The Checkpoint SL 5 is a carbon gravel bike made for epic adventures. It's built with lightweight OCLV Carbon, a 2x12 Shimano GRX drivetrain, terrain-smoothing damped 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 and have a great time. You want a bike that's both fast and comfortable, and you want endless options for loading up gear and heading to gravel races and on everyday adventures.
A 500 Series OCLV Carbon frame with damped rear IsoSpeed and carbon armour, progressive geometry that's stable at speed and efficient when you're grinding up a climb, internal frame storage, hidden cables that won't interfere with bags and integrated frame, fork, rack and mudguard mounts. Plus, a carbon fork, a 2x12 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.
For quick, nimble handling that still keeps you stable and in control on rougher descents.
Lots of clearance means you can run meatier tyres (700x45 mm or 27.5x2.1") for tackling chunkier gravel and terrain.
Integrated frame bag and mudguard mounts make it easy to carry gear and water
A built-in storage compartment in the downtube lets you stow tools and gear.
The damped, controlled rebound of the IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around.
Shimano GRX was designed from the ground up for gravel adventure. With its gravel-specific ergonomics, optimised gearing options, rugged reliability and quiet, stable drivetrain, GRX sets itself apart from the rest of the component world.
