Safe to keep frame-mounted CO2 cartridges in contact with down tube?
I bought a Birzman Sheath Apogee combo frame pump/CO2 inflator with a mounting bracket. Unfortunately I wasn't thinking about how my bike's down tube is wide rather than cylindrical and therefore the CO2 cartridges touch the frame. Is it safe to leave them that way or should I move the bracket to the seat tube?

Bikes are okay, I guess.

Just put a piece of tape or two between cartridge and frame to protect it. It will probably be okay.

Whenever I've needed bottle cage spacers I've disassembled a chain link to use the rollers. They are the perfect size.

#10 stainless steel washers are dirt cheap, and perfect for 5mm screws.

Duh, I should have thought about using some washers. I was even at the hardware store twice this weekend and it didn't occur to me. Might need longer screws too, I'll have to see what I have.

Wrap some old inner tube around your CO2 canisters and keep them snug against the downtube might be a better option, because unless they are mounted with a really rigid mounting platform, that mount is going to vibrate as you go through rough roads causing the canisters to vibrate against the downtube as well.
