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.
The team at Surly are careful to ensure frames are not only of good build quality but also provide a comfortable and efficient ride. They ensure every bike is not only durable and versatile but also affordable – which is made possible with Chromoly steel.
- 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.

The Midnight Special is Surly’s closest answer to a road bike, although it won’t likely be competing in the Tour de France anytime soon. It has clearance for a range of tires from 650b x 60mm to 700c x 42mm and a frame design that looks more suited to gravel paths than the velodrome. If your work commute involves tarmac, cobblestones, and rocky trails then this is the bike for you.
It also features some impressive road-worthy components like TRP flat-mount disc brakes, Salsa Cowbell drop bars, SRAM Rival 1x groupset with 40T crank, and Alex Adventurer tubeless-ready rims.
