Goode 95 172 cm Skis

A friend brought a beater pair of Goode 95s by for a mount on the mill. The skis themselves are in great shape, but they’re on their third or fourth mount. Skis have six inserts/ski for tele, and we added eight inserts/ski for La Sportiva bindings. Skis have had other holes filled (or not) with JB Weld.

Skis are stiff, minimal camber. The contact points are quite close to the ends of the ski. Looks like a very traditional design, and may be less forgiving of technical error than some modern skis.  Torsional stiffness is excellent; I’d expect it to hold an edge well.



For these skis, after calibration and unbiasing, I measure 1256 ± 40 grams . Individually, they weighed in at 1279 and 1234 g.  While these skis are holey, I’d be surprised if all 45 grams of difference between the skis is due to their post-sale history. 45 grams is a lot – almost two ounces. But, without a pristine pair, we cannot be sure.

New skis would be somewhat lighter, perhaps 20-30 g. Each ski has 17g+  of inserts alone.

Swix RC140 Skate Poles (170 cm)


Got schooled by the kind and knowledgeable folks at Marmot Mountain on the ins and outs of skate poles. Considering my budget, the mid-grade Swix poles seemed to strike the right balance. These are the ones with the blue hatching. Definitely found the middle ground in stiffness in the Swix line, but seemingly stiffer than the full-carbon Yoko pole of the same size.

Poles weighed in at 261.6 and 263.3 g, so 262.5 ± 1.5 grams (with usual caveats about measuring errorbars off two points). Couldn’t find a Swix spec for the poles’ mass.

Fischer CRS Skate Vasa 192 cm




The skate gear continues. As a review goes, I’m still calibrating myself as much as the skis for skate gear. No flaws, binding mount went smoothly, skis go fast.

If you’re looking at the photos, the 2000/2006 g calibration factor applies to this scale. One ski weighed in at 700 g, the other at 708 g. With the usual caveats (2 measurements is a poor way to sample a distribution),  this comes to 704±7 grams for each ski. I can’t find a spec from Fischer for the 192 cm ski.

Rossignol F4 Skate NIS Binding

Skate gear is starting to cross the MeasuredMass scales. Once these bindings get some snow time, I’ll post a review. What did they say on the scale?


121.0 g and 121.3 g, respectively.  Two samples is too small to reliably estimate an uncertainty, but if I do, it’s 121.15±0.27 g.  Rossignol quotes 240 g/pr, so these might be less than 1% high, but without an uncertainty from Rossignol (depending on significant digits, that 240 could be 240±5), it’s impossible to tell.

Looking forward to getting some time on them!

ACR ResQLink

I’d been thinking about a serious rescue beacon (PLB) for a long time, perhaps leaning toward the DeLorme InReach, when the ResQLink arrived under our tree. The two-way communication feature was very attractive, but the requirement of a (hardly rugged and heavy) smartphone and the substantial subscription fee kept me from buying in.

We decided not to let the perfect in the way of the good, and I’ve kept the ResQLink. The NOAA registration online was quick and easy.

It’s though, and weight matters on a device like this. It’s really just dead weight; unless you’re almost dead, then it’s useful.  The box and website claim 4.6 ounces / 130 grams. What does it say on the scale?


143.8 grams (or 5.1 oz). That’s 11% high. Without more samples of the device, I can’t comment on product variation. The strap weighs 1.8 grams, so that isn’t the cause. For a product whose weight is an important feature, even 9% is a lot.

Rossignol X-8 Skate Boot, 48.0


A pair of Rossignol X-8 boots came through today, just in time for the beginning of our cross-country ski season. A fit comparison with the Fischer RC3 (matching pricepoints at REI) found that the X-8 fit was somewhat wider and softer in the forefoot at equal size. The boot is soft-enough that it’s instantly comfortable.

Haven’t had a chance to get them on snow (edit: they ski great!), but it was easy to get them on the scale.

Black Diamond Neve Crampon


Aluminum crampons are great. I’d shied away from them after a friend advised, “When I really need crampons, I really want steel.” A couple of years later, my awesome girlfriend (who was tired of waiting for slowpants) got a pair for my birthday. They get the job done.

As important as climbing ability is their light weight. The Neves are 52% of the weight of my venerable cro-moly Sabreteeth; more than a pound lighter. The weight advantage makes them easy to bring along when the need for ‘pons is uncertain. I’ve used them on half the trips on which I’ve carried them; such was the summer in the Cascades.

The aluminum points stand up much better than expected to alpine rock. They wear and flex, but not quickly nor easily. While their forte is softer snow, when sharp they worked well on glazed autumn melt-freeze. They fit Mondo 30 ZZeros, Dynafit ONEs, and La Sportiva Trango S well, with room (!) for adjustment. The weights quoted here are, due to a little wear, slight underestimates of the weight when new. I’d guess I’ve worn 0.1-0.2 g of aluminum off each foot. There may be some dust in the straps, but not very much.

The weights/masses: 294.2 g for one, and 294.5 g for the other. Roughly 588.7±0.5 grams/pair.  The Black Diamond web page claims 576 grams/pair in December 2012. The pair weighed here was purchased in Autumn 2011; I can’t find a product page from 2011 for comparison. If the crampon/hardware is unchanged, then the product weight is 2% higher than advertised.

Binding Freedom Inserts


I headed up to ski today, but arrived at the gas station halfway there without a wallet. I had enough gas to get home, but not enough to ski, so it was off to the lab/shop for some ski work.

I’d played with a set of Binding Freedom inserts last season, remounting my very first pair of skis with inserts as rock skis. I’ve now drilled my Kailas and Sahales (whence the bindings came) for the inserts, and glue is curing in the Kailas. As I was cleaning up, I realized that my remaining stash of inserts would provide a nice example of how to  determine the uncertainty in product weight.

Dynafit ONE PX TF 30.0


Christmas in November! When ZZero PX boots failed under warranty, Dynafit/Salewa sent a pair of the new Dynafit ONE PX as a replacement. Stoked.

Finish and mechanical quality is excellent. Boots are comfy and solid around the house. Palpably stiffer than the ZZero PX, but the walk mode is superior to the TLT4. I anticipate that these boots will ski well.
