Diamondback's Serios F is champ in the wind tunnel, but it’s outside where it really excels. In the real world of crosswinds and corners, this bike delivers a ride like none other. Unidirectional carbon fiber allows for an ultralight and responsive ride, giving nimble and solid ride characteristics. The straight line speed of this bike is eclipsed only by its ability to corner. An adaptable fit ensures you’ll be concentrating on your cadence instead of a fatiguing body position. Featuring a full Shimano Ultegra Di2 group and HED wheels, it is ready for race day. When every second counts, look to the Serios F to deliver.
