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.
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.
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.
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.
