Titanium is a pretty soft* material (*soft in terms of superficial strength, it can be scratched by iron, steel, glass, sand, diamonds, etc.. now sand and diamonds, are not a problem, but even crude iron ore can scratch Titanium). So avoid rubbing the frame too often, and also avoid cleaning the frame dry (you would rub the frame with the hard dust particles that it collected).

Otherwise Ti is light, very high strength, it stays strong even at high temperatures without bending, does not corrode, etc
