All I can tell you is that in 2001 I purchased a couple of titanium framed Mongoose Pro Triomphe mountain bikes and they were are still are top shelf bikes.I think at the time they were about $2k each. So at least back in 2001 their Pro line was a high quality piece. They currently have several thousand miles on them and the about this only thing I have had to do is replace the tubeless tires several times and few chains and last last had to have the Hayes hydro brakes rebuilt. Somewhere along the line they and many other bike builders lost their way into the mass market place were quality took a back road to quantity.
