I've been a recreational mountain biker for a couple years, using a Specialized Rock Hopper. Due to certain circumstances, I will be needing to purchase a road for my main mode of transportation. I've been planning to purchase one for some time and get involved with with competitive races. This presents a good opportunity to do so. Point being, I NEED A BIKE FOR COMMUTING IN COLD MICHIGAN WINTERS, AS WELL AS RACING UNDER NORMAL CONDITIONS. I'm looking to spend between $900 - $ 1500. Any input on what I should look at would be greatly appreciated. Thanks.
