The rationale the O.D. is necessary is that the CF body has inside cables and the place the ferrules must ‘plug in” to the body, they should be the smaller exterior diameter model. Additionally, the OEM ferrules, Bianchi applied are silver alloy and for seems I feel I would favor to make use of a black ferrule, possibly plastic. Apparently, Bianchi used black ferrules for the shifter cable housing.
If I order Shimano cables and housing, which I’m prone to need to use, what can I count on to get for ferrules?
