Ultegra 6800
#10
So I got a smaller horn with 10mm radius. Not much luck with the 20kg servo, got another with 35kg & 270 deg travel. That one pulls the derailleur however the current during hold is quite high, I see like 820 mA on the largest sprocket, about 600mA on the 2nd smallest and like 9mA on the smallest (idle). That’s only the servo. I guess that can only come from the derailleur spring force and not any friction. Some pics attached.
