MrKnopfler on April 9, 2025 12:20 pm [Here’s the parts list](https://si.shimano.com/es/pdfs/ev/RD-R7150-4927/EV-RD-R7150-4927C.pdf). from shimano website. Doesn’t seems like they consider that a replacement part, but more like the “derailleur itself”, so no original replacement from shimano. Sorry mate.
