New Gravel Endurance geometry
A new confident and comfortable Gravel Endurance geometry puts you in a more relaxed upright riding position so you can stay comfortable on even your most epic adventures.
Big ’ol tyre clearance
Roll over the rough stuff with room to fit gravel tyres up to 50 mm wide (as measured).
Bigger in-frame storage
More internal frame storage and a bigger storage door lets you fit all your flat tools inside your bike so you're always ready for whatever the gravel road throws at you.
Mounts galore
The new Checkpoint SL is equipped to carry everything you need with mounts on the frame and fork for front and rear racks, mudguards and Adventure Top Tube, Frame and Triangle Bags. Plus, the new frame has been optimised to fit extra hydration in addition to all your bags.
Suspension fork and dropper post compatible
The Checkpoint SL is now compatible with dropper posts and suspension forks with up to 40 mm of travel so you can send it on chunkier gravel and steeper descents.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style.
See the guideBlendr-compatible stem
Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.

Gravel Specific Tyres
Wider gravel-specific tyres provide better traction and more stability while riding on gravel or dirt tracks.
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.
