TREK CHECKOUT: Adventure-Ready Carbon Gravel Bike
Wildly Fun, Freakishly Capable
Introducing the all-new Trek CheckOUT, a full-suspension drop bar gravel bike built for riders who demand versatility and adventure.
From paved roads to gravel trails, singletrack, and even epic bikepacking journeys like the 2,745-mile Tour Divide, the CheckOUT delivers unmatched performance.
Designed to be faster than a mountain bike on roads and more capable than a rigid gravel bike on trails, this bike is engineered for explorers who aren’t afraid to go way, way, way out there.
What’s New
The Trek Checkpoint SL lineup is built for riders who want to go beyond pavement—combining road efficiency with off-road capability. With endurance-focused geometry, carbon construction, and adventure-ready features, it’s designed to handle everything from fast gravel rides to multi-day bikepacking trips.
The addition of internal storage, increased tire clearance, and improved comfort makes the Checkpoint more versatile than ever—equally at home on long-distance rides or rough backroads.

Performance Overview
The Checkpoint SL leans toward comfort and endurance rather than aggressive race geometry. It feels stable on loose terrain, predictable on descents, and efficient on pavement.
IsoSpeed tech takes the edge off rough gravel, making it ideal for long rides where comfort matters just as much as speed. The geometry puts riders in a slightly more upright position, boosting confidence and reducing fatigue.
