I currently own a Trek 4300 MTB bike. Yes, I know its quite the entry level bike, but its not bad. I'm really into trail riding and I plan on getting into xc racing a little. My two thoughts are should I just upgrade all the components on my 4300 (front shock, disc brakes, etc) to a pro bike level or should I just spring for a new higher end hardtail?
Will I see better performance out of a higher end frame (trek 8500) or is the performance in all of the nicer components??
Thanks for any help!
