Da
SRAM Umwerfer aktuell, wie nahezu alles andere von
SRAM, sehr schwer zu bekommen sind, überlege ich stattdessen
Shimano (oder vielleicht sogar Campagnolo) zu kaufen. Würde die Kombination funktionieren? Kleines Problem wäre vielleicht die fehlende Trim-Funktion bei
SRAM Schalthebeln, sofern ansonsten kompatibel.

Könnte gehen (das kommt wohl auf den
Shimano-Umwerfer an), aus dem Weighweenies-Forum geklaut:
"FD-7900 has a longer linkage than other
Shimano FDs(FD-6700,5700,7800… basically all FD before the 11s groups, which have long upper arms like FD-9000), therefore it must be used with ST-7900 to operate properly.
There's a solution though. If you put a tab washer(the type of washer on rear derailleur's cable fixing bolt) under the FD-7900's bolt, than route the cable below the tab and bolt, the effective lever arm length is reduced to be compatible with
Sram shifter. Here's the example I used on one of my bike, the red arrow points to the tab of added washer:
After this mod, FD-7900 wil index correctly with
Sram shifters, as other short-armed
Shimano FDs do.
I don't use this setup anymore, IIRC, the shiftng feels similar to FD-5600(normal short-arm). I'm curious whether FD-9000/6800/5800 will work with
Sram shifter, but I'm more inclined to use
Sram 11s FD with yaw features, which should give the best results.Hope this helps."
