Checkpoint ALR 5 XS Fjord Blue to Miami Green Fade

Checkpoint ALR 5 is an aluminum gravel bike built for venturing anywhere. It pairs modern endurance geometry with a carbon fork for road-smoothing comfort, while 50mm of tire clearance gives you room for tons of grip. It comes equipped with SRAM Apex XPLR 12-speed shifting, hydraulic disc brakes, Tubeless Ready Bontrager Paradigm wheels, and tons of mounts for bags and gear.

• Checkpoint ALR features the same updated endurance geometry as its carbon sibling, giving you comfort and control in the rough stuff
• You get road-smoothing comfort from a full carbon fork and clearance for up to 50mm tires
• Its spec'd with 12-speed SRAM Apex XPRL shifting that's extra durable and provides plenty of gears for steep climbs and long grinds alike
• Tons of mounts on the frame and fork give you places to load up for epic bikepacking adventures or commuting around town

Mounts galore

The new Checkpoint ALR 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.

A better way to produce aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
