I installed a new front derailleur cable, internal routed. Connected to the front derailleur, but now with the tension on the cable, when I turn it moves the front derailleur. What did I do wrong?
Tri-Bars – Front derailleur moves when I turn.

Your cable housing is getting pulled somewhere. I’d guess it’s too short or not routed exactly the same as it was before.
Cable housing is too short.
Housing is either too short or tangled on something

Which aerobars are these on your bike?
Maybe you installed the cable with the shifter already in the big ring position?
Check the route of the cable. Something isn’t right there.Â
But in the real world you never turn like that anyway so it’s not a massive problem if you’re want to try a ride.Â
Hideous cable routing. As I recall, it’s all over the place by the bars. Then, it dives into the top tube, heads forward into the steerer tube before turning back again down the down tube to the bb.
Not seen resistance like this since Star Wars!
I would run those cables out the back of your tri bars instead.
At the very least, your front derailleur is cutting across the centre point and then back around to the entry hole in the frame.
An immediate fix is to not route the cable to the right but, like I said, route it through the bars.
What a mess
You’re never gonna turn that much on a TT bike so who cares
It’s feature, not a bug.
But yeah, housing is to short or stuck somewhere
