I just didn't want you to think you were saving a watt but really losing one, and all the other out-front Garmin riders laughing at you behind your back. But they're thinking 1° or 2° and your 7 or 8 is a totally different picture, joke's on them now.

But having a computer is too valuable to give up regardless of what the answer is. Especially with maps, I like riding in different places.

A stealth mini-faring to capture those mini-watts! Awesome!

Lighter = faster.

Surely the most important thing is to make the text on your Garmin incredibly small. That way, every time you read your power output, you have to bend over till your face is 3 inches from the device which will make you more aero.

An awful thought: if the Garmin that's tilted up at between 1 and 2 degrees is a parachute, what about the saddle?? Is my 1° saddle tilt also turning it into a parachute? Do we have to level everything on the bike now?

It think it is better for two reasons.
-If you want to look at it there is less head movement and that cost AERO.
-If it is close to the stem it helps shield the stem, vs on top which is mostly catching air and your body is too far back to draft that.

I like the out front mount (but not enough to spring for more than the Sram one)
because it's easier to see, and the angle can be adjusted to get rid of the sun glare when it happens.
Can't measure the parachute effect, because one position had too much glare to read the wattage.
I also don't feel so confident in the rubber bands used in the standard mount.
Bottom line, 'tho- is setting it up the way the cool guys do....

I believe there is more drag going on around the handlebars than we usually credit it, and I suspect that the stem mount, in spite of the optics adds little if any additional drag due to the turbulence. With a particularly aero handlebar and flipped stem it may be a different story.
I've actually been mulling over a side-mount on the stem, to get it behind the bars, but haven't yet because of this uncertainty. This is a trivial enough concern to warrant some testing IMO.
