Guest Posted December 4, 2011 Share Posted December 4, 2011 Hi guys and gals have a question regarding buying a new chain I have a yuan renegade xgj-125 and my chain is very loose and keeps jumping off the sprocket as I do use this as an everyday commute ( about 40 miles daily) I was hoping I could use a heavy duty chain instead of a standard 520 now my questions are do I need a specific chain or would any 120 link chain be ok? Is there a difference between link sizes? And is a x link chain better than an o link? Thanks for reading people Quote Link to comment Share on other sites More sharing options...
Bogof Posted December 4, 2011 Share Posted December 4, 2011 Have you tried adjusting it?You really should stick to the correct size and pitch. All sorts of problems await you if you get it wrong. Quote Link to comment Share on other sites More sharing options...
Guest Posted December 4, 2011 Share Posted December 4, 2011 Yeah it's adjusted all the way back on the adjusters so will be needing a new one nd was hoping to be able to buy a decent one off eBay that's a little stronger than a standard one any advice?

So long as the pitch is the same you should be fine. If it's that worn you might want to check the sprocket too. Quote Link to comment Share on other sites More sharing options...

CheshireCBR Posted December 4, 2011 Share Posted December 4, 2011 I always change the front and rear sprockets with the chain, that way you cant go wrong Quote Link to comment Share on other sites More sharing options...

XmisterIS Posted December 4, 2011 Share Posted December 4, 2011 best to change chain and sprockets all at the same time.IMHO, go for DID X-ring. Quote Link to comment Share on other sites More sharing options...

megawatt Posted December 5, 2011 Share Posted December 5, 2011 Just found this table:Chain Size ChartChain Size / Pitch /Inner Width - roller415 1/2 3/16420 1/2 1/4520 5/8 1/4525 5/8 5/16530 5/8 3/8630 3/4 3/8 So if you can accurately measure your chain, a 520 is 5/8" from one pin to the next and is 1/4" wide where it fits over the sprockets ie the sprochets are 1/4" thick . A 530 is also 5/8" pitch, but 3/8" wide. A 630 is 3/4" from pin to pin and is 3/8" wide. Quote Link to comment Share on other sites More sharing options...
