Thanks.
The aero bottle was a bit of a project. I first wrapped the seatpost in lots of electrical tape, then clamped 2 binder clips to make a flat surface (I removed the silver tab things). I drilled some small holes in the cage and just zip tied it to the seat post. Here is a close-up...
The bottle clips into the cage ok, but still flew off when hitting bumps, so I installed a velcro strap I had kicking around.
I like the aero kit. It holds a mini pump/CO2 inflator (by Genuine Innovations), 2 CO2 cartridges, multi tool, patch kit, and a tube.
Q-rings are ok. Don't expect them to do miracles, I use it to lessen the stress on my knee (miniscus removed). It does muck up my drive train a bit. I am thinking of taking it off to see if it is a placebo.
