Strengths: It allowed me to run a 1x7 setup without any chainguides. It's still working and straight after it hit a rock.
Weaknesses: The crank bolts keep getting loose at first. Kept on tightening them. The thing is durable but it doesn't really give you that confidence.
A little expensive here in the Philippines. I couldn't find any other single speed crank at the time and I bought this. Seems to work fine for what I need it to do. The Hooka DH and a used Shimano Saint crank only cost twice as much and there's a world of difference between them.
