Orbea Avant H50 Road Bike 2021
Possessing a multifaceted character, an advanced frame construction and dependable components, the Orbea Avant H50 Road Bike is the ideal companion for the longest of rides whether they be in the mountains or across uncharted country roads.
The high grade of aluminium that makes the frame has a hydroformed, variable thickness construction to raise its stiffness to weight ratio markedly. This frame introduces comfort to the rear of the bike via its kinked top tube design that shrinks the rear triangle to promote increased vertical compliance. In addition, the carbon fork legs smooth road surface irregularities to lower fatigue in the rider’s shoulders, neck and arms.
Hidden cable routing gives a truly clean and professional vibe while the endurance-inspired geometry positions the rider in a slightly more upright position to reduce tiredness in the back muscles during the biggest days in the saddle. Lightweight aluminium wheels are reactive but robust and are driven forwards by the reliable and accurate Shimano Sora gear configuration.
- A super-durable, versatile and enlivening road bike that is great for endurance riding across a variety of road surfaces
- Hydroformed aluminium frame with smooth welds boasts variable thickness tubing to increase lateral stiffness but keep the weight low
- Innovative kinked top tube design creates a smaller rear frame triangle for increased compliance and comfort
- The carbon fork with alloy steerer is torsionally stiff, strong and reduces road vibrations
- Hidden cable routing through the frame grants a crisp aesthetic
- Endurance inspired geometry reduces the reach and increases the stack for a more upright and comfortable riding position
- Orbea R1800 wheels have an alloy rim, are light and strong
- Shimano Sora 9-speed gears are precise and reliable
