Rim problem
 

I just noticed cracks near several of the eyelettes on the drive side of my Salsa Delgado rims. I went online and can't find anyone who has 700c 36h Delgados available and it appears that Salsa no longer makes them, or rims for that matter. I went to the Salsa site and found nothing for rims at all. I also found several references online to other people having problems with Salsa Delgado rims. Did Salsa get out of the rim business? I've only had these rims for a couple of years, any chance of there being warranty for such a problem? Should I be concerned about the front rim which is showing no problems?

You will soon need a new rim or complete wheel on the rear. The front rim may last a long time if properly maintained.
