Thanks Simplex , i think that Dura ace AX logo on that aero post means it was meant to go with the AX aero group. I can just see a 6S engraving on the RDs pulley cage , is there a 7S right after it? and do you have 7Speeds? thanks Ian
Yes , it says "6S-7S SIS" , the earlier 6 speed 7400 mech doesn't have any writing there. I originally had 6 speeds and upgraded to 7 , it was the same freehub I think just the spacing changed.
