chain stretch

Azz78

hi all
i have had my GT aggressor XCR 08 for 4 months, has a truvativ firex chainset, xt rear mech, deore cassette and hg73 chain. using the park tool chain checker the chain has stretched to the .75 mark. recommended chain replacement is 1000 miles i've only done 500 miles max of casual riding. i've had a few decent mtb this is the first 1 where i have had to change my chain so soon . i'm thinking its the chainset i've only used shimano in the past, what do you think ?

Could be a large number of factors, for example it has been a very wet summer which never helps longevity.

You could always get a SRAM chain and see how that holds up.

Main thing is to get the chain changed now before you wear out chainrings and cassette.
SRAM PC971 or 991 would be my reccomendation.Tredz seems to be the cheapest at the moment for SRAM chains.

I think the lifetimes they quote are for a perfect condition where the chain never encounters junk and is always perfectly lubed.

On road you can probably get close with a lot of maintenance but off-road you have no chance IMO.

Change it and be happy you caught it when you did, 4 months is not a bad lifetime in my experience.

i ordered a new chain befor i posted. i ordered a shimano hg93 though, i will try this chain if same thing happens i will get sram
another thing, when i 1st got the bike the chainset,chain,cassette did nt feel smooth i could feel the friction, new bikes do this i know but it still does it

They often settle down after a few rides (and the gears readjusted)
