Orbea Terra H30 1X Disc Gravel Bike 2021
The Orbea Terra H30 1X Disc Gravel Bike supplies a versatile ride character within an affordable format to award multi-surface performance to a considerable scope of riders. Whether traversing the gravel, hitting the road during winter training or racing in the local cyclocross league, the Terra H30 delivers with aplomb thanks to its comprehensive blend of traits.
The hydroformed aluminium frame has an advanced triple-butted construction to result in a lightweight chassis that is responsive for efficient and nimble climbing but resilient for the harshest of surfaces. The full carbon fork complements by reducing vibrations and by increasing line accuracy thanks to its steering rigidity. Realised with a finely tuned and balanced geometry, the frameset places the rider in a powerful but composed position to facilitate efficiency and comfort across several genres of riding.
Robustness and reactivity are offered via the Blackjack Ready GR wheelset with its strong, wide rim being complemented perfectly by the Vittoria tyres to provide traction and compliance. At the same time, the Shimano 11-speed gears provide a wide range of ratios to tame any terrain before the single chainring bestows reliability even across highly irregular riding surfaces. The hydraulic disc brake configuration completes an extensive spec list for confidence in wet weather or across technical terrain via its accurate and smooth stopping power.
