Founded in 1998, Bloomington, Minnesota, United States Surly Bikes are popular for their steel frames, hand-crafted in Taiwan from Chromoly steel tubing, and carefully welded to produce some of the most durable bicycles on Earth.
Rather than lightweight racing bikes or technical mountain bikes, Surly produces tough, purely steel-framed adventure bikes for long-distance touring, bikepacking, and fat biking.
Each style and size of the bike is designed individually to ensure the frame has all the correct lengths, angles, and stiffness for the bikes’ intended use.

Surly Pavement bikes
Straggler / Midnight Special / Cross-Check / Steamroller (Frame only, reviewed at the bottom of the article)
Pavement and gravel bike
The Straggler is a beast of a gravel bike that can be adapted for several uses, including commuting, cyclocross, and light touring. Ideally, this bike will get you to work in the week and out into the countryside on weekends. The frame has forward-exiting horizontal dropouts for fixie or single speed setups and fits 650b or 700c tires up to 41mm width with fenders.
With front and rear mounts for lightweight racks and comfortable Salsa drop bars, it suits weekend bikepacking excursions or credit card touring. SRAM Apex sorts out the 1×11 gearing, with Alex Adventurer and Surly Knard fitting out the wheels.

If your work commute involves tarmac, cobblestones, and rocky trails then this is the bike for you.
