Shimano SG-3S30, a reliable 3-speed hub, offers smooth gear shifting for various riding conditions. It's suitable for navigating gravel roads, bumpy paths, uphill slopes, or when carrying heavy loads. The trigger lever operation is effortless, especially with reduced pedal force. Avoid placing your foot on the bell crank part for safety. Enjoy a comfortable ride on level surfaces with the "2" position and shift to "3" for faster pedaling.
