Åsnes NOSI 76 Ski Review

Very !

Are these both the previous-gen Nosi- not the "new" Xplore version?

Is it possible that your used 172 Nosi has lost some camber height from use?

Curious- does the 180 Nosi have more shovel rocker than your 180 Storetind?

Yes both are previous gen skis. I did not want that groove and I like more the old top sheet desing. Therefore older version. Anyway, as I know there should not be any other differencies bethween the versions.

I would say the rocker-camber-rocker profile of the 172 Nosi looked the same when they were new.

Nosi has quite a lot more rocker than Storetind. Storetind needs also about twice as much force to compress flat. There is also more taper on the Nosi at both ends.

I ended up mounting the bindings pinline +1,5 cm from the BP but visually it still looks like the bindings should be even more forward.

Unfortunatelly it will take some time before I will have a possibility to test the longer Nosi. Worst winter for years here. There is no snow at all in the southern Finland at the moment. We are going to Lapland at the end of next month so most propably it will not be until that.

Excellent photos- thank you for posting them!

That looks to be the same generation Storetind Carbon that I have.

Curious- with the ample rocker on the Nosi- why would you want a more forward mount?

With rocker- doesn't one inherently end up "further forward" on the effective edge/running surface?

Is the boot-center mark on the ski placed at the center of the parabolic sidecut, or the center of the effective edge/running surface?

Looking at your comparison of the rocker-flex pattern of the Nosi Storetind, my initial inclination would be to be further back and more centered on the Nosi...

@lilcliffy, no problem you’re welcome!

About the binding position: that was only based on my intuition when I compared 172 and 180 Nosis. Comparing to the shorter one the 180 cm Nosi extends quite a lot more to the tip than than to tail (from the boot center mark) and there is less tail rocker. Ofcourse I can’t say anything sure before I have skied also with the longer one.

Anyway basically it depends what you want the skis to be. Move the bingings back if you want skis that are more stable at high speeds. If your skiing is carving with a lot of pressure at the front of ski, move bindings back. Move the bindings forward if you want skis that are easier to turn at low speeds and easier to initiate to a turn on more consolidated snow or harder surfaces.

My xcD skiing is never going to be high speed charging. Neither it will be real carving because of the binding/boot combo. The more width and the more length a ski has the more power is needed from the bindings and boots to control the ski when the conditions are less than ideal. With more forward binding position you can make longer skis feel more agile.

Also when you are opening a ski/skin track in deep soft snow the tails tend to dive deeper because there is always less floatable surface at the back of the ski. By moving the bindings more forward the skis will float more horizontal.

I did not measure the boot center mark vs center of the sidecut or effectice edge but with a EU43 sized boot the boot center is a few cm back from the boot center mark on the ski when the pin line is +1,5 cm from the bp. I didn’t measure the exact difference but I can do it later today.

To continue: The 172 cm Nosi looks proportionally really good and it also skis really well. I have the bindings mounted pin line +1 cm from the bp.

172 cm Nosi’s true tip to tail length is 170 cm and the boot center mark is 75 cm from the tail (= -10 cm from the true center). 180 cm Nosi is 178 cm and the boot center mark is 77 cm from the tail (-12 cm true center). There is 6 cm more ski in front of the bindings if they are mounted to the same position compared to the boot center mark and only 2 cm more ski at the back.

Bp vs boot center mark difference is about the same on both lengths. When the pin line is +1,5 from the bp the measured center of 43 size Svartisen is about -2 cm from boot center mark (180 cm ski).

The 180 cm Nosi is about 1,5 mm thicker at boot center mark so it must be atleast somewhat stiffer too.

So visually those two lengths have quite a different dna, the shorter beeing more playful and the longer more directional. It will be interesting to compare those on snow.

Sounds like a solid comparison The difference in DNA between the 172 cm and 180 cm Nosi is pretty clear. The shorter one definitely seems more playful, while the longer one will likely feel more stable and directional. Can’t wait to hear how they perform on snow

(I too am a 42-43 EU so this is particularly helpful!)

OK! So- even when you are at +1.5 from BP it is still a few cm back from the boot center mark? WOW!

Question- as a downhill focused ski- what would stop you from mounting at boot center?

I am curious as to where boot center is on the effective edge of that ski...

[lilcliffy]

To continue: The 172 cm Nosi looks proportionally really good and it also skis really well. I have the bindings mounted pin line +1 cm from the bp.

And- consistent with your measurements above- +1cm from BP is still cms back from boot center?
Again- what would stop you from mounting at boot center?

172 cm Nosi’s true tip to tail length is 170 cm and the boot center mark is 75 cm from the tail (= -10 cm from the true center).

And how deep is the shovel rocker?

180 cm Nosi is 178 cm and the boot center mark is 77 cm from the tail (-12 cm true center). There is 6 cm more ski in front of the bindings if they are mounted to the same position compared to the boot center mark and only 2 cm more ski at the back.

A bit confused- are you saying that at boot center there is more proportional shovel length on the 180cm ski vs the 172?

Bp vs boot center mark difference is about the same on both lengths. When the pin line is +1,5 from the bp the measured center of 43 size Svartisen is about -2 cm from boot center mark (180 cm ski).

Oh- ok- this is not as significant as I thought-
Also- considering you are using a 75mm boot- whose pin-line is ~2cm further forward than NNN-BC/XP- wouldn't that put +1.5cm from BP right on boot center with a 43EU NNN-BC/XP boot?

The 180 cm Nosi is about 1,5 mm thicker at boot center mark so it must be atleast somewhat stiffer too.

So visually those two lengths have quite a different dna, the shorter beeing more playful and the longer more directional. It will be interesting to compare those on snow.

Based on what you are measurements and descriptions-
I would personally lean towards mounting at boot center...

How deep (cm) would you say the shovel rocker is? And same question for the tail?

I wonder where boot center falls on the effective edge of the ski...

[stenu]

@lilcliffy here comes the measures:
-172 cm Nosi eff edge 139 cm, bc mark 63 cm from tail (center of eff edge 69,5)
-180 cm Nosi eff edge 147 cm, bc mark 66 cm from tail (center of eff edge 73,5)

Compared to the center of eff edge both bc mark and bp is further back on the 180 cm Nosi:
-The pinline on 172 Nosi with the bindings mounted about bp +1 cm is 5,5 cm in front of the center of the eff edge
-The pinline on 180 Nosi with the bindings mounted about bp +1,5 cm is 4,5 cm in front of the center of the eff edge

The narrowest point of the ski is at bc mark on both lengths, also the highest camber is at bc mark on both lengths. I think it is also important to remember that as I know, the bc mark is ment for AT boots, because this older Nosi was sold as a light AT/ski mountaineering ski. I believe the new version does not have a bc mark at all. I am using the bc mark only for comparing the measures bethween the skis not as starting point for measuring the mounting point.

Yes Nosi is a DH orienteed ski for me. Anyway because I am doing also longish (about 10-15 km/day) traverses to get me to the best downhill spots, I wanted a compromise bethween descending and flat/upphill skiing performance. Therefore a xcd style mounting point that is based on the bp, not the bc mark - but for dh performance moved slightly froward.

Having the bingings mounted too much forward from the bp makes the skis back weighted which is difficult when you need to lift the skis at tight spots and when making uphill kick turns. Moving the bindings forward will also make the ski glide less well with the X-skins. I was also afraid of tip dive in deeper snow downhill skiing (with the shorter Nosi) if I would go too much forward with the mounting point.

That was basically the thinking process when I mounted the bindings to 172 Nosi. They ski like a dream with bp +1 cm and therefore I wouldn’t change nothing with them. The shovel of the 180 cm Nosi is proportionally 2 cm longer (compared to the bc mark and bp) and therefore I decided to mount the bindings to a slightly more forward position but like said I did not want to go too much forward from bp. Maby I could have gone even more forward, time will tell. At this point it’s all speculation

Anyway because there is less tail rocker on the 180 cm Nosi the tails will be less pivoty or ”smeary” than 172 Nosi’s tails undepending of the binding position.

Here is a tip rocker photo, both lengths are about similar. There is a photo of both lengths’ tail rocker on the previous page.
