Trek Checkpoint ALR. Gravel-Ready. Adventure-Proven.

The Trek Checkpoint ALR is our pick for riders who want to go further, on more terrain, without the carbon price tag. Built around Trek's 300 Series Alpha Aluminium frame and paired with a full carbon fork, it delivers a ride quality that punches well above its weight. It is responsive on tarmac, capable on gravel, and ready for whatever you throw at it.

Now in its third generation, the Checkpoint ALR gets Trek's Gravel Endurance Geometry: a higher stack and shorter reach that puts you in a more upright, comfortable position for long days in the saddle. Whether you're exploring dirt roads close to home or loading up for a multi-day bikepacking trip, this bike was built for it.
