I am 63 years old and ride a Conndale Quick 5 for my daily commuter. I like the flat bars and the smooth ride of the bike. I use 700C 28 gator back tires which work great on the rough pavement I have on my daily commute to work. On the weekends and for group rides I ride a Scott CR1 team. I am running the 700C 25 Conteneental 4 season tires which have given great mileage with no flats so far.
