High Clamp 28.6

FD Interface - High Clamp 28.6

The front derailleur mounts to the frames seat-tube via a band clamp that is located above the main pivot points of the front derailleur hence the name "high" clamp. A low clamp positions the band clamp below the main pivot points of the front derailleur.
In this case the inside diameter of the front derailleurs band clamp measures 28.6mm in diameter so the outside diameter of the frames seat-tube should also measure 28.6mm to ensure a snug fit. A securing bolt is used to connect the band clamp together and secure the front derailleur to the frame.
A 28.6mm band clamp is only capable of fitting onto a frames seat-tube which is 28.6m or smaller. If smaller then an adapter/shim may be used to fill the excess space.
