  • A better way to produce aluminum

    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.

Overview

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.
