I came into 'bentdom with the impression that a chain might last 3000 miles with care. I also
thought that a KMC chain was a piece of **** since it was not Shimano or SRAM/Sachs. The OEM KMC
chain that came on my '99 RANS Stratus had to be the lowest of the low in chain. At about 3000 miles
I bought a 'good' chain (SRAM) with the intention of replacing the KMC 'piece of junk' on my
Stratus. On checking I saw the KMC chain had usable life left in it and others pointed out that the
longer chain path on a bent afforded a longer lifespan than might be expected on a DF. So, I left it
on. And on and on. I did replace it 8000 miles but it could have lasted a little longer.
I do agree that the best replacement chain is SRAM. I like the Quick link. Shimano on the other hand
does not recommend the use of quick links and requires special pins. These pins are expensive (~$1)
when compared to the included SRAM Link (free).
Since 9-speed chains are narrower and require closer tolerances, I wonder if all 9 spd. chain
problems might be related to improperly installed or reused link pins. All manufacturers caution
against reusing the old link pins.
