The last 10 years i've ridden nothing but mountain bikes. I want to get a road bike to improve my stamina and frankly the trails are getting too crowded too have fun on. I know a bit about selecting a Mountain Bike as i have a Specialized Dual Suspension XC bike w/Aluminum Frame but i know NOTHING about Road Bikes. I'm not going to Race but i want something that won't hold me back. I want to spend around 4-500 for a bike - which for a mountain bike won't get you much. Can anyone make any recomendations on what too look for in this price range and is it too low to get a quality bike - remember, i'm not looking to enter the Tour De France.
