    Any difference between the SRAM 8sp chains?

    I eat through my 890is, replacing them every 3 months (2,000 miles).
    Before I order more of these babies ($25 each...), I wonder if I should downgrade to 870 or even 850.

    Has anyone noticed any difference in peformace, weight, longetivity, durablity within the SRAM 8 family?

    Thanks for wasting your time...

    As climber999 said the only difference between 890, 870 and 850 is the plating, they are all rated with the same minimal tensile strength. If I might ask, what are you doing to break these chains? Are you Sampson or do you ride 100 miles a day?

    Thanks Brad,

    I ride my Monstercross 30 to 40 miles 4 to 5 times a week. Every couple of weeks I go for a longer one -- 70 or 90 miles.
    The gear inch ratio is high (70, which is 42/16), so I guess every three months they stretch and I cannot use the power link to open up the chain for cleaning, which gets me frustrated. Then I put a new chain on...

    Any idea about the plating? Is that just to prevent rust, or also more friendly to the cog/chain ring?
