Jab Drivetrain Compatibility

The Jab derailleur is compatible with most 1x drivetrains!

How is this possible?

There is a unique cable cam (a.k.a. cable fin) for each drivetrain type. The cam is shown in red.

The cam controls the motion of the derailleur for each individual shift, perfectly matching each shifter index point to each cassette cog position.
