    The biggest Pinnacle, the 118, is the pro model of some dude named Seth Morrison, and its little bro the K2 Pinnacle 105 Ski rips just as hard but with a slightly different quiver-of-one design that will slay everything from champagne pow to tight trees to steeps that'll have you puckered. The whole Pinnacle lineup is based on K2's Baseline 2.0 technology, which matches the camber and sidecut profiles to provide turning characteristics, float, and flex that perfectly match each other. In the case of the Pinnacle, the gradual tip rise of the All-Terrain Rocker works with the slightly tapered tip shape to give you smooth, hook-free float in soft snow, while the tapered and blunted tails work with the low tail rocker to give you powerful finish through turns and the ability to throw your skis sideways when a pow slash is in order. There's a moderate amount of sidecut underfoot, which works with the medium amount of camber to balance edging performance and float without being overly aggressive in soft conditions or sloppy when things tighten up a little.

    The Pinnacle's shape is cutting edge, and the materials its made from are right there with it. It's not often that you come across a high-performance and powerful ski that has composite insides, but K2's Konic Nanolite core combines a stiff and powerful aspen perimeter with a lightweight and forgiving Nanolite composite in the center, giving the Pinnacle a hard-charging feel that's quicker and easier to ski than boards with full metal laminates. Don't worry, though, the Pinnacle does feature a springy and damp metal laminate, too, along with a triaxial braided fiberglass layer that gives it the strength to stay straight under serious edging forces. K2 covered up the core with its HybriTech half-cap construction, which uses edgy and powerful sidewalls under the cambered section and sandwich construction in the tips and tails to encourage smooth engagement into turns and keep swing weight to a minimum, so you can get jibby and snake your way through tight spots like you didn't even notice.

    Magic Boards

    • Familiarity: I've used it several times

    Just made a trip where I would have had a $200 bag fee each way so I decided to demo a similar pair of boards (Salomon QST 106) and I was missing my K2s the whole time. From the first morning with fresh legs and fresh snow where I felt the Salomons didn't feel as bouncy and light in ankle to knee deep fluff to the cruddy, crusty mess of 3 afternoons later where the QSTs felt slower edge to edge and didn't seem to grip on ice any better than the k2. The Salomons may have felt a little damper at super high speeds on hard snow but not by much and with a way stiffer, less surfy feel. Can't wait to get some more days in on these.

    Just Plain Fun!

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

    I have not skied on K2 Skis since 07-08ish (maybe earlier?) when I bought the Seth Morrison Pro Model. Loved that ski but, out grew it after moving to Utah. Bought K2's new Spyne LV 130 Ski Boot and was beyond impressed so I had to give K2's entire line a shot. Please dont hesitate to contact me with specific questions regarding K2's line, I would be happy to help!

    I was able to try out the new Pinnacle from K2 at the Outdoor Retailer show and like the boot was really impressed.

    I am 5'8" 200 lbs and in the 184cm length It was one of the quickest skis edge to edge I tried out around that length. It felt like a slalom ski, when I brought them back I guessed the turn radius to be like 15-16 m, surprised to find out it was 19 m. I felt like the ski could turn a lot shorter using only the edges.

    The ski isnt super stiff. I prefer a stiffer ski to get the edge hold and stability through the crud. I felt the ski deflect a little in the crud but, I am heavy and I was moving very fast. What impressed me was the edge hold.

    Usually my brain shuts down when people start talking about specific technologies in a ski. I need to feel it to believe it. The Konic technology though is legit. You can definitely feel the increased edge hold due to the construction of the ski. The engineers came up with a way to drive the force from the boot to the edges and it was definitely noticeable.

    The ski's weight does not put it into the super light category but, its pretty dang light. I would totally put a Marker King Pin on this and use this ski 50/50 in bounds out of bounds.

    Again, if you have any questions like:
    -What Binding Would go Well with this?
    -Is this a good back country ski?
    -What length should I get?

    Please contact me via email or my direct phone line which you can find right above this review.

    They do it all.

    I hopped on the Pinnacle 105 during our Spring ski test at Alta, UT. The conditions started out with frozen, difficult conditions but warmed up as the day went on. Unfortunately, the Wasatch was particularly dry last season so I did not get to test them in the deep soft snow of winters past.

    I found myself not wanting to bring the skis back in because they could hold an edge on the frozen hardpack, were quick and powerful in turns, and could blast through crud while remaining stable thanks to their triaxial braided fiberglass and metal laminate. They are a tad lighter than last years Annex 108, thanks to the Konic Nanolite. Due to this the swingweight is lower which you can really feel when needing the skis to be nimble.

    I truly believe this ski can do it all and look forward to getting on a pair during a storm day.

    They do it all.

    Anyone know the weight of these? I tour on some older K2 Side Stash's.

    Best Answer

    Backcountry magazine 2016 gear guide says 7 lb 14 oz in the 177 cm length. If accurate, this is approx 100 gr or 4 oz more than the Volkl carbon 109, and same as the K2 114 Coomback. Interesting, and not bad for a ski with laminated metal. Love the way the Sidestashes ski BTW, but heavy for touring. should include weights of all skis in lbs and grams.

    I've got a pair of these mounted up with 22-design axl's and they are beasts. I'm unable to accurately weigh them on a food scale but mounted up one of um (184 length) is about 7.5 pounds (my weight with/without the skis on a .5 resolution normal scale). Not my first choice for touring around, but they will take you on a crazy ride through the crud and funk that a lighter ski might get tossed around on. Also worth noting that these 184's are a good couple inches longer than other 184's I have (DPS wailers and some older G3 spitfires). They are just all around beasts. For me at least a ski like this really wants to do the driving, so the posted turn radius (19meters) gives a good idea about how they run. Noodling around in the trees with these skis is a lot more work, but carving big GS turns through whatever is out there is super easy.
