Vélo gravel Trek Checkpoint ALR 4 3e Gen Matte Keswick Green to Lichen Fade 2027

The Checkpoint ALR 4 is an aluminium gravel bike designed for cyclists who want to venture a little further off the beaten track. Its modern endurance geometry and full-carbon fork absorb road bumps, whilst the clearance for tyres up to 50 mm enhances grip and confidence on loose terrain. The Alpha Series 300 aluminium frame, featuring internal cable routing, a UDH dropout and a T47 bottom bracket shell, offers plenty of mounting points for panniers, pannier racks and mudguards, ready to accommodate any adventure setup.

The 11-speed Shimano CUES drivetrain, combined with an 11-50 Linkglide cassette and a single 40-tooth chainring, offers a generous gear range for both climbing and fast riding on the flat. Shimano hydraulic disc brakes ensure precise stopping power in all conditions, whilst the Bontrager Paradigm 23 Tubeless Ready wheels, fitted with Bontrager Girona Comp 700x42 tyres, offer the ideal balance between rolling efficiency and versatility. Bontrager Elite Gravel handlebars and a Verse Short Comp saddle complete this build, designed for both long rides and everyday commuting, in its Matte Keswick Green to Lichen Fade colour scheme.
