The Checkpoint SL 5 AXS Gen 3 is an adventure-ready carbon gravel bike built to roll into the distant horizon. Its lightweight carbon frame is designed with comfort-focused geometry, room for beefy 50 mm tyres (as measured), and plenty of frame and fork mounts.

It comes equipped with a wireless SRAM Apex XPLR AXS drivetrain to deliver plenty of gears for exploring the dusty road. IsoSpeed comfort tech
IsoSpeed comfort tech smooths pot holes and fatiguing bumps in the road so you can ride stronger for 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 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. We recommend clipless road pedals for control and efficiency.
