The Diamondback Airen 2 endurance road bike was built for the woman who wants to be comfortable on every ride, whether it’s completing the summer’s big century, joining a local cause ride, or just going for a casual spin with friends. The aluminum frame fits like a custom bike, due to its Enhanced Performance Geometry. EPG allows you to sit a bit more upright than on a race bike, taking some of the strain off your neck and lower back. But don’t let that comfort fool you into thinking this bike is sluggish. It’s outfitted with a full Shimano Ultegra parts group, a responsive carbon fork, and new for this year: disc brakes! With HED wheels and Michelin tires rounding it out, the Airen 2 is a road bike that will serve up mile after mile of sensible performance.
