Speed Gearing Adjustment

The Shimano thumb shifter on the right handlebar uses a lever and a button to control the 7 rear cogs, providing 7-speed gearing for manual riding. Larger numbers represent smaller cogs and higher speeds. Smaller numbers refer to larger cogs and lower speeds.

To upshift, press the + button at the base of the shifter. To downshift, push away the lever beside the shifter. Be sure that your bicycle's crank is turning while using the shifter to adjust the chain on the cogs.
