Surly Preamble Flat Bar Gravel Bike


Designed to introduce unfamiliar riders to Surly’s pavement and gravel line, Preamble highlights Surly’s most essential features: Durable custom steel tubing, a renowned ride feel, and just the right mounts for running racks, fenders, and bottle cages. Available in flat-bar and drop-bar configurations, it’s disc-brake specific and shares a single-position vertical dropout with Surly Bridge Club. For new weekend riders and veteran commuters, Preamble makes it easier than ever to get out of the car and on top of tough and comfortable Chromoly steel.
