hej guys!
i could need some help!i have to do a little presentation about rocker skis and i'm searching for articles and good information about it! not that i don't know about rocker ski..i just need more sources!
and i need some info about the history of rocker!
i remember reading a good article about how shane began with waterskis then the spatula, k2 etc! and how other companies started to work with rocker too but can't find it anymore!
so if anyone got a link to an article, that would be awesome!
