Hard to find objective data on the net.... or anywhere for that matter.

The reference to ATM in the Zinn Q&A I posted got me curious. One search came up with this so I guess if you want to do more research, you could spend some money on the test reqs.

I also found some references to testing labs like this http://www.microbac.com/testing-serv...onent-testing/, and testing papers like this one http://www.oemcarbon.com/2012/08/fat...bicycle-forks/

and this one: http://www.wpi.edu/Pubs/E-project/Av...cycle_Fork.pdf.

So if you are inclined toward caution, I infer from fact that I found these various things among the top results with one google search, that there are both bike industry-affiliated and independent resources available to get some of the data you seek.
