I am a runner but I am beginning to feel the effects on my body and want to move to biking. I need some help picking out a bike and have narrowed it down to two bikes. I am 23, 170-175 and 5'11. I want to ride between 400-500 miles a month. If you guys need any more info let me know. I would greatly appreciate your help/advice.
