Review on Upgrade Your Bike Shifting With Jagwire Universal 2X Elite Sealed DIY Shift Cable Kit: SRAM And Shimano Compatible With Ultra Slick Cables And 3 Color Choices by Doug Hawkins

I was in the market for new inners and outers on my 2x9 Sora gravel bike last summer, and after tearing the bike down, aligning the rear derailleur, and installing these cables, one of the first things I noticed is that the shifting was about as buttery smooth as my Ultegra road bike. It really breathed some life into my gravel bikes lower-mid-range groupset. I've taken it on a couple longer gravel rides in some Minnesota springtime mud, standing puddles in reddish clay that dries like concrete on the frame, and thanks to the sealed cables, haven't had any issues with that mud working its way into the outer by the rear mech. Installation was fairly easy, just a couple extra steps, sliding the liner through.
