Acera RD-M360-SGS 7/8-Speed Long Cage Rear Derailleur

What Our Gearhead® Experts Are Saying:

"I installed this derailleur on a gravel conversion and was impressed with how quickly it dialed in. It’s forgiving on setup, shifts consistently across the 7/8-speed range, and the long cage keeps chain wrap managed well. For the price, it’s hard to beat the performance-per-dollar ratio."

The Shimano Acera RD-M360 SGS 7/8-Speed Rear Derailleur delivers value-packed performance for mountain, gravel, and hybrid builds. Its long cage design offers a 43-tooth chain wrap capacity and compatibility with cassettes up to 34 teeth, ensuring riders can tackle steep climbs with confidence while maintaining smooth gear transitions.

Engineered with Shimano’s light-action shifting and Teflon-coated bushings, the RD-M360 minimizes friction for crisp performance ride after ride. The top-normal (traditional) derailleur action ensures intuitive gear changes across the full range, making it a dependable option for riders who prioritize reliability on the trail.

With a direct-attach mount and wide compatibility across Shimano 7/8-speed drivetrains, this derailleur is equally at home as an upgrade or replacement. Rugged yet affordable, it’s the practical solution for riders who demand consistent performance without overspending—keeping bikes rolling smoothly from singletrack to city streets.
