The new XTR derailleur also comes equipped with SHIMANO’s cutting-edge automatic impact recovery function that allows it to smoothly pivot away from trail obstacles to lessen the force from impact and then quickly return to its original position once past the impediment. It's almost like having a second set of eyes watching for trail hazards, then reacting in real-time so there's no interruption to your ride or race.
Derailleur durability is further enhanced by the component’s wide link structure, tough carbon skid-plate, and solid pulley design that together make it bomb-proof.
It’s your new mountain biking security blanket, allowing you to stay totally focused on the trail ahead.
This industry-leading durability is combined with SHIMANO’s new chain stabilizing technology, where a dual spring design creates higher chain tension for better chain wrap and retention—and reduced chance of skipping or dropping your chain.
Powering all this advanced technology is a long-lasting rechargeable battery that’s tucked safely inside the rear derailleur body, completely sealed off and secured so you can confidently tackle rough and rowdy terrain.
The new XTR Di2 system features two wireless rear derailleur options, a traditional long cage for use with the 10-51T cassette and a mid-cage model with a 9-45T cassette that offers increased ground clearance without gearing range loss.
In either case, you'll reap the benefits of SHIMANO's blazingly fast and durable 12-speed HYPERGLIDE+ shifting, which is now even faster with SHIMANO’s wireless Di2 protocol.
