Bike Position Critique

its a bit hard to tell, but I might move your seat up, and forward a bit.

First, love the wheel cover.

As for the position, I've seen worse. Even on some very seasoned riders. If you're comfortable and can keep the position as much as you say, you're 99% of the way there.

Arm angle relative to torso looks good, but I know my lower arms would be screaming at me right quick if I had to hold the extensions like that for long. Might look into some ski bend extensions to relieve some arm tension.

Head position... Looks like you're still carrying some tension in the upper back, which is keeping the spine high, and thus your head. You're "turtling" pretty well given all that, so if you can relax the upper back some, let the spine drop downward between the shoulder blades, you could get your head a bit lower without affecting your ability to see up the road.

Lastly, I'd say try dropping a spacer in front, and if that doesn't cause any back bowing, stay there. If so, try rotating the whole position forward around the BB.

This pic is dark, but I spent a fair amount of time and money on this fit for my kid.  Hopefully it helps you get some ideas.  He can stay in this position forever and generates lots of power.  You can easily see the difference in his back position and yours.  You can also see that his torso is fully rested on his arms and that his upper arm and forearm are nearly, if not, 90 degrees. Also notice his hands relative to his arms because of the ski bend extensions. 

I think you can drop your arm pads and/or spacers quite a bit. (look where his elbows are relative to his hips compared to yours)  After you do that you may need to move your seat forward.  Basically you will be moving around the BB like was suggested.

It doesn't really work like the lines you have drawn there when comparing those two positions.  Your picture is not at a right angle.  He is 6'4" and his bike is a 58. You are about 5 inches shorter and your bike is smaller.  The distance at which the pictures were taken is not the same.....and on and on.  All that picture can do is give you a relative idea of where you should be trying to get to. 

I can't tell because the picture is angled, but perhaps a longer stem would help.  Again, I can't tell because I can't tell how forward you actually are.  I do agree that you are a bit tight, but lowering your arm pads/removing spacers out will help that to a degree, but it's hard to say how much.  If you put your bike on a trainer and take a picture or two at right angles you can get some help from this board.  There are plenty of people here who understand bike fit.  If you REALLY want to get it right......find a good professional fitter in your area and get it dialed in.

Well......I'll have you know.....  I FINALLY convinced the kid to ditch his "aero bottle" and straw......but he hates you.

Dimension and Profile make stems with some pretty steep angles -- 25 degrees or more -- that will allow you to get MUCH lower if that's preferred.

And I agree, seat is high. Your hammies will thank you.

I've also liked the Specialized stems. They're fixed, but have shims that allow for a range of 8* in 2* increments. Some versions can reach down to -28*.
