32. What are you up to? lol.
No problem. Bear in mind that's a steel rim and weighs 35 lbs. with a TW tire mounted, if weight's a factor on your project.
Black rims have come and gone a couple of times over the years and I'm not sure which.
Maybe Sinophilia or someone else can fill you in on that. My '03 parts bike had them.
From what I can find, the black are the more common rim.
Is there any difference between the 2011 rim and the 2006 rims in terms of technical properties (size, make, spoke count, anything other than cosmetic?) The part numbers are different, but I'm assuming its just the color changing.
Sinophilia, where are you
