The 2nd day I road this new tire it malfunctioned. A 3" sidewall seperation from the bead. The tire blew going downhill at 20+ MPH, and I thought a gun had gone off. I was on my front wheel rim immediately. My bike started floating and I went down. The worst Bike Crash of my life. Ambulance to the Emergency Room with broken collar bone and multiple body injuries. I have done 6 Ironman races but this tops everything.It will take years to recover. It appears that Ritchey has defective TOM SLICKS floating around. Please email me so we can save other athleetes.
