Orbea Avant H40-D Disc Road Bike 2021
A sophisticated aluminium frame is blended with a refined geometry and ultra-reliable components to make the Orbea Avant H40-D Disc Road Bike a perfect choice for the longest road rides, whether they be in the mountains or at a sharp pace across rough surfaces.
The aluminium frame had a hydroformed construction and variable wall thickness to increase its stiffness to weight ratio markedly. Smooth welds link the tubes to give a clean aesthetic, and the kinked top tube design improves comfort by shrinking the rear triangle to increase vertical compliance. The carbon fork blades complement the frame by also possessing high lateral rigidity and by decreasing the effect of vibrations caused by irregular road surfaces. Generous frameset clearance permits the use of up to 35mm wide tyres while the completely internal cable routing gives a sharp, racy look.
An endurance-inspired geometry keeps the rider fresher for longer while durable but svelte alloy wheels give a lively but robust ride experience. Gear changes are looked after by the precise Shimano Tiagra setup and stopping duties are charged to the powerful disc brake configuration that works perfectly in all conditions.
