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!
