Yeah apparently they are 7.5lbs for the set, which doesn't sound too horrible to me since I already am weighed down by a 2008 P1 Chromoly Framed beast. I was planning on building a beefy set of wheels to take some punishment anyway. The guy in that forum page said he ran them with out the plastic bit and they still rocked out on downhills and big drops. Oh SandPine I believe there is a ridge for the rim but that one guy removed the plastic bit to make it easier to seat a tire since I guess it is kinda tight. Oh Darrinw2001 thanks for the link for ediscountbike.com, $160 is kinda compelling...I might just get them to see how they roll. What you guys think worth a try?
