Long Cage Rear Derailleur (12-speed)
Deore XT RD-M8250-SGS
The new Deore XT M8250 long-cage derailleur paired with a standard 10-51T M8200 cassette gives riders and racers the speed, range, and robustness to tackle every trail on the mountain.
It features built-in Automatic Impact Recovery, an impact-deflecting shape, and simple covered-pulley solutions. The derailleur stands up to harsh trail impacts and still retains its lightning-quick shifting speed and top-level performance.
The derailleur is fully wireless, with a BT-DN320 battery inside the derailleur. The battery is taken off the derailleur for charging.
RD Protection Function: The new Automatic Impact Recovery function instantly returns the derailleur to its original position after impact. Protected Battery: Tucked safely inside an enclosed space, the battery won’t budge even in rough terrain, while remaining completely removable for charging.
Battery charging
Charging these batteries is easy - you take out the battery, pop it in the charger, and that's it. After about an hour the battery will be fully charged, and you're good to go.
