Chain advise

[rogerdias]

My mtb chain is stretch but it does not slip yet,some say ride till it does then chain or should I rather chain now?if I put new chain will it damage the cassete?

[dalem44]

Rather change the chain before it slips. A worn chain will damage the cassette and chainrings. If your chain is changed at regular intervals, you will prolong the lifespan of your drivetrain

You don't say if its a 10speed, 11 speed or speed drivetrain.

 

If 10 or 11 speed

If the chain is "stretched" beyond 0.75% wear then rather run it and the cassette into the ground as its very likely that you damaged the cassette already. If its less than 0.75% but more than 0.6% wear then just replace the chain ASAP.

 

If 12speed:

If the draivetrain is a SRAM Eagle GX, XO1 or XX1  and the chain is worn beyond 0.5% replace the chain and cassette. 

If the chain is worn to <0.5% replace just the chain with a XO1 or XX1 chain.

 

 

PS: Buy yourself a chain checker gauge Park Tool CC-4 is a great investment
