Shimano M4000 Alivio 9-SPEED Derailleur

Shimano M4000 Alivio 9-Speed Derailleur

The Shimano M4000 Alivio Shadow design rear derailleur was drafted up and pieced together to take on more unforgiving riding conditions. Through its low profile and single tension construction, the Shimano M4000 Alivio 9-Speed rear derailleur keeps chain slap at bay even in the most ruthless riding conditions. The result is a reliable rear derailleur that fights rough and rowdy with smoothness and silence; a valuable choice for the recreational and avid mountain cyclist alike.

Features:

  • Speeds: 9-speed
  • Shimano Shadow technology for prolonged durability and simple operation
  • Rear cable adjuster
  • B-tension spring for easy wheel installation
  • Direct mount compatible
  • Compatible with 11-32, 11-34 or 12-36 teeth 9-spede cassettes
  • Not compatible with 11-28 teeth cassettes

Highlight of this groupset
I recently got the entire M4000 groupset to upgrade a bike, and I am extremely impressed with the quality of the new Alivio lineup. Easily better than the older Deore setup on my other bike. In particular I was extremely impressed with the premium feel of this derailleur. It's definitely eye candy on a bike and features Shimano's shadow technology. It's also direct mount capable which is awesome . Even on a standard mount though, this derailleur has performed really well. Very crisp, direct, and responsive. Great chain control and little chainslap to speak of over the rougher stuff.

Works very well as 10 sp wide range road derailer
I bought this derailer so I could shift a 10sp 11-34t Shimano cassette with Microshift bar end shifters. This derailer is not the Dyna sis system so it uses shifters that work with Shimano road derailers. I use this system with the shifters set to friction. This is the smoothest and best shifting system I own. It shifts easier and crisper that my XT Shadow Plus MTB and my Deore Shadow Plus MTB rear derailers. I'm amazed and very pleased with this derailer. Easy to install and the service and price from Jenson was great.

I would like upgrade my 2015 Trek Marlin 6. Will this work with Altus 8 speed groupset(M310 shift lever, M131 42/34/24 crankset, HG-31 11-34 cassete) ? If not, what rear derailleur would you suggest? Thank you!

BEST ANSWER: Should be fine. All Shimano 7, 8 and 9 speed mountain rear derailleurs have the the same leverage ratio. 10 speed mountain mechs have different leverage.
