Product Description


Shimano Alivio M4000 9-Speed Rear Derailleur

Shimano Alivio rear mech for 2x9 or 3x9-speed mountain bike drivetrains

  • This great value Alivio rear derailleur offers crisp performance for mountain bikes with 9-speed cassettes
  • Also suitable for touring / hybrid bikes with triple chainsets and 42 or 44t big ring
  • Shadow design with smooth skid plate surface features a super low profile design that reduces the risk of damage from trail side hazards
  • Wide link design increases rigidity and service life
  • Alloy body and outer link for lower weight without compromising strength and durability
  • 11-tooth pulleys for reduced pulley wear and chain noise
  • Advanced light action design with low friction fluorine coated link pivot bushings
  • Designed to work best with 9-speed cassettes with 32-36 tooth big cogs
  • Recommended total capacity: 45 teeth
  • Top-normal swing design - this mech moves the chain runs to the smallest cog when the gear cable is at minimum tension
  • Designed to work best with Shimano Hyperglide 9-speed cassettes and chains

Shimano Alivio
Half way up the Shimano hierarchy, the Alivio rear mech benefits from being fundamentally similar in shape, profile and technology to a Shimano top-end XT/XTR mech - albeit using less exotic and less lightweight materials - while being noticeably more sophisticated and built to finer tolerances than a Shimano entry-level Tourney mech. This Alivio mech is a perfect example of why mid-range Shimano is almost always a best buy in cycle components.
