Quick shout out to the folks at E13. I managed to kill one of their carbon rims on my YT Capra CF Pro in Downieville on a perfectly placed rock fin. Rims have a lifetime guarantee and I had an entire new wheel in my hands the day after I contacted them. Can't thank them enough. Those wheels are tough, 10 days at Whistler, lots of Tahoe and Norhtstar riding didn't hurt them, just an unlucky landing spot right on a rock did it in.
