I've already decided not to spend money on things that won't give a noticeable performance improvement. So far, I've only planned on replacing the saddle, the tires when they wear out, and maybe even the wheels in the future. Should quality cables/ cable housings be added to the list? Or are inexpensive cables and/or cable housings good enough for a low-end bike like this? If I do upgrade, I found a complete kit of Jagwire Pros for 40 USD. Are they worth it?
Don’t know from the info given if your issues are due to worn cables or bad setup (you did not even say if the bike is new or how old the cables are). But I doubt they are due to the quality of the cables.
If you do go with replacing cables and housing.....
I never found a difference between standard vs higher end shifting cables and housing.
I do notice a real difference in brake cables and housing (more specifically the housing). Compressionless housing (such as the Jagwire Pro) make for more solid feeling braking over standard brake housing. Jagwire Pro is my go-to for brake cables and housing sets.
