Specialized SWAT Saddle Mount

Uses the two factory bolt holes that are on the underside of most Specialized bike saddles. Holds two 20G CO2 cartridges, has a GoPro mount, and slots for a velcro strap to hold an inner tube or something underneath. I've tested it with the CO2 cartridges in it with some pretty big drops to flat, and it's going nowhere. The slots for velcro straps likely couldn't survive jumps like that.

*Update 5Sep23: Added a CO2 only version.

Uses the same bolts as bottle cage or brake rotor bolts, but make sure the bolts you use are long enough.

I've got a couple ideas of other things to make off of these bolt holes under the saddle, but let me know if you've got any ideas too.
