Jipe are you happy with your current setup using Shimano Ultegra RD-R8000 derailleur considering how low it is while on smallest cog? Compared to Brompton, Birdy with, let’s call it standard derailleur is pretty low to the ground while on smallest cog, I wander how this derailleur is in that respect and if there are any derailleur alternatives you would recommend to consider which can be shorter (higher from the ground)? When I see Birdy pictures I always think how people manage to not yank it out on the rough surface.
