Tune Linientreu

For every mechanic, amateur or professional, the Linientreu lets you adjust every drivetrain perfectly!
The tool is placed into the tool interface of the rear derailleur. Then the line laser is adjusted to the cassette. By moving the laser holder you can adjust the upper and lower limit as well as the cable tension perfectly.

This tool works especially well with modern 11 to 13 speed drivetrains that have very small tolerances. It is compatible with all drivetrains from 7 to 13 speed. It is delivered with 25mm length 5mm-hex and T25 Torx bits but you can fit every 1/4" bit to match your bikes.
