A helper tool to eliminate the guesswork of dropper cable installation. 
- Sets gap on posts using a grub screw / grommet on the seatpost end of the cable.
- Eliminates immediate "cable stretch" from the ferrules settling on the housing.
- A true "1 and done" set up! 
- Works best in conjunction with a 3rd-hand tool
- Purple when it wants to be, color may vary.
