Orbea Terra H40 Disc Gravel Bike 2021
The Orbea Terra H40 Disc Gravel Bike offers a versatile performance across a multitude of surfaces and promotes this to a vast spectrum of riders thanks to its affordable price point. Feeling completely at home on gravel, dirt or road, the Terra H40 makes for a trusty companion when exploring the wilderness, racing in the local cyclocross league or when winter training.
The aluminium frame is hydroformed and triple-butted to save weight and increase strength and grants a reactive ride that is infused with natural rough surface resilience. The partnering carbon fork eliminates vibrations while also increasing steering accuracy for technical riding scenarios. Realised with a balanced geometry, the frameset places the rider in a powerful and efficient position that is also comfortable to facilitate long hours in the saddle.
A robust Blackjack Ready GR wheelset tackles irregular and rutted paths with consummate ease while also being lively enough to permit surging accelerations. The partnering Vittoria tyres complement by affording grip, cushioning and low rolling resistance across a gamut of terrain.
The reliable 10-speed Shimano gears and double chainring collaboration allow the rider to tackle any landscape with aplomb before the hydraulic disc brake configuration completes thoroughly by bestowing accurate and reliable stopping power, no matter the conditions.
