Description
This Shimano Altus M310 7/8 Speed Rear Derailleur features an advanced light-action, long-cage design with Teflon-coated bushings. What sets the Shimano Altus derailleur apart from other rear derailleurs is its unique 13 tooth upper and 15 tooth lower pulleys that provide a 43 teeth chain wrap capacity (more than conventional 11 tooth pulleys) and enable them to rotate with less friction.
