Surly Preamble Drop Bar Bike Description:

The Preamble Drop Bar Bike is Surly’s take on an affordable, comfortable, and serious do-it-all-bike that has everything riders need and nothing they don’t. Classic steel frame soaks up the bumps while being incredibly durable. The simplicity of a 1X drivetrain, time-proven reliable Avid mechanical disc brakes, and a comfortable upright geometry all contribute to a highly versatile bike for commuting, gravel roads, light touring, and plain ole pavement shenanigans.
