SHIMANO BIKE FIT Seen at NAHBS

SHIMANO BIKE FIT Seen at NAHBS
Shimano to fit a rider to a bike has that person ride a special bicycle
Has you ride it measures your power output at a steady rpm
and has you ride (without getting off) they vary the length of the cranks by hydraulics Raise and lower saddle Move saddle back and forth
Etc.
All while measuring your power output
when your maximum power output at a steady cadence is know (get this) they search their data base of all known bicycles from the majors bike manufactures and find one that fits per above criteria
wow that is being fitted correctly

I sent Dazza a few measurements that he needed and some info on my (then) current set up, he made a few suggestions and that was it.

And......................the frame fitted (and still fits) like a glove

Sure......
But I wanna try shimanos way.
First with my bikes numbers plugged in and then optimized their way, and see how much power I've been wasting because it "felt" ok

Agreed.

Along those same lines, I wonder if a rider's "max power output for least effort input" geometry always matches his/her "kindest to the knees" geometry?

Guru has had similar in the market for a number of years

Very expensive for LBS to license the software

Does it also tell me which cereal (from all the major manufacturers) to eat based on a stool sample?

We are doomed.

The problem is that the position for optimal power out may not be same position as optimal comfort. There are a lot of interacting variables at play for power output over long durations that may not be measured and captured by this device.

+1. My initial thought, exactly.

And there is no way you could keep a steady output while all this is going on.
RPM, maybe. Power output, I don't think so.
Marketing at its finest.
Our bodies ability to adapt to variation in fit is almost seamless. I have never believed there is a 'perfect' fit for all scenarios on a bike. My position is different on bikes I use for different purposes, each having different priorities.

That and the muscles will be more likely to want to be in the position they are currently used to.

This sounds very similar to the Guru fit, which is what I did before I bought my C60 a few years ago. In my case the fitter made small adjustments, then we looked at power over a few minutes at a time. I also stretched and had a good warm up period. The screen showed power output independently for left and right cranks, and I think that it showed push/pull as well, but I might not be remembering correctly.

I am very happy with the results, but I don't think that power measurement is a replacement for a good fitter watching you on the bike.
