For anyone that is not familiar with these, they are possibly the finest handlebar bags on the market. I have one of this size and a medium for my Saluki. I found it best to mount with a decaleur, such as what is sold by Velo Orange, for extra stability on the rack.
The rear bags are nice too, but I'll never give up my rando bags as long as I have a suitable bike to put them on.
Best regards,
