I wonder why it was called that ?
As the original poster says !
Most rear mech's at that time had a slant parallelogram, eg' the old Campag' 70's -80's rear mech's pointed downwards
making them as aerodynamic as a brick in the wind but the SLJ6600 rear mech' had a Inline parallelogram which pointed
'into the wind' making it look more aerodynamic, If i remember i think it was Shimano who first invented the 'inline look'
The changing up or down of these rear mech's is so smooth i can genuinely say it is far better in
quality and looks than a 80's SR version, Never mock French Simplex stuff until you have tried them out.
I wished i'd have a more forgiving wife because i'd have this mech'
I hate RED DWARF
