Bump

To my (non-professional) eye, you look good in the drops and it seems like you can probably get lower when on the hoods. Your back is nicely flat in both positions, telling me that you aren't straining when lower. I would try bending your elbows more when in the hoods to move toward forearms that are parallel to the ground. Neck strain will tell you if you are pushing up against the limit of your flexibility.

Not a pro here and my old laptop gives lousy quality on your legs, but it looks nice on the TT. (In no way am I going to speculate on the road bike.) But, given the all the talk here about upturned extensions.......and Andrew Coggans pictures in that same thread...?
And, is it comfortable (it appears so). If it's not, your going to lose power or aerodynamics getting up and down a lot.

Take everything I say with a grain of salt. I know nothing.

You look comfortable and smooth to me. Are you running short cranks? If not, then I'm impressed with how little leg motion you need to get the pedals around. You appear to be tall, but not that tall.

A couple things: On the TT bike you are going to wear a helmet, so wear it in the video and look as you would while riding. It's an important part of your position. Some things I'd experiment with are elbows closer and angled extensions. Also try getting lower in the front since it appears that you could pretty easily.

On the road bike I'd make sure you have a comfortable position that gives you a flat back.

175s on the TT bike and 170s on the road bike and I'm 6ft 3 192cm

I think if I pull the pads inwards or angle them up that will pull me forward a bit more making me lower but then I could have saddle issues due to a different contact point or my butt will stay in place and my arms maybe angled more

drop spacers, listen to rruff.

Ok this is where I at now I lowered the saddle 15mm it was a bit too high my hamstrings were feeling it in high intensity

I have angled the elbow pads up 7degrees and the tri bars are now narrow as possible
Btw thats an adjustable stem

TT fit looks outstanding to my eyes in a 60 second skim of the video and the picture with the changes you've made. From the video my only comment was to maybe consider ski-bends. Your wrist position looked a bit uncomfortable, but if that's all I have to say I'm really just splitting hairs.

Keep your head low and race with confidence.

I'd work on dropping the bars quite a lot, and the saddle a little more. Gradual. Since you are doing TTs it's all W/CdA. You probably have a ways to go before you optimize that ratio.

I'm guessing you don't have a PM?

I'm testing the position on track tomorrow. My concern is that if I go lower ill have to use even more neck extension to look upwards

No, dont have a PM riding on feel makes alot more fun

On the TT my only feedback is see if you can angle the aerobar up. I have done this recently and my comfort went way up and my speed at same wattage went up about .3-.5 MPH over a known course. I did have to raise my arm pads a bit due to the angle affectively dropping me a bit.

I ride on feel too, but the PM is very valuable for field testing.

Neck craning isn't fun, but we manage by turtling and peering though the eyebrows. The courses I'm on aren't technical so I don't look fully up very often.

Do you think going lower will get me that srugg position head between shoulders?

It helps me pull my shoulders in and down, and keep a good torso angle, if there is a lot of drop. If I relax the shoulders then my torso drops down and it's more uncomfortable.

Everybody is different. If that doesn't work for you, there are other things you can try. But getting low and narrow however you can is a good starting point. Jim@ERO says a 15deg forearm angle is a good start as well.

Quick question as ive lowered the saddle 15mm if i I lower the spacer by 15m would I keep the exact angles?

Like this video it seems im bit wider/bigger in the chest compared to the lowered 15mm saddle picture

I also think i need put the pads towards me more and the extensions out a bit as my wrist get crunched up a bit

Does anyone happen to have a program that can measure my leg angle, foot angle and torso and arm angle?

Lowering the front the same as the back should be close to the same angles, yes. But I think you could go a lot lower in front.

If you want to go fast, lower your saddle too, but take that one slow and carefully. Your legs are very unaero cylinders running broadside to the wind. Don't worry about the angles.

OK I'll need to look for some 1cm x 4 spacers to replace That 4cm aero block spacer I will try get a video up tomorrow with the 4cm spacer removed to see what and feels like. What do you mean by legs are unaero too?

Legs contribute a lot of your total aero drag. You are better off erring on the low side for saddle height. Less projected area, "cylinders" at an angle rather than perpendicular, feet more level and toes not so pointed down.

Maximize W/CdA. After adaptation... that's the tricky part. If you road race with climbing though, you won't want to sacrifice power to get more aero.

20mm lower front end




40mm lower front end (feel like im falling forward)

Sam,

I think if you tilt your aero bars up closer to the 15* up that rruff and Jim M. have mentioned you will likely feel a lot less like you're falling forward. Your position is definitely looking better.

Genetics load the gun, lifestyle pulls the trigger.

My torso angle is 8 degrees the one with the hat on and 9 degrees with 20mm spacers If i tilt the bars up 15degree (another 7degree up from where they are) I'm sure ill be close to a 0 degree torso angle to the ground

Depending on the geometry of your pads, you may well need to add back a spacer if you tilt the aero bars up. If you're happy with your torso angle than this is likely the case. Perhaps just a 1/2cm would even do the trick.
