Hi I found this used Specialized Allez Sport road bike. It was initially selling it for $675, but I negotiated it down to $475. The previous owner doesn't know the exact model and year the bike is from since it was his dad's. I am pretty new to road biking and was wondering if this was a good price for a used bike. Mainly going to be using this bike for commuting and sometimes longer 20-30 miles rides during the weekend. It seems like it has the Shimano 105 drivetrain and it comes with a pair profile design aero bar. Would this bike be able to ride hills and is this bike worth the price or should I just buy a new $1000 road bike? Also if someone can tell the year of the bike, that would be great! Thanks!
