The Surly Preamble is designed to introduce riders to Surly's pavement and gravel line, highlighting the brand's most essential features: durable custom steel tubing, a renowned ride feel, and 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 the Surly Bridge Club. For new weekend riders and veteran commuters alike, the Preamble makes it easier than ever to get out of the car and onto a tough and comfortable ride. The frame and fork are constructed from 100% Surly Chromoly steel with a double-butted main triangle. Five frame sizes are available to fit nearly every rider (XS, S, M, L, XL), with a slightly sloped top tube on XS and Small frames for improved standover and comfort. The Preamble is friendly with both 1x and 2x drivetrains and features mounts for racks, fenders, and two bottle cages located on the seat tube and down tube. Tire clearance varies by frame size: XS–S frames accommodate 650b x 41mm tires (650b x 38mm with fenders), while M–XL frames fit 700c x 41mm tires (700c x 38mm with fenders).
