The longer the ride, the more important your bike's fit becomes. With superior fit as a design goal, Diamondback's Airen endurance road bikes have long been a hit with women, and with the introduction of new carbon framesets they've become even better. Using the same construction methods as DB's race bikes, the Airens are hand built to be the smoothest women's bikes you'll find. Finger-thin carbon seat stays keep the bike's ride supple, while thru-axles front and rear aid in stability and tracking. Hydraulic disc brakes give new levels of control and confidence in all conditions, letting you enjoy your ride even more. Touches like our Closed Circuit Cable Routing and graceful lines only add to the appeal of the silky smooth Airen 4.
