Altus SL-M315-8R 8-Speed Right Rapidfire Plus Shifter

The shifter comes with a slim main lever body for easy handling. Its numbered gear display, located below the handlebar, lets you quickly see your gear position. Shimano's OPTISLICK cables have a thin and even electrical coating. This not only makes cable routing more efficient but also gives excellent corrosion resistance.

The 2WAY - RELEASE feature allows you to shift either by pulling with your index finger or pushing with your thumb. It comes in a sleek black color and has a trigger - style shifter, compatible with Shimano mountain rear derailleurs and an 8 - speed drivetrain.

Using the Shimano Altus SL - M315 Shifter is easy. To shift gears, you can either pull the index finger lever or push the thumb lever thanks to the 2WAY - RELEASE feature. When you're in a hurry to change gears, the RAPIDFIRE PLUS technology lets you quickly downshift three gears in one stroke. Keep an eye on the numbered gear display below the handlebar to know your current gear. As for maintenance, it's a good idea to regularly check the OPTISLICK cables for any signs of wear or corrosion. Since they have a special coating for corrosion resistance, they should last a long time, but it's still important to keep them clean. Also, make sure the shifter is properly attached to your bike's handlebar. If you notice any issues with shifting, like it being too hard or not accurate, it might need some adjustment. You can take it to a professional bike mechanic if you're not sure how to do it yourself.
