Details

Checkpoint ALR 3 is the best value gravel bike in the lineup. Kitted out with a 300 Series Alpha Aluminum frame, Checkpoint ALR 3 is just as responsive on chunky gravel roads as it is smooth on the tarmac. Tubeless-ready wheels help fight punctures in the rough while a 2x9-speed Shimano groupset and mechanical disc brakes balance budget with reliability.
