Comments:
Road Bikes: They are lighter and designed for speed and performance, comfort is less important. For racing, touring and long rides on bike paths and roads. Narrow wheels and tires are fragile and require more maintenance.
6 speed: easy to use and perfect for the city and bike paths. There are enough ratios to gradually build speed without forcing too much. Not great for steep hills, ok for medium grade climbs. - Derailleur: Shimano 600 SIS
Tires 700 x 23c: very narrow tires, slick, for racing on asphalt.
