Orbea Terra H30 Disc Gravel Bike 2021
The frameset utilises a high grade of aluminium that is hydroformed into a triple-butted construction to provide a light and reactive but also robust chassis. The frame is ready to perform across a multitude of surfaces, from gravel and dirt through to rutted roads and is complemented by the vibration damping properties of the full carbon fork. The balanced geometry of the frameset places the rider in an efficient and powerful position for when the hammer is down but also naturally affords confidence via nimble but composed handling.
The sturdy Blackjack Ready GR wheelset grants rough surface resilience and reliability. This wheelset features a broad internal rim width that combines perfectly with the Vittoria tyres to bestow traction, compliance and low rolling resistance when traversing a variety of surfaces.
A Shimano 11-speed cassette and double chainring configuration provide a vast range of gear ratios with which to attack any landscape, and these are actuated precisely by the Shimano derailleurs. A hydraulic disc brake set-up completes a trusty two-wheeled companion comprehensively by awarding accurate and powerful stopping within even the muckiest of riding conditions.
