More Information

The SM-AD91 is Shimano's band clamp adapter for braze-on type front derailleurs. If your frame has no braze-on tab on the seat tube, the adapter clamps around the tube and gives the derailleur a proper mounting point.

It comes in two diameters. Check your seat tube diameter or frame specification and choose the size that matches.
