Cross-Check is a tough-as-nails, super-versatile road bike that performs astonishingly well on any surface.

Steel Commuter Bike That Can Do it All

There is no such thing as one bike that can do it all, but Cross-Check comes pretty damn close. It's a dyed-in-the-wool commuter and utility rig. It was a "gravel crusher" long before "gravel bikes" existed. Some people have even raced cyclocross on it. Though, we don't necessarily condone that behavior.

Cross-Check was the first complete bike we ever offered. Since then, people have modified them hundreds of different ways to suit their riding styles and preferences. There’s a reason that nearly every person who has ever worked for Surly has owned one.

  • Semi-horizontal dropouts for singlespeed compatibility and wheelbase adjustability
  • Gnot-Rite dropout spacing allows installation of 130 and 135mm hubs
  • Accommodations for front and rear racks and fenders
  • Clearance for 700c x 42mm tires with or without fenders

Bike Capabilities

  • 5/5 with Commuting Commuting: 5 out of 5
  • 4/5 with Tire Clearance Tire Clearance: 4 out of 5
  • 3/5 with Pavement Touring Pavement Touring: 3 out of 5
  • 4/5 with Gravel/Double Track Gravel/Double Track: 4 out of 5

NOTE: You can ride your bike wherever the hell you want, but this is what we think this bike is best at.
