Definitly. I could feel the difference when I got my new bike and everything just right for me. It was great to have the right reach to the bars and length to the pedals. It was close to perfect when I left the LBS with it but I did adjust the seat just a bit after a ride or two. At that point the right bones seemed to hit the right points on the seat. I even marked the saddle height and position after that ride so if anything happens I can get it back to this point. lol
