I´ve put "Clubman" bars on three of my CX-es. They give a riding position that I like far better than the rather flat and wide original bars did.
They have to be fitted so they don´t touch the tank at full amplitude. It´s my understanding that the picture is showing them upside-down, which also is the way I´ve fitted them. I have no idea if and how they would clear the tank when fitted the other way and how that would affect the riding position.
Some CX owners have tried my bikes. Not everyone liked how they felt. To me there´s no alternative. Semi-crouched, narrower between hands. Wide bars give you better control (leverage) but even M´lady has managed to ride with Clubmans without problem.
I´m rather short - 174 cm (5' 8.5"), as is M´lady too.
