Description

Using the Shimano Sl - m640 Shift Lever is easy. Just grip it comfortably on the bar where it's directly installed. When you want to shift gears, use the ergonomic levers to smoothly change to the desired speed. There's a 2 - way release for added convenience. Remember not to use excessive force while shifting as it might damage the mechanism. For maintenance, keep it clean from dirt and grime. You can use a soft cloth to wipe it down regularly. Also, check the shifter cable and cable crimp occasionally for any signs of wear and replace them if needed.
