Going to be getting the bikes off the floor this week.
Plan was to use these at 90 degrees, with the bike hanging vertically:
Now here's the catch: the walls are plasterboard. Assuming worst case scenario, would it support a bike using correct fixings (something like http://www.qvsdirect.com/plaster-board-fixings?gclid=CJ-Y3NurorgCFXMRtAodqT4AmQ or http://www.toolstation.com/shop/Screws+Fixings/Cavity+Fixings/d90/sd1930)?
Or to put it another way - will I die horribly if I do mount single bikes straight onto a plasterboard wall?
