Any big dudes in here that race XC? What size bike/frame do you ride and what's your setup. I am 6'5" and 220 and will be riding a stretched out S works hardtail. Am i likely to see people over 200lbs and are over 6 ft? Any serious "BIG DUDE" competitors that race alot?
It depends on your class. I am a new racer so I was riding in sport class at the beginning of the series I race in (life got in the way and I only made 5 races :\). I could have raced the Clydesdale class though if I wanted. You'll definitely see bigger guys though, maybe not a ton, but they will be out there.
I'm 6'3 225lbs and ride an XL Specialized Epic. I had a fit done by my LBS and we swapped stems (I think I'm running a 100mm now) and the bike is as comfortable as can be.
