When it comes to gravel bikes, the developers at Surly just want to throw a few bananas in their bags and see where the road takes them. They choose different surfaces on their rides, often transitioning from asphalt to gravel and even unpaved roads. With the Midnight Special, you can comfortably tackle all of that.
