So I bought a road bike about three weeks ago to try to get some exercise and maybe work my way up to organized rides. I bought a 2008 Fuji Roubaix Pro immediately starting pounding on it. Within a week I had done a 21 mile ride, but then things went downhill. I got sick after a bonfire party and the Asthma decided to come back so I lost a week of riding to that. When I started riding again, the lungs would only let me go for 10 miles or so before they told me to go back home (its cold in the evening in Austin). Finally my lungs had gotten to the point were they were no complaining very much and yesterday I had to come back in after 12 miles due to a flat tire. I patched it up and headed out today, only to have it go flat on me again. So in the garage I put in a new tube, watched the Cowboy loose to the Steelers and headed out again. Going 30MPH down a hill the rear tire blew again! When I got back there was a chunk missing, but it looks like its in the rim facing part of the tube.
Am I doing something wrong? This is the first time I changed a road tire, but I have done mountain bike tires for years. I'm 6' 0" and weigh 238lbs. I aired up the tubes to around 95PSI before I went out.... Is there any trick to changing road tires and rims that I'm not aware of? Also there is a little side wall damage new tire. Should I replat the Continental Sport 23Cs?
