2004 model used for woods riding. The OEM chain was replaced with a Marshal chain last year. The rollers over both master link pins have broken. I can't figure out why so time for a new chain (and rear sproket). I'm looking for an oring chain that can be clipped or rivited and is otherwise comparable to the OEM chain. There are a lot of flavors of 520 oring chains and it's hard to figure out which one is the same quality as the original.

Thanks in advance for any assistance.

I've had great luck with Regina gold chains.

I have been using DID ERT520 chains for ever and a day with great success. I have plans to change out both sprokets and chain before riding season and exploring going to O-ring style chains. Not sure what I will do but certainly staying with what i have been doing is pretty darn good.
