Posted on 21st, June 2011 about Plasma Chain Device
A very nice chain guide. BUT, it is more finicky on chain line than other brand's offerings. I had problems with mine jamming and rattling, fixed it by moving one spacer from the bb over to the other side, moving the chainring 2.5mm closer to the plate. Now it's silent and smooth. Not as easy to put together as a LS1, but when I bought this it was ̏10 less than a new backing plate for that! Can't argue with economics. So far they're holding up well to a couple of ground outs and the guide will take a 10 or 11 tooth wheel from any major brand with no trouble.
