This year, I have been on a quest to be more efficient and make my bike as light as possible while retaining its practicality. So far I have achieved the second goal of a ridable 12.3 lbs machine. As part of the first goal, I picked up some D2 custom shoes with a lower stack height, changed to a lower stack height pedal system, and changed my cranks to a narrower Q factor. The last part of the goal to be more efficient was to get another fit to see how all these other component changes altered what was going on with my body on the bike. It was time to tune up everything with a visit to Todd Carver of Retul.

Go to the Source
Todd is well know in international fitting circles.
If you want to learn more about Retul here are some starter links:
The inside tri videos walk you through the three step of a Retul fit.

The Method
Here is the quick and dirty- basically they stick 16 little velcro dots on different parts of your body, then affix a wire between these dots. A "camera" read the LED dots in 3D and measures the distances, angles, etc for a variety of rider measurements and displays them in real time on a stick figure on the computer. If you want a more technical description, check out some of the above websites.

Having been fit by Todd before, I didnt need to go through the whole process again. I scheduled my visit to the local Boulder Retul studio to coincide with a few weeks after the arrival of my new shoes to allow for some adaptation and changes to the foot bed if needed.

What is different about the Retul system is that it is dynamic, meaning you are measured at a multitude of different points while applying real world power to the pedals, not stopped just a plumb bob stopped in time. Another advancement is that a Retul fit produced quantifiable results for easy comparisons of the before and after adjustment fits. For example, if you change your saddle height only (as we did with me), it will impact your knee over pedal spindle, back angle, arm angle etc. Todd was able to isolate what looked good and what could be tweeked better in my position fairly quickly. In that sense, once an operator is trained on the system and the basic fit parameters for the different measurements, the fit system is user friendly for the operator and faster for the person being fit. The swivel floor was great for measuring the difference between both sides of my body.

End Result
Although I have yet to put some real mileage on the new fit (we lowered my saddle quite a bit), I am pleased with the new found comfort and promise of better power. Todd has an open door policy for making sure his clients are happy after the fit and to make adjustments as needed. Hence, this fit for me.
The system is way cool and would be a great addition to any shop wanting to give their customers some tangible evidence that the fit offered is the best for custom fit for them. To me, the Retul fit took away a lot of the hocus pocus that goes into other "fits" that I previously tried from other very reputable local "fitters."

I agree that a good fit is VERY important, but to go faster, you need to ride more too. A lighter bike is neat, but might only save fractions of a second over several miles.
Great to hear you've got a great fit now! :D
