The Surly Preamble Flat Bar is a steel-framed marvel that defies the notion that quality and affordability can’t coexist. Designed for smooth asphalt but also capable when the roads aren’t so smooth, its double-butted main triangle provides a resilient core for enduring life’s rough patches.


Overview

The Surly Preamble is designed to introduce riders to the joy of pavement and gravel riding. Built from Surly’s durable custom steel tubing, it offers the smooth ride feel the brand is known for, with just the right mounts for racks, fenders, and bottle cages to handle all kinds of adventures.

This bike comes in both flat-bar and drop-bar configurations, with a disc-brake-specific setup and a single-position vertical dropout shared with the Surly Bridge Club. Whether you’re new to weekend riding or a seasoned commuter, the Preamble makes it easy to ditch the car and get rolling on the dependable, comfortable Chromoly steel frame.
