Hello...I have been riding for almost a full year. Started out as a C rider (14-16mph avg) and have progressed into an A- rider (18-20mph avg). I use a small shop who happens to be a dealer for my bike, but his fitting techniques are very basic, which I am sure is fine for most riders. I know there is a lot more science to bike fitting these days. I have heard about the Trek Precision Fit, Retul fitting, etc...

Where I live has a very good combination of flat sections, short steep hills, long butt kicking climbs....so, pretty much all types of terrain.

So...2 questions:

1. Do these high-tech fittings offer any more benefit than the basic fitting?
2. If so, which is preferred?
