Shimano Deore RD-M5100 11 Speed Rear Derailleur
Who's this item for: Anyone with a Shimano 11 speed drivetrain that wants to upgrade to a wide range setup. Pair this up with a new longer chain and a wide-range cassette and you'll be good to go.
Number of gears: This is an 11-speed derailleur.
Chain and cassette compatibility: This derailleur is designed to pair up with the Deore CS-M5100 11-51t cassette but it'll also work well with other wide range 11-speed cassettes.
Max cassette range:
- Minimum sprocket size: 11T
- Maximum sprocket size: 51T
- Total capacity: 40T
Jockey wheel tooth count (top / bottom): This derailleur uses 13T pulleys top and bottom.
Pros: Unlocks the potential for wide-range gearing on 11-speed MTB's. Awesome price point.
Cons: Deore level derailleurs use bushings on the jockey wheels rather than the bearings found on higher-end models.
Spinners get dinners!
I grabbed this dude initially to give my trail bike a bit more legs for a bikepacking trip (will take a 51t cass!) but it actually works so well that ima just leave it on! Thanks MTB Direct!
