The Cross-Check is one of the most iconic bikes in all of 'alt-cycling.' The Surly Cross-Check is one of the simplest, cleanest, and most durable bikes you can find and it's hard to imagine anything more versatile! There's a reason most bike mechanics have owned one at some time or another. Not only does the Cross-Check lend itself to being a parts bin bike, a workhorse, or a true show-pony, but it actually rides awesome - believe the hype! Clearance for 42mm tires all day and compatibility with both 130mm and 135mm QR rear wheels (as well as all the mounts you could ever want for touring, commuting, or courier work,) make it easy to build and with both a 68mm BSA threaded bb and a 1-1\8" straight steerer, it's a simple, tried, and true assembly! **Cross-Check is now a discontinued model so what we've got is what we've got. There will be no more coming back into stock!**
