Billy found this spy photo of the new Shimano XT Shadow (looks a lot like sram) rear derailuer. A fixed B-position will keep the Shadow rear derailleur body from smacking into the chainstay but will retain the necessarily adjustable chain gap. In some sense, the new derailleur design wears an additional hanger… which now makes for a derailleur hanger hanger?
