I bought my first 29"er for my b-day back in '08...and eventually sold off all smaller wheel sizes (own a paitr of Vassago mtn bikes,700c CX bike...and a pair of 20"er folders). I'm 5'9" and 160 lbs give or take a crap.

Just cause I love em and they work for my riding style/habits/area doesn't mean they will for anyone else...ride what feels best to you
