When Diamondback teamed with industry experts HED and KQ Studios to design the Serios F, they ended up with revolutionary profiles that produce only half the drag of competitors’ bikes. 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, unparalleled in power transfer and comfort. 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. This bike is part of the new Diamondback Ready Ride Program. Hand built and shipped ride ready in a few easy steps! Diamondback Ready Ride bikes eliminate the usual hassle of tedious at-home bike assembly, an often-ignored process that can take hours. Our program allows you to spend less time assembling your new bike and more time riding it. Ready Ride bikes are hand-built nearly to completion and shipped straight to you. All you need to do is put on the front wheel, seat, and pedals. Yes, the brakes are dialed in and the derailleurs are adjusted: just pump up the tires and go!
