More options
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 drive train, but you still expect your workhorse gravel bike to perform. You want a bike that's both fast and comfortable, and you want endless carrying options for gravel races and everyday adventures.
The tech you get
A 500 Series OCLV Carbon frame with Rear IsoSpeed, powerful flat-mount hydraulic disc brakes, a full 2x11 Shimano 105 group set and 700x40 Bontrager GR1 Team Issue Tubeless Ready gravel tyres. Checkpoint SL 5 also has Control Freak internal cable routing, a Bontrager Elite IsoZone handlebar with foam pads integrated into the tops and drops, 12 mm thru axles, mudguard and rack mounts, and Stranglehold dropouts.
The final word
Light, fast, comfortable. Checkpoint SL 5 is a carbon gravel bike that nails this trifecta. A quality group set, massive tyre clearance, options for carrying gear, an OCLV Carbon frame with IsoSpeed and a ride quality that can't be matched.

IsoSpeed decoupler
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.

Flat Mount disc brakes
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.
Ride Tuned seatmast
Our no-cut Ride Tuned seatmast is designed for the rigours of pro racing. It's the lightest, most comfortable solution for day-in, day-out performance and comfort, however rough the roads or hard the riding.
Carbon Armor
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.
Stranglehold dropout
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.

Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tyre pressure for increased traction and comfort without the threat of pinch flats.
Blendr-compatible stem
Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
