Check the complete fit

The supplier lists compatibility with Shimano 12-speed MTB rear derailleurs. Match your exact derailleur, pulley position, tooth count, mounting bolts, spacers and cage clearance before ordering. Road-bike and other-brand derailleur compatibility is not supplied.

The supplier recommends installation by a trained professional. Follow your derailleur's service instructions for pulley orientation, assembly and bolt tightening; do not assume every Shimano derailleur uses the same setup.

Includes two Gold pulley wheels with bearings and dust caps. A derailleur, chain and replacement mounting bolts are not listed as included. No guaranteed shifting or friction improvement is claimed.
