  • 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 Frameset is the perfect starting point for your dream aluminum gravel bike. Its 300 Series Alpha Aluminum frame features Gravel Endurance geometry to keep you comfortable through long miles, and a full carbon fork keeps things lightweight. Build it up as a bikepacking rig or spec it for your ultimate alloy gravel race bike, the world is your oyster.
