Can anyone who is active in the race scene explain the standard classifications for downhill racing? I will be getting a Giant STP 2 fairly soon and I'd like to know which class(es) I could be competitive in a year or two down the road. I love downhill, but I won't be getting an FS bike for it. If there's no way I could be competitive in downhill on a hardtail, can someone recommend a racing type for me?
Thanks and sorry about the beginner questions.
