General Information
A very unique design to these brakes which have a similar design to the Campagnolo Delta brake without the nice front cover to hide the workings.  These were meant to be a more aero design than the older center pull and single pivot brakes, but were not known for their stopping power.  Rear Brake: 42-54mm
