Because of the amount of rain and muck around here I just replaced my chain with an SRM powerlink chain. I want to be able to take the whole thing off for good cleanings. So far no problems, it is easy to take on and and off and no chain slipage or anything else -even during sprints and steep hills, but I am not heavy (in fact quite light at 103 lbs) so that may be a factor.
To take mine off I have to bend the link so that I can push the plate forward and off. It feels like it takes about 3 hands, but I can get it off. Putting it back on is easy.
