Ok I've tried the search but found only questions with no real answers. Thos of WITH the DNA 52 mammoth spoke wheels...how do you like them now? Most of the posts about them were awhile ago. Other sites just have people whining about their problems. I oredered a 21" front for my RK. Some people have gone with tubes even though they're a tubeless wheel,some have gone w/out. Can I get some FRESH reviews please?Thanks!
