Even with the compartment on my Domane I can't give up my (very small) backpack. The fact that I essentially have doubled up on whats in the storage makes it funny to me. I also carry a small pump in it which was super handy when I helped a fellow rider out last week.

I'm planning on a longer ride tomorrow. The pack will allow an energy bar, some gels and hydration tabs as well as the stuff I normally carry. As well as a flat kit in the compartment. I hate any kind of a bag on my bike ...weird but thats me .
