No way. v-100 is woven wayyy to loose to be a bridge. You have to cover it.

Now what was this cordage rated at and what diameter/ construction is it? Are you only using one ring on your bridge, or a pulley? The bridge cordage did'nt look like the cover was abused or worn out, so why did the core fail? If it was a factory splice/ bridge, I would definately call them on it! This is not the first time I have seen flaws in factory spliced cordage. I learned to splice my own lines for the same reason. Bend Ratio could be a factor... I know that I run two rings or a pulley on my bridges. The fact that it broke in between the splices is interesting, and by the same token leads one to think that the taper/ splice is stronger and more resistant to bend ratio's than the line itself, or because of the splices the center of the bridge is weakened or takes more load/ abuse due to the excess taper on both sides of the bridge from the splices? Food for thought?

It was 8mm Tech Cord, a 16 strand 100% Technora hollow braid rated at 6200# breaking strength.

Don't know about the rings but the conclusion was that aramid fibers like Technora are self abrasive and that's what led to the failure. Bottome line, don't use COVERED Technora in a sharp bending application because you can't monitor the wear. Vectran apparently doesn't have the same abrasion issues... I'll let you know, I'll be dissecting a Vectran bridge with a year and a half of regular use.

Check this out REVISITED
Hi Guys. I'm fairly new to TB, but definitely not to climbing. While surfing this site, I came across this thread and pictures from last fall, and as one poster said, it makes you want to throw up a little. I am surprised that the thread just sort of died, as there do seem to be some HUGE questions unanswered here. One that was posed and I did not see an answer to was- did any manual (tactile) inspection of this bridge reveal an irregularity of some kind that might have given a clue to this? It seems like it would have had to, but if not...
Also, a few posters referred to some possible inappropriateness of this type of fiber for this application. Any further opinions or info on that?
This was probably the scariest photo I've seen in my short time on TB, again assuming that a proper inspection revealed no signs of a problem. Personally, I have a webbing bridge, but I think there are serious implications here for folks who use rope bridges. Is there any more info on this out there?
