Lately, I’ve been using cheap but flexy $20 Komperdell xc
poles for my backcountry skiing. I don’t have much desire to change the length
of my pole throughout the day. The skinny xc grips are pretty good for plunging
into the snow, and the xc basket and tip provide enough float and don’t get in
the way when I’m scratching across an icy sidehill.
But skimo racing is different. The clock is ticking. Each
time I lift the ski poles up to plant them again further up the mountain costs
me energy. I’m not a double-poling xc skier reaching high and crunching down
low demanding ultimate stiffness, but I prefer not to have to think about my
poles bowing under my measly single pole plants. So I use my trusty Dynafit SR
Race poles. But like any concerning ski mountaineering racer, I’m wondering if
they present the best bang for the buck, and what sort of performance
advantages I can obtain for minimal costs.
Ski mountaineering poles are nothing more than xc poles with
larger baskets and straps that are easy to get in and out of (Leki’s shark
system is also very popular for ski-mo), possibly with reinforcement. One can
buy ski-mo poles off the shelf…er web from Dynafit, Ski Trab, La Sportiva, ATK-Race,
Crazy Idea, Gabel, Komperdell, and Leki among others, but I wondered how the value of these
compared to much more common xc poles, especially if they were placed on sale!
So I looked into the weights and costs of various ski-mo and
xc poles. Many of these weights are claimed, some are verified by others, and
some are estimated by comparing a verified or claimed weight of one pole to the
unit tube weight (g/cm) of a pole from the same manufacturer. The measured and
claimed weights (from skimo.co) were for lengths varying from 125-140cm, so to make for a
fairer comparison of weight, I scaled them (g/cm, including grip/basket,
although actual g/cm goes down as poles get longer). So after checking
Skintrack.com for your optimum pole length, the DyNA will probably be the
lightest out of the poles on this list. Lighter than many $300+ xc poles! Those black diamond traverse adjustable
poles will be more than twice as heavy. Generic alpine poles (Komperdell Carv Pro) are also near the top of the list of the worst g/cm.
XC and ski-mo poles ranked in terms of g/cm (less is better), either
based on measured or claimed weights(at 125,130,135,140cm) or estimated
from the claimed g/cm of the pole and adding the basket and grip
(usually 60-65g). Interesting how there is a slight jump between the
Komperdell nordic classic and the aluminum Dynafit SR Race in the middle of what is otherwise a smooth distribution.
But what poles give you the best bang for the buck? I then
compared the online sale price (retail is for suckers) multiplied by the g/cm.
XC and ski-mo poles ranked in terms of $*g/cm (lower is better). Many
aluminum poles have good $*g/cm as Aluminum is light and cheap! This
high end XC poles have high $*g/cm.
Here
my $20 Komperdells lead the pack. The Dynafit PDG pole seems to offer competitive value and light weight. My SR Race poles give up
~90grams to Dynafit’s best offering. And if you are interested in buying new poles, note that skimo poles like the Movement X-race carbon, Komperdell Nepal 10, Dynafit PDG Expert, and Gabel Piera Menta carbon give you pretty good bang for the buck, along with being pretty light!
What is the relationship between pole price and unit weight? One would expect that as you spend more and more, you are saving less and less weight. This is an exponential relationship and it is plotted below.
But how does ski pole weight affect exertion and overall race times? What about breakage? I've only seen/heard of carbon poles breaking (PDG, RSR, DyNA, "CT1 are too fragile for skimo").
*Updated 2016 with Black Diamond's poles. Vapor 1 and Helio are extremely competitive weight-wise. Will also add Dynafit Speed Vario and C2 ultralight, 2 adjustable poles that weigh ~180grams! Dynafit PDG pole is now the Dynafit Speed pole
