The BMC Dropout No. 58 Rear Derailleur Hanger Black is a classic-mount rear derailleur hanger built to restore precise gear shifting on compatible BMC bikes. It’s designed for 11-s peed standard derailleurs including SRAM 11-speed, and Shimano 11 and 12-speed options, helping keep your rear mech sitting true for cleaner, more reliable shifts. The hanger uses a SHIMANO B-link connection, and it should not be used with SRAM 12-speed derailleurs for best results. Show more
