Hmmm... So it seems responses vary quite abit, from the shifter cables never seem to wear out, to they break every 3000 miles - my personal experience. I feel like there is a whole new learning curve on maintenance going from the 5600 series to the 6800 series. Internal cable routing, press fit bottom brackets, dual pivot brakes. I guess it keeps the sport interesting...

I tend to ride in the same areas/routes in the same conditions, so it will be interesting to see if I get longer shifter cable life with the 6800 vs the 5600 series. I sure hope so, not looking forward to shelling out $40 each time I want to freshen up my shifting performance.
