On my Pashley, I want the bike to be functional. I have some larger clip on panniers for the rear rack, but I wanted a larger saddlebag to carry a waterproof, saddle cover, and still have a bit of space for a bottle of milk (or wine!!) if I am out and about.
The obvious choice was Carradice - handmade in Nelson, Lancashire, UK, these are old favourites amongst touring cyclists, so couldn't resist. I bought the Carradice Barley, and it fits on the saddle and rack wonderfully.
I'll be doing a fuller review of the bag in due course (when I get around to a review of the bike itself!). In the meantime, here is a picture!
