Checkpoint ALR 4 is the best value gravel bike in the lineup. Kitted out with a 300 Series Alpha Aluminum frame, 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.

Features

• For quick, nimble handling that still keeps you stable and in control on rougher descents.
• Lots of clearance means you can run meatier tires (700x45mm or 27.5x2.1") for tackling chunkier gravel and terrain.
• Integrated frame bag and fender mounts make it easy to carry gear and water.
