Shimano CA70 In-line Shift Cable Adjuster

These adjusters are designed to be installed in-line with your existing shift cable housing. You will need to cut a section of your housing—typically near the head tube or handlebars—and insert the adjuster between the two housing segments.

You will need a sharp cable cutter to cleanly slice your housing to the correct length. Beyond that, installation is straightforward and requires no specialized tools, though you should be comfortable with basic cable routing and derailleur indexing.

These are designed for standard mechanical shifting systems. They work with most road and mountain bike setups, but they are not compatible with electronic shifting systems like Di2, which do not use mechanical tension cables.

While many rear derailleurs have built-in adjusters, adding in-line adjusters allows you to make micro-adjustments to your cable tension while riding. This is particularly helpful for road bikes where the derailleur adjuster might be difficult to reach or for setups where the housing run is long and prone to cable stretch.

Yes, each pack contains two adjusters. This is sufficient to equip both your front and rear shifting systems if you choose to install them on both.
