I hesitated for a long time whether to buy such an expensive tool. And right after the first use, it was clear to me that I should have bought it right away and I would have saved tens (hundreds?) of euros on all kinds of improvers that were supposed to improve the shifting. The basis is simply a straight heel. I was dissuaded from buying the fact that after a few times that I had my foot straightened in different services, the result was not ideal and convincing, so that I could secure a straightener. But I guess I was unlucky every time with reluctance. Now I fixed it on the first shot myself and I didn't even strive for every single millimeter (which is certainly possible with this tool despite the slight wobble of 1.1 mm, the cheaper one from Super B has 1.5), but it was enough for me to be within the tolerance of 3 millimeters (the included instructions even state 4 mm). So: absolute satisfaction and solved a long-standing problem

SK drahô, aľe kvalitnô, len v rodine mám 7 bikov, a konečne môžem naladiť radenie k mojej spokojnosti a v priebehu pár minút, takže som ho hneď použil na všetkych strojoch v garáži a bolo treba aj kde som si myslel, že netreba

SK Skvelý a šikovný nástroj, bezproblémové používanie, kvalitné prevedenie, síce je potrebné do toho investovať peniaze, ale oplatí sa, ak si chce človek pomôcť sám s opravou a nemusí byť viazaný na bike servis.

It is not the cheapest, but when the foot of the derailleur is welded on the frame, it is advisable to use a quality tool.
