Shimano Shifter Inner Cable

Shimano’s Polymer-Coated and OPTISLICK cables deliver top-level performance for gravel riders of all kinds. These durable cables help ensure your shifting remains consistent thanks to different coatings or manufacturing processes to increase the "slickness" of the cable.

Shift cables need to slide easily within the cable housing to perform crisp gear changes. GRX mechanical shifters and derailleurs work together in precise increments so that each swipe of the shift lever moves the derailer exactly enough to shift the chain to the next cog on your cassette (or to the other chainring). The smoother the cable movement within the housing is, the more accurate and reliable the shift.
