Product Details

The dark art of aerodynamics doesn’t always follow intuition: when Diamondback teamed with industry expertsHED and KQ Studios to design the Serios F, they ended up with revolutionary profiles that produce only half the drag of competitors’ bikes. A champ in the wind tunnel, it’s outside where it excels. In the real world of crosswinds and corners, this bike outperforms all others.

The Serios F frame is a worthy centerpiece. It is constructed with unidirectional carbon to keep it light and efficient. With unique headset spacers, it’s able to fit every body shape: able to keep the entire Optum pro team comfortable, so they can concentrate on going faster than ever before. The geometry is that of a bike that handles: up, down, around hairpins—conditions you’ll actually encounter in a time trial or triathlon. Featuring a full Shimano Ultegra group and HED wheels, it is ready for race day. When every second counts, look to the Serios F to deliver.
