Bike cables are used to operate two main bicycle functions. The brake systems use cables to move the calipers in and out, and thus slow down. Gear shifters also use cables to move the chain from one sprocket to the next.
Bike manufacturers often use their own unique specs for their bike cables. This most often refers to the length of the cable, and as such it is important that new cables are purchased for your specific make and model of bicycle. This will ensure that the cable will be the perfect match to your bike.
When purchasing bike cables, it is important to buy from reputable manufacturers. Companies that have been around for a while and have proven track records are much more likely to carry quality cables than any off-brand can provide. And of course, quality cables will inevitably last longer than inferior versions.
