I'm looking to buy a good entry level bike, mostly to use for commuting but looking to do exercise on it now and then (typically a runner but like to get on the bike!). I've found two bikes on bikes direct for $400, the mercier galaxy road bike and the motobecane mirage sport. The mercier is Reynolds 520DB Cro-Moly steel and the motobecane is aluminum. Just looking for some opinions on which would be the better option? (Can't really spend more then $400)
