does anyone knows where to find information about fatigue, and performance for bike components??
every brand claims that their products are safe, but sometimes a fork breaks, a stem comes loose, a spoke break...
does any institute makes tests for evaluate quality, and to compare similar products??
why should we spend our money if no one gives guarantee about their products.
just make some browsing for those words "bike+recall", and you'll be surprised with so many mistakes.
No standards, no testing instituteKerry

The short answer to your question is that there are occasional tests done, and a small fraction of those test the right things, and a small fraction of those use valid statistical methods. Multiply these small fractions together and you get a number that is approximately zero.

If you've ever been involved in a standards setting exercise, you know that it can take years to just agree on the testing methods and the standards. And then there has to be some sort of unbiased testing group(s) or something rigorous that a manufacturer can't fudge. And then all the manufacturers have to agree to pay for all of this. What do you figure the chances of any of this happening, let alone all of it.
