The Good: These things don't bend, Mines dead straight after a year and a half, Wish i god the black version but i ended up having to settle for purple cause no more black were available, They are super light... I mean come on? 2 ounces? for 25T? Nice and thick too.
The Bad: Only one sprocket bolt hole for it to sit in, so if you mangled that hole your in need of a new sprocket !
Sick sprocket and there is nothing bad i can say about it, dead straight and no teeth are snapped off YET!
