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.
