So I have $500 or less to spend on a new set of wheels. my bike is a hardtail and currently has v-brakes. If I get a disc specific wheel then I will have to get disk brakes included in th $500 limit. As for use: next year is going to be my first year racing xc. I don't do any drops or free ride stuff. the wheels will need to be strong enough to hold up to almost daily riding. what would you guys recomend?
