I know there is a lot of info out there hating on DNA's spoke wheels so I figured I should share my experience with them so far. I've had them about 2 months now and have had ZERO issues with them. They came to my house in about 5 weeks which obviously is a long time but I was told before hand that it would take that long so no surprise. They showed up put together nicely with no flaws. They had tons of sealant around the wheel to seal the spokes so you didn't have to run tubes (I didn't). The only thing that sucked with them is all the sealant made it pretty hard to stretch the tire around the wheel because let it fall in the drop center. They balanced out with a lot less weight than expected considering how much they weight (1oz on the front and 1.5oz on the rear I think). I put a Metzler 880 on the rear and an Avon AM41 90-21 on the front because the Metz was back ordered. My bike seems to ride smoother with them which is probably due to the weight. All those geezers that say 21's ruin the ride of the bike are just being grouchy and stuck in their ways lol because even with this thin 90-21 my bike feels great. I guess the only bad I would have to say about them is that they are a pain in the ass to clean and they are kind of heavy. Consider me a satisfied customer!
