Lots of options for any type of bicycle, but you seem to be limiting yourself by not wanting to modify your current set-up. Can you change the seatpost from Carbon to aluminum or steel? That would give you options for a seatpost rack that could hold 1-2 bags, maybe even a rear rack if you've also got eyelets down near the dropouts (you don't need to load it up, but nice to have the option to strap stuff on). Do you need the Garmin attached to your handlebars or could you just put it in a handlebar bag and look at it as needed? Same with the front light, I never found one of those to be useful during the daytime (a rear light might be a good idea for busy or narrow roads in daylight).
I got to ask, what's with the cameras front and rear? That seems like overkill to me. If I felt a road was that dangerous I wouldn't be riding on it.
