I am tall. My bike is big. My aerobar extensions stick out far. I need a longer length of shift cable than what comes in the Dura-Ace shift cable kit.
The only thing I have found in bulk is Jagwire - which is cheap so I am guessing is also crap. Perhaps I am wrong. I have a Lyskey frame with all DA. I really don’t want to put any crap on this bike. Does anyone know where I can get some good shift cable in bulk or in a long length?
Housing? You should be able to go into any LBS and tell them how many feet you want and they’ll cut you a piece of their spool of housing.
For the actual cable, look for tandem bike length cable, there’s a DA version. And I think the jagwire stuff is probably fine quality. There is a HUGE markup on cables and housing.
