Surly Midnight Special Frameset 64cm Hot Mayonnaise. The Midnight Special is a road plus compatible frame 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 matches perfectly with 650b road plus tires ready to eat up road chatter and absorb all the bumps in the road for a much more comfortable ride.
