The SRAM Rear Derailleur Inner Cage X01 Eagle (52T) Polar Including Screws is a genuine replacement part designed specifically for SRAM X01 Eagle rear derailleurs. This inner cage is engineered to work seamlessly with wide-range Eagle cassettes up to 52 teeth, helping to maintain crisp, reliable shifting across the full gear range. Using an original SRAM cage ensures that chain management, tension, and shifting performance remain as the derailleur was intended, which is especially important for aggressive trail and enduro riding where precision and durability are critical.
Finished in a sleek Polar colorway, this inner cage not only restores function but also keeps your drivetrain looking clean and modern. The kit includes the necessary screws, making installation more straightforward and reducing the need to source small hardware separately. It is ideal for riders who have damaged their existing cage through impacts, crashes, or long-term wear, and want to refresh their derailleur without replacing the entire unit. By choosing an authentic SRAM replacement, you help extend the life of your X01 Eagle drivetrain and keep your bike shifting smoothly on every ride.
