Bikes. Parts. Chaos.

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

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
  • 4/5 with Tire Clearance
  • 3/5 with Pavement Touring
  • 4/5 with Gravel/Double Track

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