I'm having a lot of trouble finding short brake cable ferrules. The ones I've found are all long and tapered as in the picture below.
I don't understand the purpose of this design. The brake housing only fills half the ferrule, so the cable is effectively rigid for an extra centimeter. The housing is also loose because all the ferrules I have in this style (various brands) measure 5.2mm internally on the female side. The tapered end is loose in the cable stops on my bike and doesn't fit my mountain V-brake shifters.
What's the point? Why are the only short brake ferrules available the cheap crimp-style?
