Seat looks way too high.
Skinsuit? Wheels?

Turtle your head. It's sitting way to high.

Seat looks a bit high. Sink your head into your shoulders.

You need a whole new TT bike.

Buy a C'Dale TT. It will MAKE you have the perfect position. Truth.
Looks like you could go forward with the saddle and lower in the front. Shrug your shoulders so your head is out of the wind too.
something is running down your leg ... and your saddle looks too high.
I think your bars could go down another centimeter. I don't don't think I would say that your seat is to high just by that picture.

Why does everyone think his saddle is too high? Looks about right to me.

I wouldn't say way too high, but it could come down a cm or two. It's not like he's locking out his legs. If it's comfortable, it's not necessary to change it.

leg looks too straight at the extension of the pedal stroke (i.e. too straight a leg angle at the knee).
a long time bike fitter I know likes to see a 30 deg angle in the leg at the bottom of the pedal stroke (as a starting point). I cant find my protractor, but Brian's looks to be less than that.

30deg relative to what? In the picture the angle between the femur and the tibia is nearly 180deg.
I would also say the saddle looks to high as the OP is nearly locking out his leg at the bottom of the stroke, but his heel is still well above a plane that is parallel to ground going through the pedal spindle.

I cannot give you useful information with that pic angle.
Overall it is pretty good. You are in the ball park and to get anything more useful you would have to see someone in person.

I'm no TTer but I've fitted some guys (successfully) for TTs.
I'd try some extreme lowering and see how your body deals with it. I'm talking 4-5 inches lower on the elbows, i.e the bottom of your elbows should be just above the top of the top tube. Right now you have a headset, stem, spacers, etc etc between your elbow and the top tube.
You'll find it easier to get to that position by rotating your pelvis forward, that means moving your saddle forward and possibly up (to maintain saddle-pedal distance, or saddle-BB distance if you want to be consistent with measurements for given pedals). Rotating your pelvis forward will get you lower by inches up front without having to deal with flexibility etc.
Unless you're in a "super hard effort" position in that pic, i.e. unusual to be in it for a long time, I'd move the saddle forward. You should be on the saddle, not on the tip, for regular use. Then you have room to slide forward when you're going harder.
See if you can't find a Look Ergo stem (borrow or whatever). You'll be able to mount the bar almost directly in front of the head tube, i.e. as low as the Ergo stem goes, then use the aero bars to adjust reach.
Your saddle may be a bit high but that's kind of individual. You should have seen guys like Bernard Hinault when they TTed - his seat was so high his hips rocked like no tomorrow and he'd slay all in big TTs that make today's TTs seem like limp pansy efforts - specifically the 87 km TT where he rocked the field in the Tour, including guys like Lemond (2nd), Roche (3rd), and any other alleged TT rider around. I tend to go higher than most with saddles, but not so high that hips start rocking.
good luck and have fun with the experimenting,

Yeah and I on the other hand am thinking of guys like Seán Kelly who was so scrunched up on a bicycle that it's no wonder people started upping saddle heights.

You won't get any real answers until the third thread.

Thanks so far. I will try your suggestions. The exception being that I can't move the saddle any further forward and still be legal.

Move everything down. Top tube, bars, butt, back, head. More the bars a little lower than everything else.
