Not well designed? How much better do you think you could do? Let's hear it.
Hmmm. IDK, my 2017 gravel bike has about 6K miles and still has the original Jagwire housings. It's been through multiple cables due to hungry Shimano shifters and I just put a new set of shifters (right shifter broke) and cables on it. Shifting is flawless. Could it be even better if I replaced the housings? I can't imagine I would notice if it were better. It's spot on and never misses a shift.
