they exist.....yet monos are all you see and used for racing.....why? double the surface area has to mean way more speed. Really the only reason sit skis are so much slower is because its just one plank.
 
dual requires a complicated (aka expensive) mechanism to turn (though I have seen them), and I would assume that otherwise they would be more difficult to turn. Semi related, one time I saw a guy shredding on a sit ski at Sugarbush, had a volkl race tiger mounted on it.
 
There are a few makers of "Dual-Skis". That being said, surface area is independant of friction. In other words a Dual-Ski is not faster than a Mono-Ski. There is also the older and most frequenty used "Bi-Ski". Bi-Ski rigs use a speicial ski that can only be used with the Bi-Ski sled. Some folks have mounted Bi-Ski bindings to "regular" skis and used a Bi-Ski rig in that way. Dual-Skis rigs and Mono-Ski rigs can run with any ski one wants as they use a "regular" ski binding. Most of the time those bindings are modified to not allow for release. Since there is no leg to break it is better for them to not release. Also if one is an independant sit-skier they don't want to drop a ski as it would be very hard for them to retreive the dropped ski.

lots of good info there, but in skiing and snowboarding, i was under the impression that yes, more surface area touching the snow generally meant more speed..?

and as the first reply said, yeah that sounds expensive, and without independent control of each ski i dont think it sounds super advantageous. i dont know too much about sit skiers though, beyond that theyre badass as hell
 
Studies have shown that length, or size does not really matter if the preparation is the same. It's more a factor of weight and aerodynamics.

As for the cost of sit ski rigs, yes they are very spendy indeed. From around $3,500 to $6,500. The Bi-Ski rigs have no suspension, so they are the cheapest. Most expensive are the Dual-Ski rigs.

Most people who need a sit ski strive to learn a Mono-Ski. They might start out learning on a Bi-Ski, then progress to the Mono. Witch rig is best for an individual may also depend on their level of disability.
 
wow really? but wouldnt two dudes with exact size/weight, but one on little skis and the other on bigger skis, go different speeds?

thanks for the info on sitskis. so much respect for those dudes
 
BAM. The bi ski is the entry level to the world of sit-skis. Mono skis also turn VERY easily. Like, turn your head and it will initiate a turn easy. Sometimes people with mobility limiting diseases have too much movement for a mono. For example, my dad is having a very hard time progressing to a mono because he still has a lot (relative to someone that's say.. a paraplegic) of leg movement.
 
I think it becomes more of an issue of stability. Also, I saw the part about how usually the bindings don't release. I was on the chairlift one time with some friends, and we saw a a guy again a mogul with his ski on the other side. My friend waited tell we got closer and almost yelled yard sale, but then he saw the guy was on a sit ski. Someone helped him up, and we saw him go, it was the same guy I talked about earlier, he kills it in the moguls
 


Yes, all thing being equal, the shape of the ski will determine the total

speed. In a straight line, a straight ski will go faster. If one gets really

super short ski he may be a bit slower because of the plow factor. In general a

shorter ski is not slower. Has anybody noticed that "downhill" skis have gotten

much shorter as time has gone by, but speeds have not decreased?
