Want to do me a huge favor? Could you tell me your frame size and then measure your head tube in mm? It would be the "E" measurement in this picture...
I'm trying to figure out if Bianchi only measures the head tube only (the steel tube itself and nothing else) or they also include the upper/lower headset sections. (The upper/lower headset sections will add an additional 20mm to the measurement) Thanks a lot.
The bike is a 55.
Is the picture what you are looking for?
The steel tube only is ~5 1/8" or ~130mm.
