Yep yep, that's a Syntace W30 rim. Unexpected, but it might have just been a poor application for the rim, although I'm not usually that hard on equipment, they are a bit thinner and lighter built rim, more in line with a marathon XC type wheel.
In any case, the EX471's are tried, tested and trusted, I have put a set through their paces on my Stumpy for the past year and a half and they haven't even needed adjustment.
Also, non-asymetrical (double negative, yeww), so I can build my proper ZERO dish rim onto my SS hub and be happy about it.
EDIT:
I thought I'd show the wear of the Continental Black Chilli, ProTection compound after 600km.

I've been pretty impressed with the Conti's in general. They will mount without sealant, although the sidewalls are porous from factory, they wont stay inflated without its addition, they don't bleed out any of those holes though, they've survived the Alice Rocks without issue, other than one incident of the MKII deflating without explanation and not holding air when topped up at the bike shop...only to inflate the next morning and behave perfectly ever since.
Updates have been slow as I haven't been able to ride much in the past few weeks due to some personal matters keeping me around home. Mainly just been doing gym/yoga/weights, in the time off. Hoping things will normalise again soon and I can get back out onto the dirt.
