I thought someone here might like to see the bag I designed and had made by Kaibab Gear for $50. On the Marginal Gains podcast they mentioned that a saddle bag is swung side to side when standing, causing some energy loss, and more so on a bike with a really high seat. For aero I'd always wanted a bag that fills the area between my lowered Arundel Aero water bottle and seat tube so hearing the podcast got me to start working on it. The end result weighs the same as my micro seat bag while moving that weight very low. It fits perfectly and looks very aero. It attaches with the lower water bottle bolt on the seat tube znd some patches of velcro. I'll have a taller bag made that uses both seat tube bolts for when I want to carry more.

Nice, I've been considering some kind of custom option for this type of thing. But aren't those aero bottles really awful?

made my peace with a tool bottle and advances in pumps e.g. topeak's two-way have allowed for a pump in jersey pocket.

nice design -is it water proof?

I haven't had a problem with it, but also haven't heard any other reviews. Aero bottle choices are slim. My old Specialized cracked and I think this was the only replacement I found.

The material and stiching look like they'd at least be very water resistant. I only specified that be light, thin, and have a little structure.

It's an interesting concept - I wish one wouldn't have to renounce to the seat-tube bottle cage. I mean, if you are to forgo a bottle, at this point you might well use a "storage bottle" with a sort-of-aero shape. Not being rude, I appreciate the creativity.

I've never used 2 bottles because of weight. I think this is more aero than your idea because it creates a smooth flat serface from the downtube to the rear wheel. The idea isn't mine though, it comes from the Specialized bikes that have storage in the nook between down and seat tubes.
