An unpleasent phantom shift this morning led me to the discovery that my chain had developed splits in the sideplates, propagating from the holes into which the pins are pressed. There are 8 separate places where these cracks have formed. The chain in question is an inexpensive SRAM PC38 that has seen about 2 years use, and was just ready for replacment, judging from wear (length measurement). I had similar issues recently with a PC48 chain. Has anyone else observed this problem with lower grade SRAM chains?
I'm usually careful about gearshifts, cross-chaining etcetera. and keep chains well cleaned and lubricated, so I would venture that the damage has not been caused by abuse or negligance
