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.
- The IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around
- All-new progressive geometry is quick and nimble yet keeps you stable and in control on fast, choppy descents
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions
- Integrated frame bag mounts and rack and mudguard mounts make it easy to carry gear and water
New progressive geometry
For quick, nimble handling that still keeps you stable and in control on rougher descents.
Tyre clearance
Lots of clearance means you can run meatier tyres (700x45 mm or 27.5x2.1") for tackling chunkier gravel and terrain.
Tons of mounts
Integrated frame bag and mudguard mounts make it easy to carry gear and water.
Sleek internal storage
A built-in storage compartment in the downtube lets you stow tools and gear.
IsoSpeed smooth
The damped, controlled rebound of the IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around.
Shimano GRX
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.
