Never had such before and didn't know anything about them. They seem to really work however. Mine is a lowly Deore and I'm getting absolutely no chain slap. I had been thinking about swapping out my stock 40 tooth Bafang chainring to a Narrow Wide but now I don't think I need it. Of course I haven't done any wild down hill but I have ridden pretty fast over some really rough rocky sections of dirt road.
