SHIMANO DEORE RD-M6250 Di2 Rear Derailleur, 12-speed

Robust. Resilient. Ready for anything.
The SHIMANO DEORE RD-M6250 rear derailleur impresses with wireless Di2 shifting technology and the innovative automatic Impact Recovery function.

The flat, wedge-shaped design of the DEORE rear derailleur reduces stone chips and impacts on the trail through its shape alone. In the event of an impact, the smooth outer coating ensures that the rear derailleur can slide off obstacles, effectively preventing damage.

The Impact Recovery function immediately returns the rear derailleur motor to its original position after an impact. In addition, the wide joint structure, the robust aluminium derailleur cage and the solid derailleur pulleys ensure maximum robustness on the trail.

The RD-M8250-SGS rear derailleur with long cage is perfectly designed for combination with a 10-51 tooth cassette. It therefore offers all types of riders an enormous range of gear ratios to master every climb with confidence – at an attractive price-performance ratio.
Details:
• Robust design: A wide link structure, the narrow design, the robust aluminium cage and solid pulley wheels ensure robustness and durability.
• Rear derailleur protection function: The new automatic Impact Recovery function immediately returns the derailleur motor to its original position after an impact.
• SHIMANO SHADOW ES: This development of SHIMANO's SHADOW concept for chain stabilisation is narrower and more robust.
• Precise and smooth wireless shifting: Wireless Di2 and HYPERGLIDE+ technology ensure harmonious, precise and delay-free shifting.
• Wedge-shaped: The new wedge shape of SHIMANO's most resistant rear derailleur to date avoids more direct impacts and glides smoothly over obstacles in the event of an impact.
• Protected battery: The battery is safely shielded so that it does not slip even in rough terrain. It can be easily removed for charging.
