Shimano Altus RD-M370 rear derailleur, 9-speed

The Altus RD-M370-SGS is a long-cage 9-speed rear derailleur built around Shimano's MEGA 9 drivetrain design. The action is light and smooth, which is what you want on a bike that gets ridden daily rather than raced, and it is a straightforward replacement for a worn or damaged 9-speed Altus derailleur.

Highlights

  • 9-speed rear derailleur
  • MEGA 9 drivetrain design for smooth, light shifting
  • Long cage
  • Black

Light action where it counts

MEGA 9 is Shimano's 9-speed drivetrain design, and the RD-M370 is tuned for low shifting effort rather than outright speed. Over a long commute or a loaded ride, a lighter shift is one less thing working against you.

Compatibility and fit

Shimano 9-speed drivetrains, long cage. Check the maximum sprocket and total capacity your gearing needs against Shimano's figures for this derailleur before ordering, and confirm your frame uses a standard derailleur hanger. If you are not sure it will wrap your cassette and chainring range, ask us first.

Shimano warrants this rear derailleur against defects in materials and workmanship. Normal wear is excluded, which here means the jockey wheels, bushings and pivots wearing out with use, along with crash and impact damage, bent or damaged derailleur hangers, and damage from incorrect fitting or adjustment.

Warranty claims and returns are handled by Tune Cycles. Contact us with your order number, send the part back to us, and we will assess it and lodge the claim with the distributor on your behalf. Please do not send the part to Shimano directly.
