The Surly Midnight Special is a real road-plus bike for riders who don't want to rely on perfect tarmac. It feels just as comfortable on rough, cracked road surfaces as it does on long gravel sections. The steel frame absorbs vibrations, smoothes out potholes and ensures a smooth, controlled ride - which is exactly what the Midnight Special was built for.
If you're travelling by road bike, you often just want to grab a few snacks and see where the road takes you. And that road is rarely just smooth tarmac. The Midnight Special loves varied surfaces: from good roads to fine gravel to really bad surfaces. It is comfortable, stable and surprisingly fast everywhere.
