the best way I found to get sponsored was to be patient! Get some decent comp results, make some GOOD vids, be a nice person on and off the bike and companys will aproach you, after all no one wants to sponsor a bad rider who is rude and makes a bad image for the brand. if you feel your at a point in riding where a sponsor would be a benefit then get a cv done with all your acheivments and hopes for the future. Ride for fun is the best advice though, everyone things being sponsored is the highest march to acheive in riding, but there are downsides. you may have to run parts you dont like, go to promotions when you are tired, but there are the obvious good points as well. I am currently sponsored by Tartybikes, Ozonys and Trial-tech, but I hope to add to that soon with some sponsors that can cover my travel exspenses
