Product Information

Trek Checkpoint SL 5 Gravel Bike

If you're looking for a bike that is capable of handling your next bike packing adventure, commute to work or group ride with your family or friends then that is exactly what the Checkpoint is designed for. However, if you're willing to invest in a carbon frame backed by Trek's lifetime guarantee, to speed up your trip, then the SL 5 is the bike for you. Featuring an IsoSpeed decoupler placed at the junction between the seat post and seat tube, which boosts compliance, you will not only find your ride is more comfortable but more enjoyable. The Checkpoint comes with built-in rack and mudguard mounts making carrying all your gear and staying protected from the bad weather easy. Finished off with Shimano's 105, hydraulic flat-mount disc, 11-speed groupset, you can count on smooth-shifting gears that get the balance of value for money and high performance just right. 

Full Specification



Is this bike for you? 

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.


What's involved

A 500 Series OCLV Carbon frame with Rear IsoSpeed, powerful flat-mount hydraulic disc brakes, a full 2x11 Shimano 105 groupset 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.


What to expect

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.
