Vélo gravel Trek Checkpoint ALR 4 3e Gen Living Coral 2027

For those who want to get off the tarmac without compromising, the Checkpoint ALR 4 Trek features a sturdy aluminium frame, combined with a full-carbon fork that filters out road vibrations. Its endurance geometry and generous clearance – accommodating tyres up to 50 mm wide – invite you to explore the most unpredictable trails with confidence. The Alpha Series 300 frame, packed with mountings for panniers, luggage racks and mudguards, transforms just as easily into a bikepacking machine as it does into a companion for daily commutes.

In this Living Coral colourway, the Checkpoint ALR 4 features an 11-speed Shimano CUES drivetrain with an 11-50 LINKGLIDE cassette, designed to tackle climbs effortlessly. Shimano ’s CUES hydraulic disc brakes guarantee consistent braking power whatever the weather, whilst the Bontrager Paradigm 23 wheels in a Tubeless Ready configuration, fitted with Bontrager Girona Comp 700x42 tyres, ensure a ride that’s both fast and reassuring. The Bontrager Elite Gravel groupset, complemented by the Verse Short Comp saddle, rounds off a setup designed for riding far and long, without any nasty surprises.
