Boing!!!!! Enter the Propulski; “It is a dynamic block that uses the weight of the skier to help him climb.” And all for under 100 grams! Check out their website: http://propulski.free.fr/index.htm . I think this has been highlighted elsewhere in other blogs but hey, why not! Kind of reminds me of the old Saturday Night Live commercials, who knows maybe it works! Any first hand users out there?
Propulski, for all you uphill fiends
