Replacement sprocket for newer ELFs that use the 'UpDrive' system (with NuVinci hub in the middle, not in the rear). Right side freewheel is connected with a chain to a sprocket mounted to the motor's disc brake holes. The motor in the UpDrive ELFs is mounted backwards from a conventional hub motor.
If you need a left side freewheel for an older model ELF, that has the NuVinci in the back, you'll want the ACS southpaw instead.
