Orbea Orca M40 Disc Road Bike 2021
The Orbea Orca M40 Disc Road Bike blends a refined carbon construction, lively character and reliable components to lend a multifaceted and fast performance to a gamut of road rides whether they be in the mountains, across the roughest of roads or through the quickest of valleys.
An optimised layup pattern and meticulous fibre orientation are used when constructing the full carbon frame. This state of the art, lightweight construction infuses high degrees of reactivity and plush levels of compliance for speed up the climbs and comfort across the cobbles. The laterally stiff carbon fork increases steering accuracy and manages surface vibrations while entirely internal cable routing from stem to frame gives a clean and precise vibe. 35mm tyre clearance permits the use of broader, lower rolling and plusher rubber while the race-inspired geometry places the rider in a powerful position and bestows reactive but composed handling characteristics.
Hydraulic disc brakes stop powerfully and precisely in all weather conditions, even when flying down steep mountain passes. At the same time, the Shimano Tiagra gear configuration is dependable, low maintenance and changes accurately every time of asking. Robust but lightweight wheels crown the build by accelerating sharply and by being low-maintenance, even after long rides over the most broken and irregular of surfaces.
