I'm looking for a spare derailleur hanger for the Triban RC520 GRVL (Decathlon brand), and the one they list on their site is NOT the correct one (per numerous reviews on international Decathlon sites, but also just visually/dimensions).
Here's what they sell:
Does anyone know if this hanger goes under some other name or model? I've seen other hangers (for other bike brands) listed by number (i.e. "#67").
I've gone over numerous websites that list hangers, and this style just isn't there.
As an added note, the derailleur is a Shimano 105 (RD-R7000), and rather than one side being bolted on, the end of the hanger slides between two "fins", and then a bolt goes through everything.
Any help or direction would be appreciated.
EDIT: Getting close! My good friend Ali seems to have a match:
FINAL UPDATE: Decathlon Canada was able to solve this mystery for me! The part is on their website, but not under "derailleur hanger" as you might expect, but as a "derailleur dropout" and doesn't list the RC520, despite being the exact part: https://www.decathlon.ca/en/p/8611184/derailleur-dropout-edr
As an alternative, I could use the other one they sell + a Shimano "Bracket Axle Unit" P/N Y3F398020, but I'd rather simplify and will wait for stock to return on the standard part.
