While Diamondback certainly makes some top end, race specific whips, not all of us prefer that harsh, stiff, stem slammed ride and are instead willing to compromise a bit in the raw speed department to gain a big dose of comfort. The 2016 Diamondback Airen 1 105 Complete Road Bike will get down the road fast while still allowing you to comfortably enjoy the scenery as you traverse a century on rolling coastal pavement or toe the line with friends at a gran fondo.

Its 7005 alloy construction is light with a smooth, responsive, and efficient ride for confident cornering at speeds and stable handling on meandering roads.
