Sliding rope Harness - What if we used 3-5mm steel rope instead.

Postby DalexRitch » Sat May 21, 2022 11:45 am

I have an old Ride Engine harness I'm using as a Guinee pig for some projects. Have already made a GoPro mount on it to store my mouth mount when It gets tiring - next idea is to swap out the rope on sliding rope spreader bar for a similarly sized piece of stainless steel wire, and somehow clamp both ends on the back of the slider so they don't pull through. I have the duotone click bar with the surf loop, so it would be metal sliding against metal. Anyone think this is an obviously stupid idea or would present challenges? Any ideas are appreciated, Thanks!

I think your idea's primary advantage would be less friction on the slider, so the mechanism would feel much smoother as the slider moves along the steel "rope". I'm sure that's your reason for making the switch. Let us know how that goes.

The only downside I can imagine is that the steel "rope" will be more abrasive to a body part that scrapes across it (e.g., in a crash). I'd also be concerned about individual steel strands breaking to form those painfully annoying pin-like ends that appear on worn stranded wire. Once a few strands break, you'd probably have to replace the wire, even though it still has sufficient strength (maybe sooner than you'd have to replace a true rope slider). Might still be a good idea to test.

It might create a horrible metal-on-metal noise when it moves around but I guess you will only know when you try.

Other considerations:
* Rope is weaker then the surf loop so the rope wears instead of the loop. With a “metal rope” you might wear down the (more expensive) surf loop instead of a cheap replaceable rope.

* Salt water requires “marine grade” metal. Regular stainless steel will corrode so make sure it’s marine grade


All in all I am not convinced it would be an improvement compared to a rope and you are adding some risk by creating an untested setup. Who knows at what force either the metal itself or the attachment to the harness breaks….

I have had my dynabar for almost 10 years. Works great , bomb proof.

Take a look at Mammut’s Magic-Sling. I’d like to experiment with this. Based on its unique construction, it seems perfect for both strength and durability for kiting applications. You can even tie a knot in it with limited compromise to the strength.

The potential for injury from a single strand failure is more than enough for me to regard the use of wire as a bad idea. Seen nasty cuts and gouges from yacht rigging. If you want something long lasting use 5mm dyneema with 3mm insert and then use a roller hook or shackle as the runner. That will last for years if the spreader bar insert hole is not sharp. Don’t make the runner angle too shallow or you rope lever too much tension into the runner.

4mm dyneema and a thick climbing ring works great and has low friction:

^^ That would work too, but maybe a little more wear than a roller imho but maybe with less length introduced. On my dynabar I use 4mm dyneema, loop at one end for a release pin and knot at the other. The bury goes full length for redundancy and is part of the knot. I stitch the knot as insurance. ( Probably a close run thing on all the different surface wear rates depending on quality etc! )

Nylon top hat collars/rivets are or have been available on eBay to line spreader bar holes! May need 4 rather than 5mm dyneema to have room for tophat liner etc……
