Trek Checkpoint SL5 - 2023-24, 54 cm

2023–24 Trek Checkpoint SL5, Size 54 — Carbon Gravel Bike (Low Miles)

The Trek Checkpoint SL5 is a versatile, fast, and comfortable carbon gravel bike built for everything from long mixed-surface rides to bikepacking and endurance adventures. With Trek’s lightweight carbon frame and carbon fork, the Checkpoint balances efficiency on pavement with confidence and stability on dirt, gravel, and rough roads.

This bike is equipped with a reliable Shimano GRX 2x11 drivetrain, using 48/32 chainrings and an 11–34 cassette, giving you a wide gear range that’s ideal for climbing, loaded riding, and maintaining speed on flats. Shimano GRX hydraulic disc brakes deliver excellent modulation and braking power in all weather conditions, which is exactly what you want on gravel.

Rolling on Bontrager Paradigm wheels with Panaracer GravelKing 43C tires, the bike offers a smooth, planted ride with plenty of traction and comfort. The Bontrager carbon seatpost, Elite 420mm handlebars, and 80mm stem create a balanced, endurance-focused fit that still feels responsive when you push the pace.

This is a Size 54, best suited for riders approximately 5’7” to 5’11”, with only ~500 miles on it. The bike is pre-owned in good shape, mechanically sound, and 100% ready to ride.

Why we love it

We love the Checkpoint SL5 because it’s one of the most well-rounded gravel bikes out there—it’s fast enough to keep up on road rides, comfortable enough for long endurance days, and tough enough for real gravel and dirt. The GRX 2x drivetrain makes it incredibly versatile, the carbon frame keeps it light and smooth, and the low mileage means it still feels fresh. It’s a true “do-it-all” gravel bike that works just as well for exploration as it does for structured training or events.
