Checkpoint SL Frame Set - Trek Bikes (GB)

Overview

You're in it for the adventure and want a performance gravel bike so you can go further and faster. You spend long days in the saddle, and want the gravel-smoothing ride of Trek's exclusive IsoSpeed decoupler on your dream gravel bike build.

A 500 Series OCLV Carbon frame with Rear IsoSpeed, adjustable horizontal sliding dropouts, a Checkpoint carbon disc fork, fender and rack mounts, and Control Freak internal cable routing. It comes with a headset and is built for 12 mm thru axles, flat-mount disc brakes, and BB90 bottom bracket.

Our highest-end gravel frameset is the ideal starting point for a performance gravel bike build. It's covered in extra mounts that make it easy to carry your gear the way you want, it has an IsoSpeed decoupler for compliance on rough terrain and it includes horizontal sliding dropouts that make it easy to build as a singlespeed.

The IsoSpeed decoupler cuts down on fatiguing bumps in gravel so you can wander more, reach new places and stay stronger for longer
This bike is exceedingly versatile and suited to a wide variety of riding styles, including gravel rides, bikepacking and daily commutes
Extra mounts on the top tube, seat tube and both sides of the down tube make it easy to carry extra gear and water
Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions
Horizontal sliding dropouts make it easy to fine-tune your geometry or build it up as a singlespeed

Features

500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.

The core of Trek's endurance comfort technology is our IsoSpeed decoupler, the result of an 18-month study of how a racing bike performs over rough roads, and how that performance affects the rider. It's a technological revolution.

All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.

A 12mm front thru axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.

Sometimes you need a little extra protection, so we developed our light, tough external Carbon Armor polymer shield. It provides reassurance when you know your down tube is bound to take some abuse.

The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.

The horizontal sliding dropout with redundant securing mechanisms allows for no-slip single-speed or geared options and provides the ability to dial in the geometry to match each rider’s style.

Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
