Yep. And as a relatively new rider, be aware that the optimum position for you is going to change as you ride more. The low aero position that looks completely unobtainable now may become second nature in a season or two.

Also, every fitter has his/her biases and approaches. Plus we sometimes don't fit in the box that our outward body appearance suggests. Be aware of all of this. And - practice observing your body. If a fitter's advice seems just plain wrong, consider another. But keep an open mind. To go fast requires getting your body to get used to doing things that aren't natural to many of us at the outset.

This is a journey. Take it with eyes open. There will be bumps. I recommend hanging with and riding with good riders, perhaps ex-racers. They may well see things out on the road that can be huge improvements for you. (I bought the last year's race bike in the basement of the shop I worked my second year of racing because the mechanic recommended it to me. That bike fit! Second ride I took 2 minutes off my training route riding easy!)

Good luck! And don't forget to enjoy this!
