|Fit kit with a power output?||Chicago_Steve|

|I visited a LBS that I don't normally frequent over the weekend and the guy was showing me a custom setup they designed for fitting people.
They had a Serotta Size Cycle with a power meter feeding into a computer (I think it was a Power Tap). The guy explained that their fitter could then adjust your position and look at your power output to try and find the best combination of fit/power. The fitting was pretty spendy ($125 for a 3 hour session) but the idea of seeing how adjustments to reach, seatpost height, and other factors contribute to power output was pretty intriguing. They even had a couple of referral letters from guys that saw personal bests after getting fitted in this manner.
Anyone get fitted like this before? Hype or worth it?

|Sounds interesting. I think that the $125 for 3 hours is not exorbitant, either, if it also includes cleat positioning.|

|at Wheat Ridge Cyclery here in Denver area.
I found it to be very, very interesting. For example, on saddle-to-bar drop, there was a point at which my power stopped increasing and starting decreasing (whether bars coming too high or going too low). Interesting to think that the "sweet spot" for bar height may influence more than comfort.
Here, the device also showed my disparity in pedaling strength from right to left (left leg is the injured one).

|The idea is interesting, but there's a pretty major flaw in the logic. Power is only one side of the equation - aerodynamics is the other. A position that makes you 10% more powerful, but makes you 25% less aerodynamic isn't doing you any favors. This isn't to say that a little bit of knowledge can't make up for this, but just using the raw numbers generated from a size-cycle is probably not the most reasonable way to choose a fit.|

|My concern would be that my most powerful position might not be my most comfortable position. What good would I be if I was fast but couldn't stand riding in the same position for many miles...
Interestingly, the referral letters I mentioned were both from triathlete customers. Usually they're the guys most concerned with aerodynamic positioning on the bike!
