The Checkpoint ALR 4 is a high-value gravel bike ready for the roads less travelled. Kitted out with a 300 Series Alpha Aluminium frame, the Checkpoint ALR 4 is just as responsive on chunky gravel roads as it is smooth on the tarmac. Tons of features like tubeless-ready wheels, a SRAM Apex 11-speed drivetrain and mechanical disc brakes make Checkpoint ALR 4 the perfect ride for ease of entry into the wide world of gravel.Does Not Come With Bags
