Venture away from the crowded bike lanes and jump aboard Surly's Midnight Special for a grand adventure on an array of forgotten back roads. The Midnight Special smooths chunky tarmac and bumpy dirt with its vibration-damping Chromoly steel frame and clearance for plump tires, allowing you to chase skyline beyond the city in total comfort.

It utilizes modern road standards like flat-mount disc brakes, 12mm front and rear thru-axles, and a 44mm head tube. Couple all that with a 650b x 60mm or 700c x 42cm tire clearance and you have a bike that will withstand evolving trends and standards. Surly deliberately kept the Midnight Special a little leaner on the braze-on side of things. Well, lean for a Surly. It has mounts for racks, fenders, and three water bottles so you can bring what you need for a long road ride, keep your keister dry, and still pee a healthy clear at the end of your ride.

WARNING: Cycling can be dangerous. Bicycles and bicycle products should be assembled and serviced by a professional mechanic. Never modify your bicycle or accessories.
