So I think I am going to get the rear tire too. I'm pretty sure my rear hub on my Allez is about to die, judging by the terrible noises coming from it.i thought it might have been the rubber piece by the hub, but I pulled it back on the ride home tonight, and the hub still sound like death. I also tried lube, but didn't seem to help. So looks like I'll be on the hybrid the rest of the week as I don't want to have a wheel seize up on me during a commute.
