Hi, I am 15, 5'4", and weight 110 lbs. I grew out of my old bike and need a new one. I go mountain biking about once or twice a month and biking on roads a couple times a week, about 10 mi normally (since its my main source of transportation). I guess i need a bike good for both, we were looking at a haro flightline 3 and a gary fisher tarpon. I'm not limited to those, but max price would be $450 ish. Any suggestions..? Thanks in advance!
