Usually due to a lack of maintenance or regular cable replacement, a broken cable can be a big problem, especially if you’re stuck at the bottom of a climb! However, you don’t have to let a broken, frayed, or damaged cable or housing get the best of you. Cables will commonly break where they are most bent, usually at the shifter or under the bottom bracket. However, worn out cable housings can also fail and collapse if they are worn or corroded. This repair will lock your derailleur into one gear and is a bit more advanced; your multi-tool will really come in handy.
