All-City Super Professional 2-for-1 derailleur hanger - Stainless Steel

All-City Super Professional drive side derailleur hanger aka 2 For 1 Drive Side Dropout. We custom 3d print these hangers -- we reverse engineered them after they were discontinued rendering bikes unrideable after a broken hanger. 

These hangers are SLM printed from 316L stainless steel meaning they are very durable and will not crack or break like the OEM hangers did. Stainless can be straightened if bent, meaning this should be the last hanger you will ever need to buy for your bike.

This does not include the 5mm bolt, outer thru-axle cap, or the tensioning bolt. We recommend leaving the tensioning bolt off -- the thru axle holds the dropout in place and the bolt never worked well in our opinion. The hanger will work with that tensioning bolt if you choose to reuse yours but we find it isn't needed or useful.
