Surly Midnight Special Frameset Description:

The Midnight Special is a road-plus bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement. It excels on pot-holed, deteriorating pavement and the occasional long stretch of gravel. The Midnight Special’s 650b road plus tire compatibility helps it eat up road chatter and absorb all the bumps in the road for a much more comfortable ride.
