Long Cage Rear Derailleur (12-speed)

GRX RD-RX717-SGS

The new GRX RX717 is Shimano's cheaper version of the GRX 1x12 RD-RX827.

It is a wireless 1x12 long-cage derailleur, that can be paired with any Shimano 10-51T MTB/Gravel cassette.

Just like the 'very' similar Deore M6250 rear derailleur, 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.
