Altus M310 7/8 Speed Rear Derailleur

The Shimano Altus M310 is a 7/8-speed rear derailleur built for hybrid and commuter bikes across India. Whether you're threading through Pune traffic, grinding up the Ooty ghat roads, or logging weekend kilometres around Hyderabad, this component delivers consistent, predictable gear changes without demanding constant attention or expensive upkeep.

Use Cases

Daily training. Reliable use across Indian training conditions — heat, humidity, and rough tarmac.

Race day. Performance-grade construction for competitive efforts.

Long rides. Built for full-day rides across Western Ghats, Sahyadri, or Nilgiri climbs.

Our Take

For riders on hybrid builds in India, the Altus M310 sits in a sensible sweet spot — more dependable than the cheapest no-brand options, and priced well under Alivio or Acera without sacrificing day-to-day function. In Mumbai and Chennai's monsoon months, where grit and standing water punish drivetrains hard, the M310's mechanical simplicity means easier field fixes and predictable shifting even when conditions are hostile. At Rs. 1,890, it's an honest, durable choice.

Sizing for Indian Riders

This is a drivetrain fitment question, not a body-size one. Confirm your existing cassette is 7 or 8-speed, that your shifters match (7 or 8-speed indexed), and that the total capacity suits your chainring-to-cassette spread. If upgrading from a worn derailleur, check the hanger thread and cage clearance. The M310 is designed for hybrid geometry — not drop-bar road builds.

Compatibility Notes

The Altus M310 is compatible with 7 and 8-speed Shimano drivetrains. Pair it with a matching 7 or 8-speed indexed shifter for correct pull ratio. Works with standard rear derailleur hangers. Not intended for 9, 10, or 11-speed cassettes. Mixing with SRAM shifters is generally not recommended due to differing cable pull ratios. Replace shift cable and housing during installation for best results.

Pairs Well With

For a complete, reliable drivetrain setup, consider pairing this derailleur with a quality wet-condition chain lubricant for monsoon riding, a 7 or 8-speed cassette, indexed trigger shifters compatible with your speed count, and replacement inner and outer shift cables.
