Hi, my name is Dean this imy first posting although I have used this forum for a couple of years helping me dcide on purchases, sizing, and other matters related to cycling. I am 55 years old and have been road cycling for 33 years. Some years are more serious than others. I had to cut back on running about 4 years ago and have logged 2500-3000 miles a year since then. My current bike is an 09 Specialized Roubaix Expert 54cm. I had a very difficult time deciding this and a Trek Madone 5.2 and went from a 56cm. Cannodale to a 54. I recieved a great deal information from this forum about both matters and am very happy with the decision I made. My girl friend and I are going to France in July to catch a couple legs of the tour and I hope to find some helpful experience on this topic too.
