Rear derailleur GS

Optimised to withstand impacts, the M9250 12-speed medium cage rear derailleur is the choice of top enduro athletes from Shimano and weight-conscious cross-country riders, especially when paired with the compact 9-45 cassette. Featuring the brand new wireless Di2 shifting, automatic recovery after impacts, a redesigned triangular shape, and an extra 23 mm of ground clearance to ride without the risk of hitting debris, this rear derailleur stands out for the speed of its shifts and its ability to keep you competitive on any terrain.

• Robust design: the wide joint structure, the protective plate design, the durable carbon plate, and the solid pulley add to its toughness and longevity.
• Rear derailleur protection function: the new automatic impact recovery function instantly returns the derailleur to its original position after a shock.
• SHIMANO SHADOW ES: a finer and stronger evolution of the pioneering chain stabilisation concept Shimano SHADOW.
• Clean and precise wireless shifting: the wireless Di2 combined with HYPERGLIDE+ technology allows for smooth, accurate, and instant shifts.
• Triangular shape: the new triangular shape of the strongest rear derailleur from Shimano to date avoids the most direct impacts and smoothly rebounds off rocks in case of a shock.
• Protected battery: securely integrated into a closed space, the battery won't move even on rough terrain, while remaining completely removable for recharging. * Battery sold separately.
