I sold my beloved Raleigh carbon road bike a few days ago for a more upright urban/city ride and purchased a new Raleigh Port Townsend. I'm a photographer and would like to safely carry a camera and a couple of lenses, nothing big like a DSLR just my Olympus PEN-F and a couple of prime lenses.

Can anyone recommend a handlebar bag that firmly mounts and could safely carry my gear while riding?

Thank you

Mark
