Surly Cross Check FrameSet

The Cross-Check was the third frame we ever offered. There is no such thing as one bike that can do it all, but the Cross-Check does a good job of most things people use bikes for. It's a cyclocroSingle Speed track bike by design but that's not how most people use it. It does as good a job getting you across the country as it does getting you across town. It's at home on the road and on trails, on gravel, and just about whatever else you might run into. It'll take pretty big tires, or smaller ones if you like. It can be built as a geared bike, a singlespeed or a fixed-gear.

The frame is designed to supply a comfortable but lively ride. The tubing is CroMoly steel, high quality drawn tubing built to our specifications. It's built to work with components of popular sizes, meaning you can find options in tons of new and old parts. It will accommodate a wide range of crank types and chainring sizes. It's got accommodations for racks and fenders front and rear. Because it takes those big tires, so you can outfit it to suit where and how you'll use it.

We offer the Cross-Check as a frameset and also in complete bike form. In fact, we've got two versions of the Cross-Check complete. One is a 2x9, with drop bars, cantilever brakes and traditional bar-end shifters. The other is a singlespeed, geared 42/17, with a Salsa Motoace riser bar, Avid V-brakes and comfy, capable 42mm Continental Tour RIDE tires. Both use the same frame so you can change it up later if you want. There's a reason we still offer the Cross-Check after all these years. The frame is comfy, tough as nails and super versatile. We continue to hear from people for whom the Cross-Check has long been their default go-to bike simply because it performs so astonishingly well.
