    Versatility at its skinniest.

    Sterling's Fusion Ion R Bi-Color Climbing rope is strong for sport, light for multipitch, and reliable for terrifying trad climbs. Its 9.4mm diameter is an excellent starter for using skinny ropes, and multiple colored fibers give the sheath a speckled vibe. A bi-pattern design adds convenience when it's time to rappel.

    Nice do it all Rope

    • Familiarity: I've used it once or twice and have initial impressions

    Nice rope for a fairly thin diameter. Initial impressions: Quality seems high, good soft catch, bi-pattern is always a nice plus. I would reserve this for trad lines and multi pitch routes. It is a bit thin for hanging on it or doing a bunch of sport route jugging.


    • Familiarity: I've used it several times

    It seems okay. I bought the bi-pattern which comes in handy when trying to find the middle marker as the sun goes down. Doesn't feel as thin as it says, I am curious how it holds up, I replaced a sterling velocity with this guy.

    very low sheath durability

    • Familiarity: I've used it several times

    I got this for a second rock climbing rope - trad + sport. After 10 days of use - and no TR-ing - the rope was fraying and looking like it was years old. The slippery sheath was gone and it then attracted dirt like no rope I have ever owned (20+ yrs of climbing). After washing it, even after one day of use - like 12 total climbs (6x2 clipping bolts) the rope would get incredibly dirty with the fuzzy dirt-attracting sheath - from aluminum of beners and if the pulled rope misses your rope bag tarp - the dirt was embedded instantly. I would absolutely use any other manufacturer's 9.4 over this one. No way one could even think about climbing ice with it as it would be a sponge for water (much less if it would be set down on snow) with zero slippery sheath after several days out. Not recommended

    Pros: The rope handled like a champ when it was brand new for the first 2 times out
    Cons: worst durability I've ever seen in using well over 20+ ropes extensively.

    love it

    Sterling fusion ion rope, 9.4 mm five stars !! This rope is the rope of all ropes! It's durable, supple and lightweight. it is ready to go right away and doesn't take time breaking it in nice red color I'd recommend this rope any day of the week....

    A good rope, but lacks some durability

    • Familiarity: I've put it through the wringer

    I got this rope as a middleweight between my 9.8mm workhorse and my 9.0mm sending rope. Perhaps my error was treating it too much like a sport climbing workhorse, but after only two weekends of moderate projecting and whipping at the New River Gorge (~6 climbing days), the sheath began to show significant signs of fuzzing and wear. This is a little disappointing, considering that I'd gotten the bicolor specifically for a winter trip to El Potrero Chico.

    I had the predecessor to this rope, the Fusion Ion2, which had similar wear issues. That rope also lasted less than a season. Admittedly, I work my ropes hard, but it was strange that my Sterling Nano 9.2mm seemed to hold up better with the same usage (my Evolution Velocity 9.8mm has been chugging along for multiple seasons, though that's to be expected).

    Otherwise, the handling is great, the catch is soft, and the bicolor is easily seen, even in the dark. I gave it four stars because I suspect that I've been using it for the wrong purpose - I think that for something like multi pitch trad, where falls are less frequent and the wear is distributed along the length of the rope, this rope would be great.

    Fallen in love.... Fusion caught me

    • Familiarity: I've put it through the wringer

    As you can probably tell, Dan Gates and I have been getting after it on some super gnarly 5.8 trad routes. Watch out Hard Men, here we come.

    I don't mean to be a broken record, but I really agree with everything Dan has said. The first time we used the rope we said the exact same thing "I love this rope". When I climbed with Geoff Conner in City of Rocks, we said the same thing.... "I love this rope".

    The rope itself is a great do-it-all rope for trad and sport climbers alike. The only thing this rope wouldn't be great for is all-day top-roping. 9.4mm is light enough to hike with on long approaches, but you're not going to blow through it in one season sport climbing either. The rope itself is easy to knot, clip, and belay with. As someone who is colorblind I absolutely LOVE the bi-pattern scheme on this rope. It is VERY easy for me to see the middle of the rope, whereas some bi-color patterns are very difficult for me.

    I've used this rope on short and long routes with 4 minute approaches to 4 hour approaches, trad, sport, and gym.

    This rope is definitely your ticket on the send train.



    Killer Trad/Alpine Rope

    • Familiarity: I've put it through the wringer

    The Fusion Ion R Bi-Color is one of the best ropes I have ever used. I am normally a die hard Mammut fan when it comes to ropes, but this rope changed my mind. 9.4mm is a great diameter especially in the 70M length. It is light enough to take into the alpine, but durable enough for epics in rough terrain.

    The rope is supple and easy to clip and belay with. The bi-color pattern makes setting up rappels and gauging distance on combined pitches super easy.

    I can't think of a better rope for multipitch, trad, and alpine routes. If you are an experienced climber looking for a light weight workhorse, congrats you just found it.

    If you have questions on ropes or this rope specifically please let me know and I would be happy to help.

    The rope!

    • Familiarity: I've put it through the wringer

    Great rope. The bi-pattern makes multipitch climbing simple. The rope handles great and doesn't twist like other ropes I have owned. Sterling is hands down the way to go!
