Rear derailleur hanger for Polygon STRATOS S5.
Can be used to replace your rear derailleur hangar if it is bent.
Drop outs (derailleur hangers) are a sacrificial component of your bike, designed to bend or break in the event of an accident - saving your frame from being damaged. Always have a spare, as the bike is un-rideable without one.
Specifications:
Cast Aluminum.
Comes with 2 mounting bolts included.
