How do you measure chain stretch?

[Guest]

My front 12 tooth cog is worn bad and I wanna see if its because I have a ****** front cog (Renthal) or if my chain is streched. My back sprocket looks good. If my chain is good Ill just put the stock 13t on for now but if its bad Ill replace both cogs and the chain. I have the manual but couldn't find anything on this. Thanks guys......

I believe you should buy all 3 new. You may not notice it to the naked eye but the chain and sprockets kind of blend with each other. If you put a new chain on with old sprockets or vice versa they will not mesh together the way a new set does and down the rode they will wear abnormally!

Well To measure stretch, you just whip it out and let it hang, and see if it can stretch out, the further it stretches, the better off you'll be
