I'd troll craigslist and get a replacement Aksium. I see them all the time for sale for very reasonable prices. The Aksium is the only Mavic wheel I'd own because they are cheap enough to be disposable, yet they are quite reliable. Consider this: They want $200, which is more than the whole wheelset is worth, to fix your front Aksium. How much worse is it going to be if your $500 Ksyrium gets trashed?
