Two words of caution about the Retul. I think it's a great system, and it is only effective if you answer questions about your riding style and goals honestly. All outcomes from the computer measurements fall within ranges of what are considered OK or out of the norm. So, the norms shift depending on the type of riding and riding goals you have. So, if you get a Retul fitting be brutally honest in your answers. Second, I have seen Retul fittings done by four different people and two of them seemed much less skilled than the others. I suppose it's like anything. Two people can be trained to do the same thing and one might do it better than the other. I was fortunate to have someone do the fitting who seemed very competent and knowledgeable. Hence, if you invest (and it is an investment) in this fitting consider asking how many fittings the person has done and see if you can talk to a few of his or her customers to find out how happy they were with the fitting. Personally, I asked what other fitting system the person was trained to use and was pleasantly surprised to learn that he had been trained in two other systems - The Fit Kit and Specialized BG Fit System (I saw the certification documents. So, I knew it to be true). I think this helps and makes for a better Retul fitting. Just my two cents.
