Surly Cross Check Black Durable High-Performance Cyclocross Bike Frame

The Surly Cross Check is engineered to bridge the gap between rugged off-road exploration and smooth urban commuting, offering a bike that’s as practical as it is capable. Built from Surly’s signature 4130 chromoly steel with double-butted main tubes for a balance of strength and compliance, this versatile machine handles everything from gravel paths to city streets with ease. Its 1-1/8″ threadless chromoly fork ensures stability on uneven terrain while maintaining a responsive ride feel.

Designed for adaptability, the Cross Check accommodates single-, double-, and triple-chainring setups whether you’re running a geared drivetrain or preferring singlespeed simplicity. The semi-horizontal dropouts allow precise wheelbase adjustments to fine-tune handling, while 132.5mm rear spacing seamlessly integrates mountain or road hubs—no adapters needed. With clearance for 700c x 45mm tires (or 40mm with fenders), it’s ready for adventure on rough trails or year-round commuting through inclement weather.

Practicality meets durability here: an ED-coated frame resists corrosion for long-term reliability, while cantilever/linear-pull brake bosses and fully threaded fork eyelets support racks and fenders effortlessly. Dual water bottle mounts keep you fueled on long rides, whether you’re tackling weekend gravel routes or daily commutes with panniers. The included Surly brake hanger and dropout adjustment screws add peace of mind for maintenance and customization.

Who’s it for?
– Urban commuters seeking a bike that handles potholes and doubles as weekend adventure gear
– Gravel enthusiasts craving wide tire clearance without sacrificing road manners
– Touring cyclists needing robust rack mounts and all-weather capability
