Hi,
I am just curious what is the proper hand position on TT bike. I have Shimano 11-speed mechanical shifters (SL-BSR1).
Where exactly should I have my fingers? Thumb on the top? That’s fine when the shifters are straight. But when they are vertical its not possible.
Should I aim little bit back.
I like to know it before I will cut the carbon too far 
Thx in advance.
Slip a couple of rubber bands around the extensions. Keep your hand behind them while you ride. You can roll them back and forth while riding to find where would be the best place to cut the bars. Then just stick the shifters in the end.
It’s really a matter of personal preference.
I like to have my thumbs on top of the shifters, some people like them a little bit longer.

I already cut 5cm from the extensions.
Based on the picture from yesterday its obvious that my elbow is too far. (I will switch armrest 1,5cm back)
I also think my hand should be little bit further. or its fine like this?
I see you have the stupid Shiv extensions that don’t adjust. Specialized now make a simple set of collars that allow rotation and fore/aft adjustment of the bars. It looks like u need to shorten the bars a bit more. I would saw away knowing that you can throw those stupid bars in the trash if they don’t work
yeah, only adjustment available is saw I already cut seatpost twice per 5cm and the bar once per 5cm
i have to be sure so I will cut it by cm
and what about seat high? looks fine, don’t?
I like the shifters to be right in your hand so that you barely have to move your arm to shift. This will ‘encourage’ you to shift more often, which is a good thing.
The hand position relative to the shifters in your photo looks pretty good to me.
It looks a touch high to me, but it is hard to tell from a static picture. Ankle motion can change the knee angle. Have someone ride behind you and have them look to see if your hips rock side to side. That is a sure sign of too high. Soreness behind the knee is another indicator.
I would recommend a bike fit, but I haven’t personally found them very useful.
Yes, it’s all personal preference. Heck, I found I didn’t like my wrist angle using S bends and swapped out my OEM extensions for ski bends. I have small hands so I cut about 1" off the ends and may cut another 1/2" when I recable my shifters some time in April.
That is pretty much how I hold onto mine.
