Orbea Avant H30-D Disc Road Bike 2021
Fusing a state of the art aluminium frame with a comfortable geometry and a smattering of precise components, the Orbea Avant H30-D Disc Road Bike promotes performance to the most enduring rides across mixed topography and varying road surfaces.
A hydroformed frame with neat internal cable routing is realised from a high grade of aluminium and boasts variable thickness tubing to increase lateral stiffness and power transfer while keeping the weight low. The innovative kinked top tube of this frame works by creating a smaller rear triangle to improve vertical compliance and smooth out rougher riding surfaces. Further comfort is promoted by the carbon fork blades that stop road vibrations from reaching the hands and the generous amounts of frameset clearance that permit the use of broader and plusher tyres. An endurance-inspired geometry puts the rider in a comfortable position by reducing the reach and increasing the stack and allows the longest rides to be conquered with lowered levels of fatigue.
Strong but light alloy wheels accelerate quickly but are low-maintenance, and the Shimano 105 gear set up provides a wide range of ratios and is a dependable performer. To complete the build, confidence-inspiring braking in all weather is guaranteed by the hydraulic disc brake configuration.
