Right now i have JT Steel sprockets on my bike, with a Regina RX3 chain (non o-ring). The chain is basically useless now.. I am looking for advice for the best chain to get.. I will stick with the JT Steel sprockets (new ones of course).. I ride trails only, with A LOT of mud, and dust.. What is the best type/brand of chain i can get. I tried a search but didnt come up with an answer.. This is for my 426. Also, will i need a spacer with these chains you guys suggest..? Thanks!
