"Doesn't really work. If you have a front chain ring if any size it will collide with the C section. The locking points are useless, only really letting you lock the wheels and not the frame. BREEAM want 3 dedicated locking points. The industry standard semi vertical rack is spaced at 305mm centers, this looks to be around 600mm so it's no more efficient than a Sheffield stand. The low rack comes out to far to be useful.  If you don't have a rear wall you could knock up a simple angle framework. The racks could also be installed with sheer nuts. 5/10 Could do better."
