TREK 23 Checkpoint SL 5

Checkpoint SL 5 is a carbon gravel bike made for epic all-road adventures. It's built with lightweight OCLV Carbon, terrain-smoothing IsoSpeed, nimble-yet-stable progressive geometry, internal storage and loads of mounts. All of that adds up to a rad gravel bike capable of crushing the longest, roughest rides and the most ambitious bikepacking trips.

Chamois or cut-off shorts, bikepacking trip or brutal day of gravel racing – you're going to ride far, go fast and have a great time. You want a bike that's both fast and comfortable, and you want endless carrying options for gravel races and everyday adventures.

A 500 Series OCLV Carbon frame with Rear IsoSpeed and carbon armour, a progressive geometry that's stable at speed and efficient when you're grinding up a climb, internal storage, hidden cables that won't interfere with bags, integrated frame bag mounts and rack and mudguard mounts. Plus, a carbon fork, a 2x11 Shimano GRX drivetrain with lower gears for grinding up hills or through rough gravel and Paradigm SL wheels. You can even run a dropper post to get low on long descents.

Light, fast, comfortable. The Checkpoint SL 5 gives you the unmatched ride quality of an OCLV Carbon frame with IsoSpeed and gravel-specific geometry, plus internal storage and a drivetrain built for rough terrain.
