I am going to be starting my first season of real racing this year and want to do all sorts of events (have already done some cx this year) road and XC. the road races will mostly be a weekly training crit here in town and several big crits in the district but i don't want to focus on road cuz trails are too much fun and more my style....anyway i am going to get my uscf liscence because of the number of crits will make it worth it, but my question is do you HAVE to get a NORBA liscence too to race XC or are these transferable? i am trying NOT to spend 120 bucks (or ever how much for both) just on liscences. any suggestions or answers?
