Preamble Frameset – Best Buds Green Nothing More is Needed. Nothing Less Will Do. The goal was simple: build a serious steel bike with only the features that truly matter. The result is the Surly Preamble — quick and comfortable on pavement, confident and compliant on rough, broken surfaces. You don’t need to cut corners to create an affordable steel bike; you just need to keep things simple. The Preamble can run racks and fenders and carry multiple bottles or bags. Smooth and efficient on asphalt, its double-butted main triangle delivers Surly’s signature steel ride feel while standing up to daily abuse and potholes. Customize it your way: flat bars, drop bars, commuter setup, basket bike, or gravel rig. On the road to steel euphoria, this is the gateway drug.
