Adding rivnuts to alu frames?

I’ve a vitus substance Alu gravel bike and was idly wondering if I could add 2 rivnuts to the top tube for a bag?

Any issue or just don’t do it?

Sounds fine to me, as long as you’re competent enough with the tools

Drill, deburr, check carefully for cracks/chips/damage round the holes, make good if there is any (little round file or something), anticorrosion paint, fit rivnut.

Obvs. use the sharpest drill bit you’ve got!

I personally would cock it up and have that niggle that the frame would fail, so would just stick with velcro…

Put a collar on the drill bit so you don’t lunging through and dint the other side of the tube

Google FEA analysis bicycle frame stress (or similar). Avoid the worst bits
