At least three times now I have been stranded with a busted shifter cable.
The problem is I have a massive hill at the end of my ride and I just can't get up it without the ability to shift to the biggest ring.
I guess it must happen once a season.
So my cables are never more than a year old.
I do live in hilly New Hampshire so maybe it is just that I shift more than someone in Kansas.
I have ultegra shifters and derailleurs.
These are the ones I have been buying at Amazon (they get good reviews):

Can someone link to something that might be better?

Thanks
