Orbea Orca M20LTD Disc Road Bike 2021
Seamlessly linking the highest grade of carbon materials, sophisticated design and accurate components, the Orbea Orca M20LTD Disc Road Bike is a truly versatile, all-out racing machine that delivers speed across any road parcours.
The frame and forks make use of Orbea’s highest grade of carbon fibre, and this is laid via a Dynamic-Structure pattern across the tube sections to deliver incredible lateral stiffness as well as comfort within a lightweight form. The frame's down tube, seat tube and seat stays are aerodynamically tweaked to reduce drag by 10% and the Freeflow fork design aids in this regard by spreading its legs away from the front wheel to reduce air turbulence markedly.
A race-inspired geometry places the rider in a powerful position and also donates nimble but composed handling. The racy attitude is continued by the cable routing that runs through the stem and into the frame to give a professional aesthetic while a frameset-to-tyre clearance of 32mm permits the use of broader, more comfortable and faster-rolling rubber.
Vision 40 SC wheels complement the reactive frameset perfectly via their aerodynamic and lightweight full carbon rims. The wheels are driven forwards by the super-accurate and reliable Shimano Ultegra 11-speed gear system and are stopped in any weather conditions by the powerful hydraulic disc brake configuration, also from the Ultegra marque.
The build is crowned by Orbea carbon handlebars that are light, stiff and comfortable in the hands and a matching carbon seatpost that allows an adjustable amount of set back to help the rider achieve their perfect riding position.
