Description
Utilising the same, top-shelf OMX monocoque carbon frameset as the highest-end models in the lineup, the Orbea Orca Aero M20LTD Disc Road Bike delivers unrivalled power transfer and sublime aero performance. Stiff and lightweight, the frame features an aggressive geometry and impeccable handling at all speeds, with its short wheelbase and chainstay offering a responsive and engaged feel on the tarmac. A traditional bar and stem allow for a wide range of adjustments, prioritising ergonomics to improve rider comfort and control.
A proven choice for road performance, the Shimano Ultegra 11-speed drivetrain balances a low weight with longevity, making it an ideal choice for smashing out weekend mileage. This bike also features Shimano hydraulic disc brakes, which see epic stopping power to boost confidence on steep gradients and in poor weather. The Fulcrum Racing 400 DB wheelset is fast-rolling and quick to accelerate, with its aluminium rim delivering lasting, robust performance.
