Product Info

Checkpoint SL 7 AXS Gen 3 is a carbon gravel bike built to explore the beyond. Its lightweight carbon frame is designed with a Gravel Endurance geometry, tons of mounts, and clearance for up to 50mm tires (as measured). Plus, IsoSpeed comfort tech helps soak up jarring vibrations so you can float over chatter and potholes. It's decked out with upgrades where you want them most, like carbon wheels and seat post, and a wireless SRAM Force AXS XPLR E1 drivetrain.


IsoSpeed comfort tech

    IsoSpeed comfort tech smooths potholes and fatiguing bumps in the road so you can ride stronger longer.


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 tire clearance

    Roll over the rough stuff with room to fit gravel tires up to 50mm 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, 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.


New gravel bike sizing

    We updated out sizing system to fit an even wider range of riders while consolidating the number of sizes and reducing overlap to make it easier to find the right size for you.
