On the CSR-E you get some kind of rubber on it which looks all right but I've seen videos on youtube of used rims where the rubber was halfway gone from the wheel. A couple of weeks of heavy wear seems to be enough to destroy it..
Yeah, I saw those videos too and I couldn't believe it.
You have to wonder about ways those people use that wheels.
I have my CSRE probably longer than anyone else - I was in the CSRE beta-testing and have been granted with one of the first units ever produced (it bears #00003 numbering). I am using that wheel for more then a year now, almost consecutively for 4-days-in-a-week in long multi-hour sessions. And the rim is still like it was when new. Only thing I take care about are palm-sweat marks that i gently rub from alcantara-parts with small alcantara-care stone from time to time.
Almost 14 months later wheel is still top-notch, I really can't imagine what those people (not you Drugstore ) are doing while driving..
