It sounds terrible! Must still be within warranty if it is an X.I thought i seen a thread but cannot find it.
Just picked this gem up used and makes scary noise from the rear hub
You should contact Specialized to find out if the warranty is transferable for your used bike purchase. I dont know if you'll have much luck after a problem has been found, but you never know. The worst they can say is no.I just got it today. It was shipped to me so rough shipping I guess.
What's the warranty on X?
