Shimano Altus RD-M370-SGS Rear Derailleur - 9 Speed | Long Cage
What Does the Shimano Altus RD-M370-SGS Deliver on a 9-Speed Build?
The Shimano Altus RD-M370-SGS is a long-cage 9-speed rear derailleur built for budget-conscious trail and mountain bike builds that still need reliable, consistent rear shifting. The SGS long cage handles wide-range cassettes and triple chainring setups, providing enough chain wrap capacity to move cleanly through the full gear range without chain slap or slack issues. Both the upper and lower pulleys are 11-tooth, maintaining proper chain angles across the range and keeping drivetrain noise low during normal riding conditions.
The derailleur uses Shimano's standard 9-speed MTB actuation ratio, making it compatible with any Shimano 9-speed MTB trigger or Rapidfire shifter including Altus, Acera, and Alivio units. The construction is lightweight but durable, suited for trail riding and daily commuting where consistent performance and easy maintenance matter more than grams saved. If you need an affordable long-cage 9-speed derailleur that shifts correctly and handles a full gear range without drama, the RD-M370-SGS is a dependable choice.
