The Trek Checkpoint ALR 3 is a great value gravel bike. Kitted out with a 300 Series Alpha Aluminium frame, the 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 group set and mechanical disc brakes balance budget with reliability.
