Must say, I am always a bit miffed with these new fangled powerlinks.
I grew up with 1/8th chains having those U shape connectors, which always had to be put on the right way and then when I had proper racing bikes with 5 speeds blocks and 3/32nd chains, they never came special links or pins and always had to be joined using a chain splitter.
Now with 9 & 10 speed links, I do normally use the connecting links they come with, but the last couple of changes I did earlier in the year, I didn't bother with the connectors and just used a chain splitter tool to re-join the links. Had no problems and never had a chain break, but I do carry the splitter with me just in case.
So I am not entirely convinced that the powerlinks are essential and have just been introduced to cater for those who are technically incapable of using a chain splitter properly.
Does anybody have sound reasons why the powerlinks have to be used or any feedback from not?
