I took a first test ride today with my 18lb camera bag bungee netted to a rear rack.

The bike is a Felt X:city with no added shock absorption.

Needless to say, the first few bumps over pavement cracks left me wondering what kind of shock my equipment is being dealt and weather it might be above and beyond what's acceptable for it over the long haul.

Anyone have experience with long-term "sensative gear" hauling, positive or negative?

Anything I can do beyond throwing some extra foam around the body and lenses inside the bag?

Am I being too protective?

A lot of questions for my first post, I know, but my goal over the summer is to transition into a totally car-free photographer (it's my only source of income), so I'm looking for guidance and inspiration.

Thanks!
