Worlds first laser derailleur alignment tool!
Adjusting the rear derailleur is now very easy.

Whether professional, novice or mechanic. Thanks to our unique “Linientreu”, you can set up your rear derailleur in minutes. The Tune Linientreu gets attached by an allen or Torx key on the derailleur mounting bolts. With the aid of the linear laser, the lower and upper stop on the derailleur can be adjusted precisely.

The best thing about it: with our precision laser the derailieur is always set exact.

The tool is suitable for  7-, 8-, 9-, 10-, 11- and 12-speed setups. The “Linientreu” is delivered with a 5mm Allen key and a Torx T25 bit with 25mm length each. All 1/4 “bits fit in the bit holder and other bits can be bought and used depending on the required key width, eg Torx T27 for Campagnolo.

The tune “Linientreu” is patented!
