The Good: This sprocket is amazing! I ride pegless and do a lot of sprocket bashing...rode my last one for 2 years and it had no signs of giving up on me. Bought a new-to-me (used) one 6 months ago just to go with my color scheme and it still rides smooth.
The Bad: Until I have something to say, nothing here!
Ifyou like sprockets that don't suck, spend some money on a Tree.
