Hello All, About a month ago i decided to put on a new chain (just because it was getting old). I bought new stock sprockets and a DID 520 120. A month later, the chain broke on me. i bought a Renthal Gold 520 120 and on my second ride the chain broke (in many spots, all on the outside). Why is this happening? It is becoming expensive and frustrating. - The tire was aligned properly - The sprockets are not warped - The chain tension was to spec. I did notice that the rear chain guide rub block has a small piece broken on the rear left side... could this be an issue? Any insight?? Also, should i get an x-ring instead of o-ring??
