That looks quite good - you dont want to get that much of a larger bag, otherwise the temptation is to take too much and end up with a bike that is not balanced well and is no fun to ride. (A problem I have had with my Carradice.)
I would guess that panniers are the way to go if you want to take a lot more stuff (lower centre of gravity), but again not ideal for a modern racer.
Just pack well, take the minimum you need and travel light.
