Cross-Check is a though-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.
