Designed to withstand the extreme demands, the new rear derailleurs is purpose-built to take rock strikes and hard impacts. The derailleur's low-profile design helps it avoid blunt force impacts, while the unique wedge shape allows it to glance off trail obstacles. With the Shimano Shadow ES, it uses a slimmer, stronger evolution of Shimano’s pioneering chain-stabilising SHADOW concept.
Automatic Impact Recovery
When an impact happens, the rear derailleur features SHIMANO’s new automatic impact recovery function. This allows the derailleur to pivot away from the trail obstacle to lessen the force of the impact, and then it snaps right back into place.
Durability
Ready to take on the toughest trails, the rear derailleur is built with a wide-link structure, an alloy solid pulleys for added durability. It utilises SHIMANO’s new chain stabilising technology with a dual-spring design to reduce the chance of skipping or dropping your chain. This comes thanks to a higher chain tension for better chain wrap and retention.
Battery Protection
The XTR wireless Di2 derailleur is powered by a long-lasting rechargeable battery that’s tucked away inside the derailleur body. It is sealed off and very secure.
A Shifter That Shifts Fast
The XTR M9250 SHIMANO RAPID ES shifter feels instantly natural out of the box, but can also be molded to fit any hand, thanks to its familiar fit and evolved adjustability design. Multiple shift modes, like hold-down multi-shift, tactile click-through double shift, or locked-out single shift, deliver precision, while a tube able third button allows for additional system tuning or third-party connection.
