"This tool has already proved its worth. It's the reference tool for checking and straightening derailleur hanger brackets. Version 2.2 gives an extra offset with a thinner shank to avoid bumping into the frame when untwisting. It was the only evolution to bring to the previous version, which was a Must-Have."
"Excellent tool; but you have to use it tactfully, not gruffly. ... Be sure to read the instructions (which are in French!), so as not to skip any steps. This tool allows you to be autonomous, without having to wait for the local bike shop to return your bike 15 days later. ..."
"This tool is of professional quality, very strong. Its long arm allows you to exert just the right amount of leverage. But be careful: depending on the derailleur hanger, you'll have to go very slowly to avoid breaking it. Straightening a derailleur hanger requires patience!
"Essential tool for aligning the derailleur hanger. Very easy to use and effective. Rear derailleur out of alignment. I suspected the derailleur hanger was slightly bent and ordered the alignment gauge to confirm. In fact, the pictures speak for themselves, with a 20mm gap (to be divided by 2) between the bottom and top of the rim, with the inner-tube valve as a reference. Adjustment done and everything's back in order. The TOP
"Super paratic and easy to use, I recommend."
"Almost indispensable for 1x12 mountain bikes. Allowed me to spare a new derailleur hanger."
"nothing to complain about, works perfectly, very useful"
"Does the job perfectly. A tool I recommend"
"Good material, very solid...I don't regret my purchase...I recommend..."
"Çà allowed me to eliminate the doubt I had about the good condition of the derailleur ar and its 10 years already. A slight straightening of the dropout, then a change of derailleur cable, and I'm off again."
