I have an Allez sprint, which has dropped seatstays and a w i d e aero post. Here's a list of stuff I'd like to mount:

Frame pump (currently under top tube)
Headlight (mounted on bar tops)
Front camera (can mount on other side of bars)
Taillight (the one I bought that claimed compatibility with aero posts was not so)
Rear camera(I think a saddle rail mount or SWAT mount would work, unless someone can find an aero post gopro mount)
bag (for tube, multitool, tire levers, patch kit, currently using a saddle bag)
2 water bottles (ie no water bottle caddies)

A few issues: a saddle bag means that a SWAT mount or rail mount don't work for the rear camera. I'm open to alternatives that are not "just put it in your pocket" because I hate putting things in my pockets and definitely don't want to deal with falling on hard plastic/metal.

Also I'm looking for rear lights that are confirmed to work *well* with a venge or Allez Sprint aero post. The one I bought is so stretched out that it doesn't clip properly. There's nowhere else to put it because the dropped stays mean there's no space between the brake bridge and the seat tube.

Thanks
