I have never thought of this, I had a set on my quad and liked them a lot! You may have to get higher riser for them cause they don't have much rise in them, but other than that I don't know why they wouldn't work!
It sounds like a good idea. I have lots of customer's who swear by them, from the hard core AA racers to trail riders everyone has given rave reviews..
They say less arm pump.. Ill have to try a set sometime.
Had them on every sport quad I owned and swear by em. I wouldn't own a sport quad with out them, but never tried them on a sled. Thought about it, but the sled isnt as rough of a ride as a quad so never dropped the $ on them for the sled. I could justify the price for them on my quads, but not so sure for the sled.
I have ran them on more than one bike and multiple race sleds now and have loved the benefits of them. Zbroz Racing is a dealer that has sold them to snow customers and uses them for personal sleds.
