I will be attending University of Kansas this fall and wouldlike to know which bike people think would be best? Mountain, road, hybrid, cyclocross, etc.? It is a hilly campus. However, i need the bike to be light weight b/c I will store it in my dorm room so it doesn't get stolen. Also, i will probably ride it sometimes during the winter and if you've never been to KS, it gets icy during the winter and the hils at KU will be hell! I am 5' 9", 135lbs., 18 y/o. What do you think?
