In the can't hurt to try category... I just got back from the Denver O store with a brand new set of Black R1 rubber (in a OLD box). I noticed that someone was selling some on fleaBay and that they had a receipt in the pic (carefully covering some details.. like price) but I could see it was from an O store and it was this year. So I gave it a shot and a local store had 1 left in stock (tried both Denver O's and the Vault). Totally worth the drive for $9.00 part.
