 1. Last forever

 ---5 times of lifespan than steel or aluminum steel. Titanium is anti-corrosion from acid,damp,ultraviolet rays even though it is exposed in the air for a long time without any paint. You can put it anywhere as you wish, and don't have to worry.

2. Light weight

 ---Titanium's density is half of steel, which means one titanium frame's weight is half than one steel frame with the same size

3. High Stiffness

 ---Stiffness or rigidity is a important term when we evaluate frame's quality. High stiffness is another word of high pedaling efficiency. Titanium’s stiffness is 28.4% higher than Cr-Mo steel. Titanium frame would make most useful of your pedaling power.

4. Impact absorption

 ---Titanium frame could absorb impact efficiently from ground when your are pedalling.This would reduce athlete's fatigue, and make them feel more relaxed, especially when they are in a tense cycle competition.

If you are a cyclist, a titanium bike would be your best choice. 

 5. Fatigue resistance and Anti-wear

 ---Not like steel, titanium’s property makes it anti-wear and anti-fatigue features. Titanium frame would not break in suddenly, while there will be pre-indication of flaws on the frame surface to warn that a breakage may happen. This avoids accident injury in some way.
