It's right for you if...
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'd rather spend your money on a lightweight carbon frame than a top-of-the-line drivetrain, but you still expect your workhorse gravel bike to perform. You want a bike that's both fast and comfortable, and you want endless carry options for gravel races and everyday adventures.
The tech you get
A 500 Series OCLV Carbon frame with Rear IsoSpeed and rack and fender mounts, a 2x11 Shimano GRX drivetrain with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power, wide 700x40c gravel tires for added stability and traction, and a vibration-absorbing handlebar.
The final word
Light, fast, comfortable. Checkpoint SL 5 is a carbon gravel bike that nails this trifecta. A quality groupset, massive tire clearance, options for carrying gear, an OCLV Carbon frame with IsoSpeed, and a ride quality that can't be matched.

Features
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road. No tubes mean there’s no pinch flats, allowing you to run lower tire pressure. With lower tire pressure you can increase traction, control. and comfort, reduce fatigue on you. Best of all, the tire sealant seals up punctures as soon as they happen!
500 Series OCLV
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.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
