I have a SRAM PC-69 on my road bike. Last week I cleaned it really good, letting it soak a few days in some degreaser, then scrubbing it really good and letting it sit for a few more days to dry. I checked it over really good afterward and noticed a tiny hairline crack in one of the links. The crack starts where one of the pins are and radiates toward the top edge of the link. Don't have a pic of it, but I think you get the gist.
Well today while I was getting my tire retrued at the LBS, I was standing there next to the wrench talking with him when I noticed that the crack was now Huge. It's got to be at least 2mm to 3mm across. So it definitely needs to be fixed now.
What I'm wondering is. I have my old SRAM PC-99 chain that I saved. It had several (3 or 4) of those same hairline cracks so I replaced it with a PC-69. Can I take one of the good links from my old PC-99 and replace that bad link in the PC-99?
Or maybe I could use the powerlink from the PC-99 somehow.
Any suggestions are welcome. Thanks
