Fixed it for you.DaveWC- yes, anything can fail, including a titanium frame.
That last picture is really scary, full weld failure on the top tube, I'll bet whoever forgot to take that bike off the roof rack before pulling into the garage had a really bad day.
I ride a Ti bike, and I'm very happy with it, but I wouldn't hesitate to replace it with a carbon bike if it ever fails or meets with an accident.
Since I've had my Ti bike for over 15 years, that may not be anytime soon, but I wouldn't mind a new Cervelo or Pinarello when the time comes!
Any material can break. Any material can be noodly. Any material can be stiff. Can we stop arguing frame material now? Tires actually make a difference in ride quality. I just got my first pair of Vittoria 25 mm tires, and wow is all I can say. Smooooooooth!
