Really great price on one of the best new rear derailleurs out there . I love that it sits back and doesn't get in the way when you drop the rear wheel, not to mention it just looks cool.
The rear derailleur can also be used with a direct mount, making installation of thru axles easier. And the most important to me, who is a cyclist that like mountains but am tall and "heavy", is that derailleur 9100 enabling the use of Shimanos new 11-speed 11-30 cassette.
