Ski Review: Dynastar’s Cham HM 97

 
When you first look at any of Dynastar’s Cham skis it is hard not to think, “somebody was smoking some whacky tobaccy when they made that ski.” Even in an age when traditional shapes and construction are rarely the norm anymore the Cham series draws attention with a tip that more resembles the bow of a boat than the shovel of a ski.

Dynastar’s Cham HM 97. Anarchistic shape delivers versatility and light weight.


In the case of the standard Cham series I tend to agree, but not with the High Mountain versions.

Shano Collins rips it up on Shasta with a pair of Cham HM 97 (and Plum Yak binders).

The performance of the Cham skis is easily derived by reading the profile of the skis construction. As a baseline it is built with sandwich construction on a solid wood core. Interpretation? Between the widest part of the tip, before the shovel rockers up, and the tail, before it feathers down to a pintail finish, every Cham ski in the line acts like a traditional cambered ski delivering solid edge hold on firm snow and stability at speed on firm or icy snow.

My first foray on the Cham HM 97 at Sugar Bowl resort were exactly these conditions. It had been six weeks since the last significant storm and the groomers were firm but confidence at speed was not an issue. The Cham’s held like I was riding on rails. Another run down the steep couloirs under the Lincoln chair proved they held on the steeps and my fears that the huge tip would prove a liability swinging through each turn were unfounded. They were nimble yet secure.

Cham HM 97. Same as the Cham 97 (133•97•113) without the weight of a metal top sheet.


On a follow up run at Alpine Meadows in slightly softer conditions with the Cham 97 again proved the reliability of the Cham 97 profile on firm snow, but the metal top sheet of the regular Cham did add enough weight for the tip of the ski swinging through space to be noticeable on jump turns.

What did not happen, as a cursory view suggests would, is the tendency of the rockered tip to flop in the breeze at speed. It does not, not even with the lighter High Mountain version. Admittedly it can be a liability in frozen crud, but not as much as you might expect.

In softer and deeper snow the tip and tail add versatility to the Cham’s performance. Ordinarily a ski that holds well on firm snow simply dives in soft snow. With the Cham’s Levitation Technology, the huge early rise rockered tip, flotation is mechanically guaranteed. In itself that doesn’t imply good performance in deep snow.

Cham HM 87 (127•87•103), for those who think enough is enough.


That’s where the pintail construction comes in. The common solution is to rocker the tail to allow a ski to release out of a turn easily, but rockered tails suck for earning turns. They make jamming the tail of your ski on a switchback difficult, skins don’t attach well, and make sticking the ski straight down in the snow impossible. By using a tapered width at the tail the Cham HM 97 lets you easily release from one turn into the next, while maintaining simple ski mountaineering functionality for skins, skinning, and rappels.

Does the combination of a pintail and rockered tip work in deep snow? Absolutely. On the heels of the most recent significant dump in Tahoe I took Sugar Bowl’s summit chair to the top of the Judah Ridge. A short, 100 foot walk took me to the cornice overlooking Judah’s east bowl without a single track to spoil the conditions. I dropped in, rolled my knees to turn and the skis took over, floating easily to the top, arcing smoothly and easily transitioning from side to side. I can’t wait to try these puppies in tele mode where they are sure to deliver a smile at least as big as their tips, maybe wider. ;)

Preformed holes in the tips for K2 skin clips, or constructing a rescue sled.

Besides turning performance, the Cham series, especially the HM versions, are particularly adept for backcountry use. The rockered tip is superb for breaking trail, especially when it is deep. The lack of heft in the HM series makes this all the more noticeable. In addition notches are provided in the tail for climbing skin clips, and there are holes in the tip and tail for use with K2′s proprietary tip and tail kits, or for constructing a rescue sled with these skis.

The basic functionality of every Cham series ski is the same, all that changes is the waist width and whether or not it comes with a metal top sheet (the regular series), or without (the HM versions). Personally I prefer the High Mountain series. Not only does the lack of metal top sheet save weight, it also yields a smoother flexing ski for both powder and firm snow. The metalized versions are overly stiff for yours truly, but if you tip the scales near or above 200 pounds you’ll probably prefer the fatter metal versions (Cham 107).

    This ski was one of the big surprises of the year for me. Very strange to look at, but very nice to ski. Lots of touring potential, lots of fun.

    I have some new Scotty Bob tip rocker skis that share a similar tip shape (which is also like the DPS), and the bobtail also achieves the same thing w/o a twintip- you should give them another shot!

  • Prettypants

    A dream backcountry ski. I own this ski with a dynafit binding and could not be happier. The tip profile of this ski helps it to float in powder. But it’s the tail profile that makes this ski a must have. The tail being stiff and powerful makes it predictable and solid for dropping into icy couloirs.

    I first tried the Cham series a few weeks ago but did not get a chance to ski the HM line. I was very impressed by the skis overall, but when I got on the HM 97 the other day I was blown away. The ski is a bit softer, but doesn’t give up any stability at the same time. I felt like there was more even flex, and I could initiate the tip much more effectively. Because of the lightweight the ski felt more playful as well than the regular 97. This is a ski I would def put a Dynafit setup on but wouldn’t turn away from skiing any HM in bounds.

    “I can’t wait to try these puppies in tele mode ”
    Well, did you try them yet?

  • marro.czy

    Will you recommend this ski for telemark? For resort/bc 50/50 would it be better than voile vector?

  • Dostie

    Hold on there guys! I’ll get to it, just haven’t yet. My guess is yes, these rock for tele. Won’t be able to confirm for another week or so since I need to continue testing gear with training heels first. ;)

  • oldnteles

    Thinking tele, what length would you recommend in the HM 97 for someone 5’10″ 165# skiing mainly advanced off-piste in bounds? Thanks.

  • Dostie

    Based on weight – I’d want about 180ish cm of length. However, these ski short on firm snow, long on soft. So 180ish, leaning towards a longer length, like maybe the 185ish version. That also depends on your style, skill, etc. I’m a similar weight and like my skis 175-180cm long, regardless of width or shape. I’d go longer for more hard snow, shorter for soft. That seems counter intuitive, but with hard snow the ski is shorter, with soft snow it acts longer.

  • oldnteles

    Thanks for your thoughts. I ski a 181 K2 100mm that’s fun but too much work for an old guy day in day out (trees & bumps), so thinking about the Cham in a 172. It just sounds short. We mainly ski softer snow so maybe I should just relax and enjoy it.

  • Dan DiMaria

    Did you ever get around to mounting a tele binding on these? Want to mount some AXL bindings on a pair and curious if you have any tips? Pins on chord center? Take into account rocker tip and pin tail when determining chord center?

  • oldmantele

    Have you tried these in tele mode yet? Just picked up a pair (178cm) and want to mount some AXL’s on them. I know the subject has been beaten to death but there’s no center point marked.and the rocker tip/pin tail combo have me wondering. Put them on my bench and marked the contact points at tip and tail but boot looks really far back (at least relative to my old school traditional ski’s). Any suggestions on mounting point? I was thinking I’d go boot center over the alpine center mark.

  • Dostie

    You got it! Go boot center over the alpine center mark. Don’t look back, but do share how it works for you. I haven’t switched mine yet ‘cuz I’m waiting to decide whether I set this ski up for TTS with a Radical, Ion, or TTS toe. Only want to drill one more set of holes so I’m being ultra cautious in my decision.
