I did set up another bike with Etap. Both my own bike and the other bike (not mine), have the lowest part of the cage 2mm from the top of chainrings tooths.
Even a hair less on some tooths.
This makes our chains run free from the "lump", in the "roof" of the FD cage.
The shifting works without rub, using all 11 gears with the 50T chainring and all 11 gears on the 34T and the 36T (my bike).
So, 22 gears you can use and you can cross chain how much you want.
No chain drops!
I have set both bikes with Sram Red chain catcher/ spotter. As mentioned above, i don't find Wickwerks Sentinel to work properly.
On my bikes, it interacts with the bottle cage and/ or the bottle itself.
I'd like to give your setup a try.
Compared to the lines that sram says to use, how far and in which direction does your setup deviate?
I don't think it deviates at all. The markings on the FD should be parallel to the chainring as Sram says.
Slightly different, well, perhaps at the 34/36T and 28T at cassette. I have more clearance between chain and inner plate of cage.
This is needed to have enough clearance for the 50T to be able to be at 28T (cassette).
Even if you don't or won't use this combo, you may by accident.
The "lump" in the "roof" is supposed to be near chain. It's to prevent chain from over-lifting, causing chain to be thrown over.
Ofcourse chain should never rub this "lump".
I don't find angling the cage a good idea. At the 50/11 it should be close, but not so close that it rubs.
I use a flashlight and look at both sides to see precisely what happens.
Regarding Sentinel, i don't appreciate this feature of Sentinel (rubbing bottle)
Personally it annoys me so i can't recommend this piece. The Red chain catcher is perfectly executed though!
