After I purchased my first road bike, in 2011, I was having problems with pain is different places and wondered if I had made a wise purchase going from a hybrid to a road bike. I was 64 at the time. I was getting ready to ride my first MS-150 and knew that I could not do it with the bike the way it was and was seriously thinking of cancelling the ride. I read a lot of forum threads on bike fitting where there were a lot of people that told me to save my money on a pro fit and do it myself. That would have been great if I had known what it is I was suppose to do and how to do it. I also didn't want to screw around with it for several months in hope that I got done correctly. So, I began researching the different fitting systems and decided on doing a Retul fit. It cost me $250.00 for 4 different sessions and it was the best cycling investment I had ever made. I did the MS-150 the following month and didn't have any issues whatsoever and the pain I was experiencing prior to the fit, was gone. While there are other fitting systems out there, I found the Retul system to be the best for me.
