Excellent article that fulfills its role perfectly but beware: 1- screws are supplied without plugs, which are absolutely necessary. Also, if you get me on as a plasterboard ceiling in place, be sure to prepare molly bolts (hollow wall), otherwise your bike will eventually land! 2- the manual does not explain how absolutely pass the rope pulley in the survey, and this is a bit complicated for those who, like me, have hardly any memory of their being 2nd class mechanics. Warning to spend 2 times the rope in the hole on the inside and not outside (otherwise you will damage the rope ... I have paid the price).
