Hardly an entry TT bike model, the Serios S sports the same advanced carbon frame and fork as its superbike siblings. A mix of carbon fiber weaves allow for the lightest and most responsive frame possible, giving nimble and solid ride characteristics. The straight line speed of this bike is eclipsed only by its ability to corner. Adaptable fit (comfortable for every rider on the Optum pro team—from 5’6” to 6’4”) ensures you’ll be concentrating on your cadence instead of a fatiguing body position. Outfitted with full Shimano 105 components and HED wheels, this is the most affordable Fastest Bike on the Planet. Be confident your bike is up to the task.

Features:
Full carbon Serios frame, a product of wind tunnel and real-world testing
Diamondback Serios Aero Fork, unidirectional carbon for lightweight responsiveness
Able to fit a wide range of body shapes and sizes
Designed in collaboration with KQ Studios, leaders in the aero field
A complete professional quality TT bike for a fraction of the price
