Specialized Mtn Hanger 4 Alloy w/Bolts Features
The Specialized MTN4 Derailleur Hanger is an OEM replacement part for a number of Specialized and S-Works mountain bikes. To choose the correct derailleur hanger for your bike, it is important that the hanger is identical in appearance to the one it is replacing. Carefully compare images with the actual hanger to ensure that the shape is the same and that the bolt holes are in the same location
