Hanger 355 is a replacement rear derailleur hanger from derailleurhanger.com.

What it's for

A derailleur hanger is the small replaceable tab that connects the rear derailleur to the frame. It is made to bend or break in a crash so the frame and derailleur are spared. A bent hanger causes poor shifting that no cable adjustment will fix.
