I do love and use the hell out of Jagwire products, especially their basic pads for linear and caliper brakes, which are very lucrative when bought in bulk. They legitimately make compelling products at a very, very reasonable price point.

The only reason I opt for the Schwinn kit and choose it over Jagwire is because it comes with 4 complete cable housings, i.e. 2 for shift and 2 for brake, loaded with universal brake cables with correct ends to fit road and BMX style levers so it'll work with anything, plus both shift cables that don't rust easily and use a smaller barrel head (vs. the Jagwire disc head, although Schwin kit's shift cable has one barrel end, one disc end, you cut off the one you don't need) that fits Simplex, plus all the ferrules and crimps you'll need to install. All in one kit. Everything you need to completely overhaul all shifting and braking on one bike, previously for $10, now $13.

With the abundance of tools I have on hand, I'm probably saving at least $3-$5 using the Schwinn kit and still getting quality stuff I'd feel confident riding daily. But on my prize bikes and-or more modern bikes, on my shift cables at least, I'm typically using Jagwire or Shimano singles with Jagwire housing. The average novice or even newbie will probably save $10-15 using the Schwinn kit, if not more.
