The Trek Checkpoint ALR 4 Gen 3 is made for riders who want one bike that can take on anything — from daily commutes and fitness rides to gravel routes and light touring. Its 300 Series Alpha Aluminium frame is strong yet lightweight, with internally routed cables for clean lines and protection from dirt. Trek’s modern endurance geometry delivers a stable, confident ride feel on loose gravel and broken roads while keeping comfort high on long days out.
The frame offers clearance for up to 50 mm tyres, giving you freedom to fine-tune grip and comfort for every surface. Integrated rack, mudguard and frame-bag mounts make it easy to turn the Checkpoint into a capable adventure companion for commuting, bikepacking or weekend escapes.
Up front, the full-carbon fork helps smooth out rough terrain and reduces weight while maintaining precise steering. The Shimano CUES U6030 shifters and U8000 rear mech deliver smooth, reliable 11-speed shifting, paired with a 40-tooth chainring and a wide-range 11-50 t cassette for confident climbing and steady cruising.
Braking is handled by Shimano CUES hydraulic discs, giving controlled stopping power in all weather conditions. Rolling on Bontrager Paradigm 23 Tubeless Ready wheels and Girona Pro 700×42 mm tyres, the Checkpoint balances fast rolling with dependable grip thanks to GR puncture protection and an aramid bead construction.
Every detail is built for real-world riding — from the Blendr-compatible Bontrager Elite stem for easy light or computer setup to the comfortable Verse Short Comp saddle designed for endurance comfort. At around 10.4 kg, it’s light enough for long climbs yet tough enough to handle rough tracks and loaded rides.
Whether you’re discovering local gravel routes, heading out for an all-day adventure or tackling a multi-day trip, the Checkpoint ALR 4 Gen 3 is a confident, capable and endlessly adaptable choice for riders who love to explore.
