Diamondback Clarity 1 Women's Bike. The Diamondback Clarity 1 Women's Bike blends the best of the road and mountain worlds to provide a sleek, upright riding bike. Featuring Diamondback's women's specific Devine Designs geometry, the Clarity 1 is perfect for commuting, training and weekend rides, but can really kick up the performance level when so inspired. Its rock solid foundation is a 6061 T6 butted aluminum frame with aero straight blade steel fork which delivers smooth, stable and precise handling. A Shimano 21 speed drivetrain can handle both flat roads and climbs with equal aplomb, plus the 7 speed EF trigger shifters make changing gears a breeze. Roll in comfort all day long perched on a gel saddle and ride with peace of mind knowing the Clarity 1's linear pull brakes deliver some serious stopping power. And for maximum versatility, the 700x32c Kenda Kwick Trax tires provide the means to take in both paved and dirt surfaces when you're out enjoying the great outdoors.
