As per the title, I am selling a Shimano XTR Di2 rear derailleur (model M9250-GS with medium cage) including an XTR 12-speed cassette with 9-45 tooth gear ratio.
The components were removed from my new bike after only two rides (approximately 8 hours total) due to a switch to the SGS version, as I installed the 51-tooth cassette.
Perfect for those who do Gravel or MTB on fast courses, as this GS version is more compact and stable.
It is the model also seen on the Team Ineos bikes at the latest classics (Paris-Roubaix). Condition: Like new, no obvious signs of wear.
Compatibility: Max sprocket 45t.
