Surly Midnight Special 650b - Black

The 650b version of the Midnight Special — same do-it-all attitude as its 700c sibling, but rolling on plush WTB Horizon 650b x 47mm tires for even better comfort on rough pavement and light gravel. A simple, reliable SRAM Rival 1 drivetrain keeps maintenance easy and gear-changes crisp.

When the pavement turns to potholes, then gravel, then back again, the 650b Midnight Special soaks it all up without complaint.
