I thought the housing had to push against the frame, then comes the cable.
But it sounds you're running the housing all the way to the FD.
Yes, I am running the housing all the way to the
R7000 FD. The cable housing is pushing against the FD stopper (as illustrated in the image documentation in my above post and my attached image here).
This is exactly the same principle as the Rear Derailleur, but the Rear Derailleur has a tension adjuster but works with similar principle; the housing is pushed against the RD cable housing stopper.
You just need to make sure to remove all the slack from the Front Derailleur cable before you tight it down.
Don't think too much about it. Just try it. It works guys!
This only works with Front Derailleur with a built in cable stopper like the Shimano 105 R7000 front derailleur.Excuse my dirty bike in the images.
