Surly
Surly makes functional bikes that do what they’re designed to do. These bikes are built to last a long time.
Surly ‘Natch!’ tubesets are 100% proprietary 4130 CroMoly. This means every model has a unique tubeset designed by our engineers to match the intended use and loading characteristics of the bike. In addition, sizes within each model have tubesets scaled to preserve optimum butting profiles. Our forks, too, are proprietary and model-specific. These features create the characteristic “Surly Ride” – comfort and compliance – that is consistent across all Surly bikes. Add to this foundation of proprietary tubing our assortment of custom dropouts, fittings, and castings. The frame is the most important part of the bike. Design details and frame features create a foundation that Surly riders can customize to make it their own.
