@SurferRosa thanks for the link. I needed something like that for my personal bikes. I buy this for all my lower-mid quality flips, it handles all shifting and brakes and actually works with the tighter-tolerance cable-end Simplex shift levers. Under $10 to cable an entire bike and never seen failure like OP is posting. https://www.amazon.com/gp/product/B00L8NDVD6/
