I replaced old JAGwire cable with this and had fantastic shifting until recently. I noticed that the rear derailleur was needing a very small adjustment. Upon adjusting I noticed that shifting was now inconsistent. Further troubleshooting led me to find that the coating had started chaffing off. That made me feel extremely disappointed of what originally felt like a superb product.
I think I've done less than 500 miles on these cables. :-(
This is a reliable, well made set of shifter cables and housing that works with either SRAM or Shimano systems. You'll have to pre-stretch the cables a bit before locking down your pinch bolts permanently, but once that's done, you're shifting will be precise.
This is a very slick shift cable to use. Installation is easy and the cable is a very smooth and slippery in the cable housing. I did not install this in the 9000 or 6800 (installed on 7900). I was very careful and scraped the coating off the cable where it is clamped in with the fixing bolt, paranoid of cable clamp slippage. Not cheap, but a very smooth and slick cable.
Replaced the original 105 brifters with new versions that route cables on the handlebars. Shifting was basically OK but not what i expected from new equipment. Replaced the cables and housings with this package. Huge improvement.
What a difference these cables made in shifting performance. Easy to install and a good price. I have a set on my other bike thats been on for almost 2 years with a lot of miles and still shifting good.
