Trek Émonda ALR 5 Disc Road Bike 2021
Trek’s Émonda ALR 5 Disc Road Bike combines an aluminium frame with the same geometry as the pro-level carbon models with reliable, performance-orientated components for a bike which can be used for training rides, tough sportives or weekend exploration. The Ultralight 300 Series Alpha Aluminium frame has Invisible Weld technology to mirror the svelte look of carbon and houses all the cabling internally out of the way of the wind, water and dirt. Added to this is a full carbon monocoque fork for precise steering and better vibration absorption.
Shimano’s third tier 105 groupset is renowned for its fantastic performance and great value for money, offering similarly snappy shifting across the 11-speed cassette as the more premium options. Gearing is perfect for mixed routes, with a nice low gear for hills available. The Bontrager Affinity Disc wheels have a subtle aesthetic and low enough profile not to be troubled by any crosswinds, with the thru-axles adding to power transfer and steering precision.
