I'd love to be sponsored. In all honestly, yes I'd like free/discounted parts. But the main reason I'd love to be sponsored, is just the thought. Someone/thing reconising you as a good sport, you arent a general cock to the public to the public, telling them to get f**ked if your on their wall etc. It'd just boost my confidence and dedication to the sport.
I'm 15, I'm skint and my parents don't like forking money out on me. All of my bike, is what I have worked for, not what my parents have got me.
Work your way to the top, like Mark said, dont ask what parts your could get, but ask yourself what you can offer to the company. Be polite with the public, if they ask about the bike, point them in the right way, tell them about it, where it's from etc.
And like said before, making a topic like this, saying how your 14, skint etc won't make companies sympathetic for you. It will just drive them away, as all it seems is you are leeching off them, not doing anything for them.
