I recently purchased a nice used 1992 Merlin road bike and am very happy with it. But I have become slightly paranoid after reading these forums about the potential for cracks/failure in this frame (or titanium frames in general, I also purchased a used 1998 Dean mountain bike last year which I love dearly) based on the seeming preponderance of stories about cracks appearing in the bottom bracket area, dropouts, etc. For background I raced seriously for several years but stopped racing several years ago and weigh around 190lbs, about 25lbs more than my racing weight, and never had a frame fail on me, riding two aluminum frames and then two steel frames.

1. first, is titanium more likely than steel (or other frame materials) to develop cracks (or to be specific earlier titanium tubing)? I understand Merlin provides a lifetime warranty on their frames but I'm not sure if that extends to the second owner, anyone know the answer to that question? For reference the welds on my frame appear clean and well made so I don't anticipate that being a problem.

2. second, I perform all the maintenance of my bike so inspect it fairly frequently. If a crack develops is this something you can "feel" right away or is it usually spotted by visual inspection?

3.third, are cracks typically something that just randomly happen or the result of some stress such as a hard crash?

Thanks for the informative reply, that pretty much answers my questions. I suppose it makes sense if the frame is set up in the jig and welded very well under ideal conditions then it would minimize the stresses on the tubes and joints and minimize the chance of failure.
