Quick Summary
The Shimano Altus inner gear wire is a steel shift cable with a stated size of 1.2 x 2100 mm. It is described as an original Shimano cable and includes an end cap.
It is presented as a cable for front and rear shifting, so the main check is whether the length and cable type match the bicycle you are working on.

What to Compare Before Buying
- Cable type: This is an inner gear wire, so make sure it matches the shift system you are replacing.
- Length: The stated length is 2100 mm, so compare it with the route and reach needed on the bike.
- Diameter: The stated diameter is 1.2 mm, which should match the cable requirement for the intended gear system.
- Included end cap: Check whether you need a cable with the end cap included or prefer to use separate parts.
Compatibility, Size and Fit
This cable is described as suitable for front and rear shifting, and for road bike, MTB, city bike and others. The useful check is whether the cable type, length and diameter suit the exact bike and shifter setup you have.
For replacement work, confirm the routing path and any required finishing parts before choosing a cable length.
Before You Decide
Confirm the cable type, 1.2 mm diameter and 2100 mm length against your bike’s setup before choosing an offer. If you need a specific finish or fitting arrangement, check the included end cap and the exact shifting system you are replacing.
Check the Cable-End Fitting
Before replacing a cable, compare the end fitting on the new wire with the one required by your shifter. If you are using the old cable as a reference, check its fitting as well as its length and diameter; a matching size alone does not establish that the end will suit the shifting system.
