Serious question here. What is the explanation for the possible failure? The load on a chain is not lateral so what force would pull the pin out - especially if the ends have been flared even just a tad after installation? I ask this because I have done this after a few "oops" moments and after thousands of miles on a single speed where the load can be significant on a steep, lengthy climb (much, much more than a geared bike), there has never been even the hint of failure.
