I took the time to use it several times before commenting and sincerely I am very satisfied.
Having a Cannondale frame with unusual shape I was nervous, and no, all is well.
Fully adjustable, the bike is somewhat positioned exactly as desired, with excellent support and even blockage of convenient handlebar.
In addition, stability is to RDV with not 3 but 4 feet and even magnetic door shelf tools ...
For those who are searching, I recommend it!
