Description
Moulding a sophisticated carbon construction into a highly refined frame silhouette and adding accurate components, the Orbea Orca M20 Disc Road Bike naturally infuses a multifaceted performance that revels in mountain gran fondos, back road excursions and the fastest of chain-gangs.
A high grade of carbon is laid via an intricate format throughout the frame’s tube sections to afford stunning levels of comfort across the roughest of road surfaces and punchy acceleration for climbing and sprinting. This lightweight frame is partnered with a stiff and strong carbon fork that increases comfort and lowers rider fatigue by reducing road vibrations. The already clean aesthetic of the frame is complemented by the internal cable routing that also neatly runs through the stem while the 35mm tyre clearance allows the use of broader, plusher and quicker rolling tyres. A race-inspired geometry crowns the frame by instilling reactivity and poise and also puts the rider in the perfect position from an ergonomic perspective for efficient and durable power transfer.
Light but strong alloy wheels are low maintenance and fast and are driven by the ultra-reliable and precise Shimano Ultegra 11-speed gear configuration. Confidence-inspiring stopping power, even when enduring wet mountain descents is gifted by the full hydraulic disc brakes that are also from the well respected Ultegra stable.
