I heard somewhere that in racing there are serious bike mechanics who fill mountain bike frames with expansion foam to reduce noise, damp vibrations, and in some cases, actually make the frame stronger. But like anything in racing, it could be that this “upgrade” takes a lot of work, has limited gains, and could potentially ruin a very expensive frame. It could also be that very specific foam is being applied strategically—instead of, you know… a haphazardly applied $6 can of expansion foam from the hardware store.

So before you go and fill your carbon or alloy mountain bike frame with expansion foam, I’m here to test it out and tell you if it’s worth it!
