What frame do you have
Ditching the FD and hanger saved 8-9w in testing.
But the larger rear mech (rival 1) cost 1w.
This was on a p4, which is optimised for low yaw and track and designed around no FD.
We tested 8 other bikes I think and found 1-4w on them.
Interestingly a larger ring seemed to add another 1-2w on, depending on the frame, we compared 52 with 58, maybe the larger ring somehow offers shelter?
We also added a very streamlined chain catcher, which obliterated all gains seen by removing the FD. In this area it’s not about size but about flow.
I'm on a 58cm P5, and I think the hanger is removable. 1-4w would be sad
