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. This Polygon Thru Axle MTB 2017 & 2018 Standard Mount Drop Out will fit standard Shimano Rear Derailleurs, Direct Mount Shimano Rear Derailleurs with the Shimano adapter, and any SRAM Rear Derailleurs.
