We are lucky at work to have a cycling boss so we have secure bike storage and showers however the current bike racks are complete pants – They are the stick your wheel between the bent tubes type which work badly for both Road and MTB wheels. There are not enough of them and they are too close together.

So I have been ‘tasked’ with getting a replacement.
The floor is a concrete slab
The walls are not structural
I think there are about 10 bikes at the moment, but might want room for more, maybe 15.
The bosses suggestion was to make a triathlon style rack where the bikes hang from the saddle, probably constructed from scaffold tubes.
Anyone with any experience of what I should be looking at ?

/starts googling/
