Is my rope safe? (core seems loose in sheath)

Hello!

Yesterday at the gym my belay buddy was holding my rope and noticed that the core of the rope fit loosely inside the sheath (if the sheath is squeezed without the core, you can get an approximately 2 mm pinch of straight sheath). I have never noticed this, so when he pointed it out I was quite surprised. I have a 60 meter, 10.9 mm dry rope (being the intelligent person I am I have since forgotten which exact rope I bought) that is less than a year old. There is no significant ware on the sheath, so I'm wondering if it's still safe to lead with, or if I should get a new one. I'm purely a rock climber, so my rope has never been saturated with water or ice, and I keep it on a flake mat at all the crags. My rope has taken MANY gym falls (all less than 10 feet from the last clip) and less than 10 moderate outdoor falls (10-15 feet from the last protection). Most of the falls have been by people who weight between 130-160 lbs, and a few of the outdoor falls have been by people who weigh around 200 lbs. The rope seems solid, but I've never seen a climbing rope that has the core fit somewhat loosely in the sheath. Also, whenever I climb with new people, they are always shocked at how dynamic my rope is (this has been the case since I bought the rope last July).

Does anyone have any insight? Thank you!!

Nobody will be able to give you definitive/factual advice. However, from a practical stand point you can buy new ropes pretty easily for less than $150, so I would just replace. Climbers are incredibly particular about all sorts of silly things yet many use gear far past its recommended use. At the end of the day its just not worth risking an injury although I would bet a fair amount of money you could take a huge whipper on it and be fine.

Cliff notes- when there's any question about condition replace.

Some ropes are better than others. Assuming there isn't any actual dammage to the core, you just now have a poor handling rope. Who makes this rope, anyway?

When in doubt throw it out

if you have to ask.....toss it.

it is your primary and non-redundant life-saver out there.

Contact the manufacturer directly.

I have never heard of nor could I find any climbing rope that is 10.9mm.. I am not sure where you got this but I highly recommend doing some digging and figuring out what rope it is, and then contact your manufacturer directly.. Until you hear from them, I wouldn't use it.

With that being said when you do remember what rope it is, I'd be curious to know.

Had an Edelweiss that did that. It was a gym rope that we thrashed. Thought it was the gri-gri since I had never experienced that before. Returned it to Liberty Mtn, a local outlet. They told me that "happens". Nate, the employee took it out back and milked the slack out of it and re-trimmed the ends. Never bought another Edelweiss.
