Umm, of course? The I9 hub is proprietary, meaning that it can only be laced with I9 spokes as well. They do make a conventional hubset as well, but it's easy to tell from the picture that these are the more common center pull I9 wheels.

Wow. Your offer inspires great confidence that you'll actually pay an appropriate price.

That doesn't make it right to put it in the wrong section just because it gets traffic. When I'm shopping for a DH bike, I don't want to see a motorized anything. I'm pretty sure I'm not alone...
