    I'm considering the idea of filling my hollow frame tubes with grease to soak up vibrations. The idea is to drill a small hole in each tube and install a grease zerk fitting. I would measure the volume of the tube and match the amount of grease fill. All Displaced air would have to be released through the seat tube and head tube through small holes that are usually there already but still using caution in the process to release air and obviously I won't grease the seat tube. Any thoughts on this idea?

    It would be really heavy. The best way to get rid of vibration, is to get rid of it at the source. Best way to get rid of cracks is either beef it all up or build a bike with full suspension.

    I have heard of people using expanding foam in a frame, I don’t think it would really do much. Just make sure all your welding is done first!

    Those are all good points and the "done welding" part too. I'm confident but not enough that I can say for sure I'll be done.
