Personally, I will take Sheldon Brown's word for it (and most if you too). I ride 1/8" Track, but I can't see how a bike that rides 21days through the Tour de France has a weaker chain than my Wipperman Track Chain.

That being said there are some road chains that you need to avoid when riding fixed. Some of the cheaper road chains have weird master links that if you put back pressure on, will actually pop. I believe TAYA may have a chain that does this, but I am sure it is not the only one.
