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, fenders, and Adventure Top Tube, Frame, and Triangle Bags. Plus, the new frame was optimized to fit extra hydration in addition to all your bags.

Suspension fork and dropper post compatible

Checkpoint SL is now compatible with dropper posts and suspension forks with up to 40mm 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. We recommend clipless road pedals for control and efficiency.
