Orbea Terra M30 1X Disc Gravel Bike 2021
Promoting performance across a vast spectrum of surfaces, the Orbea Terra M30 1X Disc Gravel Bike infuses enthusiasm and confidence into any rider thanks to a comprehensive amalgamation of advanced materials, a meticulous design and dependable components.
A lightweight monocoque frameset construction realised with a state-of-the-art carbon composition awards a punchy and precise ride experience with which to attack any ascent. Innovative tube profiles are sculpted following specific zonal requirements to bestow both lateral rigidity and serene levels of comfort. At the same time, a size-specific geometry format allows any rider to benefit from a composed but reactive character regardless of their height or riding style.
The sturdy Blackjack Ready GR wheelset traverses the roughest of tracks with consummate ease and is complemented by the multi-surface traction that is awarded by the Vittoria tyres. The Shimano 11-speed gears conquer any landscape thanks to their wide range of ratios while a single chainring set up supplements via low maintenance and irregular surface reliability. To complete, a hydraulic disc brake configuration endows precise and modulated stopping power, regardless of weather conditions or surface technicality.
