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.

  • You get serious versatility that's suited for a wide variety of ride styles, from gravel and bikepacking to daily commutes
  • Massive tire clearance means you can use tires up to 45c for extra traction and stability in any conditions

  • Powerful mechanical disc brakes make stopping in all conditions easy
