|Critique my position- Road/Tri||js5280|

|Did some seat/post swapping here recently including going to a forward seatpost to improve my position for triathlons. I've never received any formal fitting advice in person and was also curious to the effects the forward seatpost would have. I put the bike on the trainer and got out the camera to take a look. I have a number of pictures in each position (hood, drops, and aerobars) but these were the best and also the cranks are pretty close to the 12 and 6 o'clock position which seem to be the most telling. The hood and drop photos were taken with my normal seatpost, actually a setback, and the aerobars is with a setforward post. Also the seat height is the same for all the shots the photos were taken while pedaling, they're not posed. I have my own critique written up and wanted to get other's unbiased opinions to see how well I judged my position. Thanks in advance for your help!
On the hoods, setback seatpost, my normal road position
In the drops, setback seatpost, my normal road position
On the aerobars, setforward seatpost, triathlon position

|you saddle height could be a touch high...it is not too-high, it could be that your most comfortable a effecent saddle height it where you have it set.
I at least bring the clip up to 0 degrees, it looks like it is pointed down. I like 10 degrees myself, but 0 is considered the most aero. (I can pull harder on rolling hills with 10-degrees, and my wrists don't cramp up.)
Your back is alittle curved in the aero position. If it is comfotable to get your stem lower you would flatten out your back...and get you alittle faster. Making an effort to straight your back works too, but the handle possition might hamper you from doing that. I would just try out on a short ride swapping the spacers and stem around, this should get you 2-3 cm lower.
A forward lean seat post rotates the whole set up on your bike forward. Useing a plumb-bob to adjust you knee over your peddle axels is tossed out the window because your whole possition on the bike is forward. That is why I would try lowering the stem.
This is all a big game though, everyone is different and trial and error work the best...but for the most part, get your back a flat as possible, get your body as narrow as possible.

|Looks fine. I would bend more the elbows when on the drops.|

|You are far too close to the fireplace and could melt your tires if you arent careful. Are those 650's? If not, this picture just looks weird to me.
Personally, I would expect to see a bit more arm bend while in the drops, but others have mentioned, it is what is comfortable. An extra cm or so on your stem "may" help flatten you out a bit, and make you more in line with the whole "shouldn't be able to see front hub while in drops" as it is obscured by handlebars, but ultimately these are just rules of thumb, so to speak.

Go to Borders or something and read the fit section...otherwise it is a very technical book more suited to the 30+ hour a week professional. I pick up a copy on half.com for real cheap. Best info I have found on bike position.

Saddle too high, especially in tri setup;
And either too much reach and/or too much drop in all positions
*Possibly worth what you paid for them
