Road bike setup to optimise TT bike performance

I was wondering how I should set up my road bike to optimise my performance on a TT bike. I am not concerned at all about raw aerodynamics or speed whilst training on the road bike but more about things like muscle activation, power output, flexibility and other things that will improve my bike splits once I get back on my TT bike. Is there anything in particular I should change or read up about? I have a hunch that a road bike fit optimised for someone only riding road bikes makes some compromises for the triathlete.

(Due to my locale, I do most of my outside training on a heavy alloy road bike. I still log quite a few hours on the TT bike on the turbo trainer and when the weather improves.)

Not sure it makes a massive difference. But if I understand correctly, a properly set up non-UCI triathlon position can be very very close to your road bike position, only rotated several degrees clockwise about the bottom bracket. I would think that if you pay attention to hip angle and absolute distance from seat to bottom bracket then you are pretty much there. Probably more an issue for UCI-legal TTists, if an issue much at all.

All that I’ve done is match my hip angles on my bikes…tri, mtn and road
.

You should just ride your road bike and not worry about the set up/angles etc. It’s like a dog chasing it’s tail. You can go round and round with it and never get anywhere.

It’s been said often on here but bears repeating again:

It matters more that you ride a bike and less which bike you ride.
