I called SRAM directly a year ago with Elixir problems. Guy answered (don't remember name) right away, was really helpful, and helped solve the problem. So my one and only call to them was very positive.
I've called several times (mechanic at a LBS) and have had nothing but outstanding customer service from them.
Even had a customer call them about a Juicy 7 corrosion issue on the master cylinder. They told the customer to stop in at their LBS (me) and have them handle the warranty. Told my customer that they would replace BOTH brake sets. Sure enough they did when I called them about it.
My experiences have all been as good as frdfandc and then some, however I am also a shop mechanic. I even called them to get some parts for my own very old BB7 calipers I was rebuilding a few weeks back, only to have them send a whole new BB7 because they didnt have parts for my really old calipers. I really didnt expect that much. Sram service is enough of a selling point that I am torn as to my next fork purchase, Sram or Fox.i have also found that when they send stuff out they do it quickly with out delay.
