Trek Checkpoint ALR 3 3rd Gen Dark Carmine 2027 gravel bike

The Checkpoint ALR 3 3rd Gen Trek is an aluminium gravel bike designed for adventure, bikepacking and long rides on roads and trails.

Its Alpha Series 300 aluminium frame and modern endurance geometry offer an excellent balance between comfort, stability and performance. The full-carbon fork helps to filter out vibrations and bumps on rough terrain.

Its Shimano CUES 10-speed drivetrain with an 11-48 cassette provides a wide range of gear ratios to tackle both fast-paced sections and climbs. The Tektro C550 dual-piston mechanical disc brakes provide reliable and easy-to-use braking on a variety of gravel terrains.

The Bontrager Paradigm 23 Tubeless Ready wheels are fitted with Bontrager Girona Comp tyres in 700x42 mm. The frame accommodates tyres up to 50 mm without mudguards and features numerous mounting points for luggage racks, mudguards and panniers.

With its internal cable routing, thru-axles and versatile design, the Trek Checkpoint ALR 3 is ideal for exploring beyond the tarmac.
