Hi there buddy, i've got the same chain on my bike. I think they are the best bmx chains, however, when you first fit it, it will need to 'bed in'. It will need to stretch out ever so slightly for the links to runs smooth, once it does that, you shouldn't no other problems with the chain. If you're still hearing a noise or find its gritty when pedalling, there may be a small chance it could be your bottom bracket. I would suggest bringing it in to any local Evans and we could have a look at it for you. If you have any further questions, feel free to ask.
