Checkpoint ALR 4
Trek
Gravel
Checkpoint ALR 4 is an alloy gravel road bike (2025), by Trek, from the Checkpoint lineup. It suits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, while being ready for gravel routes as well as pavement. The main strengths in the metrics are strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and all-round climbing capability rather than a narrow specialty. That said, relative to category specialists, the trade-off is less emphasis on outright speed than speed-focused builds. Add this bike to compare on MatchBikes.com and see how it stacks up against similar gravel models.
