I’ve been running them all winter and couldn’t be happier with them. As claimed they doo see to be easier of the chain, as far as being quiter I don’t know or much less care. I have snapped a few though, they will not hold up to Bandi’s curbs :idn: I’m planning on running them for the rest of the season at CRE, IMI, and GJ though. We get ours from Acceleration Karting in Vegas, 14.99 for one and they get cheaper if you buy more.
