Shimano Deore Di2 M6250-SGS 12 Speed Upgrade Kit - Bar Clamp

Shimano DEORE Di2 RD-M6250-SGS 12-speed Rear Derailleur

Robust, indestructible and ready for anything. The DEORE Di2 RD-M6250 12-speed rear derailleur with long cage from SHIMANO features the brand new wireless Di2 shifting technology and an automatic impact recovery function - immediately returns the derailleur motor to its original position after an impact.
What doesn't get hit can't get broken - the flat, wedge-shaped design of the new XTR rear derailleur prevents most stone chips and impacts on the trail. And if an impact does occur, the rear derailleur can slide off obstacles on the trail thanks to the smooth outer coating, preventing catastrophic damage. The automatic impact recovery function immediately returns the derailleur motor to its original position after an impact, while the wide joint structure, durable plate, skid plate design and solid derailleur pulleys ensure robustness and durability.
