RD-R9250-SS - Short Cage Shadow Rear Derailleur (12 speed) image

Shimano are likely to introduce DURA-ACE R9250 sometime 2021. Not much is known about this yet, but this is going to be a 12 speed system, semi-wireless and that it'll use a new battery, the BT-DN300.

This derailleur features a charge port, LED, button and an EW-SD300 type port used to connect the derailleur to the battery.

CyclingTips wrote a pretty good article on the new system (speculation), read more on their page.

Note that the derailleur pictured on this page is the previous generation DURA-ACE derailleur, not the RD-R9250.

BikeRadar published a page on prototypes of these derailleurs being used in races, with photos shot by Cor Vos.
