I keep my bike frame as uncluttered as possible. I have two water bottle cages and that's about it. The drop bars do have the Garmin computer holder. I don't even have a saddle bag. So my topeak road morph and spare tubes all go in my lumbar bag that's clipped around my waist. That lumbar bag carries more stuff than a seat bag. Its portable, unlike a seat bag.

I have asked Columbia to design a lumbar bag, not just for trail runners and hikers, but one specifically for bike riders. No response yet.

Patentcad has a beautiful bike. IMHO, attaching a frame pump onto his bike would take away the aero qualities from that Cervelo.
