Right after reading a little more into particular parts of fits on roadies and forming a opinion of who it benefits most cyclingtipsblog have posted a pretty decent article (as always) pretty much confirming what i have gathered myself. Here are his conclusions. I like the fact that he admits to being vain. I think there is room to be a little vain as long as you ride your bike to back it up.
1. Beginners who aren’t familiar with how a bike should fit and feel. An expert consultation will also give you a good reference point of how comfortable a bike should fit going forward.
2. People who can’t get comfortable on their current setup or have nagging injuries. A good bike fitting specialist will know how to translate your discomforts into a better setup. Nothing will turn-off someone from cycling quicker than an uncomfortable ride.
3. Competitive cyclists who are looking for marginal gains. There’s no doubt that more power can result from tweaking your bike position, however I don’t necessarily feel this is the low hanging fruit that should be considered right away if you’re not winning races.
