Charlie says... I use one of these on the bars of my 29er fixie... its really handy, big enough for most things that you might need including beer and cheese.
The Zip roll is a compact bag which is easy to fit to the saddle or handlebars. Its neat form means it’s ideal for carrying just your essentials whilst also looking the part with its smart, timeless design. A zip opening and covering flap keep the worst of the British weather out too. The Zip Roll is small enough not to need an additional support brackets.
