Orbea Terra M30 Disc Gravel Bike 2021
Infusing enthusiasm and confidence into any rider, the Orbea Terra M30 Disc Gravel Bike is ready and set to roll across a multitude of surfaces during the biggest of adventures. A comprehensive, gravel inspired design is joined by advanced materials and proficient components to bestow heightened performance, whether venturing into the wilderness or commuting in the darkest of winter months.
An advanced carbon composition is presented within a monocoque construction to provide a lightweight but ultimately responsive frame that is eager to conquer any climb. Sculpted tube sections are conceived and positioned in line with specific requirements to award a blend of lateral stiffness and rough surface comfort. Realised with a size-specific geometry, the frame supplies composed handling traits for the most technical of riding scenarios to any rider of any height.
The Blackjack Ready GR wheelset has a robust alloy rim that is also light enough to promote an enlivened ride experience. The 21mm internal width of this rim mates perfectly with the Vittoria tyres to supply cushioning, traction and low rolling resistance. A Shimano 11-speed, double chainring gear configuration ensures that any topography can be conquered in an unflappable fashion thanks to the broad scope of ratios provided. At the same time, the hydraulic disc brakes donate confidence via their modulated and powerful stopping power that isn’t affected by even the worst of weather conditions.
