Jab Derailleur Cage Options

There are 2 cage options for the Jab derailleur. Most modern 1x drivetrains work best with the long cage, but the cage selection will depend on the tooth count of the largest cog (gear) on your cassette.

Long Cage

  • Cassette tooth count: 44 teeth to 52 teeth (largest cog).
  • Pulleys: 14T upper, 14T lower.
  • Typical use: 1x MTB, wide range 1x gravel, and eMTB.

Short Cage

  • Cassette tooth count: 40 teeth to 46 teeth (largest cog).
  • Pulleys: 14T upper, 14T lower.
  • Typical use: 1x gravel race gearing, and narrow range 1x MTBs (such as 11 speed).

Chains

Compatibility: The pulley teeth and cage fully compatible with 12, 11, 10 and 9 speed chains, including T-Type chains and flat-top chains. 

Cage Lock

Every Jab derailleur has a cage lock feature that makes removing and installing your wheel easier. You can insert a tool (such as a 4mm hex or T25 torx) to hold the cage in place and remove the chain tension.
