. Brief mental note before you start running your saw, "I hope this sh*t holds", and you move on. The bridge is in front of you all the time, it's a psychological vulnerability. And there are actual vulnerabilities with rope bridges, just like everything else in your life connection gear chain.
