Excenter Bottom Bracket

The integrated chain tensioner for bikes with Rohloff Speedhubs or Singlespeeder

A more clean and neat look of your Marschall bike is impossible. This integrated, ingenious BB banish the unaesthetic chain tensioner you see on every other Rohloff bike. And it follows Bernhard Rohloff´s idea of a maintenance-free drivetrain. Chain tensioning is executed directly on the BB. Reliable, precisely and durable.
