Further enhancing its capability, the bike is compatible with dropper posts and even a suspension fork, allowing for significant future upgrades. With complete builds starting at $1,500 and a frameset available for $1,050, the Checkpoint ALR Gen 3 offers an accessible entry point to a world of off-road adventure.
