I think they are putting a more traditional wheel on the 7500 in 2010 not the paried spoke ones. The Bontrager wheels arent bad for what they are and the 5 year waranty isnt bad either. Buy the bike ride teh snot out of it if you have wheel problems do the waranty return thing and get anoter set.

So who knows maybe when and if the old ones have a problem they will replace them with the new ones.
Not all of them go bad I have see wheels ridden by heavier people that are still fine.
