Checkpoint ALR 4 is a high-value gravel bike ready for the roads less traveled. 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.
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 27.5×2.1″) for tackling chunkier gravel and terrain.
Integrated frame bag and fender mounts make it easy to carry gear and water.
This bike doesnt come with pedals because youll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style.
