caption_attribution_description: English: Microshift R8 gear shifters for the chainrings. There are two levers to move the chain up or down one gear at a time.
context_page_description: A bicycle shifter or gear control or gear levers is a component used to control the gearing mechanisms and select the desired gear ratio. Typically, they operate either a derailleur mechanism or an internal hub gear mechanism. In either case, the control is operated by moving a cable that connects the shifter to the gear mechanism.
context_section_description: There are various types of shifter:
  Grip shifter - a wheel with click stops surrounding the handlebar is turned until the desired gear is reached, though typically one gear at a time
  Trigger shifter - a lever is pulled or pushed to change gears one at a time
  Thumb shifter
  Road bike shifter - integrated with brake levers, sometimes known as a "brifter".
