Used to be if you wanted to throw drop bars on your off-road rig, you had to fork over your allowance for a new drivetrain and brake levers. Surly made the Corner Bar so you could conduct all your dirt-drop experiments with your current brake and drivetrain setup. I mean, why spring for the whole buffet when all you want is a salty snack at the bar? Anyway, the Corner Bar is made out of Chromoly and it comes in three agreeable widths. A set of shims is included. If you don’t need ‘em, stick ‘em in a drawer for later.
