It's the type of kit I stared off with, which I was happy with, sort-of.
I actually started off with a much cheaper generic Far East ebay special which made me nervous every time I put a bar on the top rack.
I suspect the Mirafit rack is much better built and I can see from the photo that the bottom bar connection flange is quite a lot more substantial than the one I had.
So I reckon it's a good place to start.
