• Shimano 105 goes wireless. Precise and lightning-fast gear changes with the push of a button, without missing a pedal stroke, even when fatigue sets in or an unexpected climb is encountered.
• The shift to electronics also allows you to shift under load, such as during climbs or sprints. Customize your gear changes. Shift gears without performance drops - from Day 1 to Day 1000. And enjoy the silence while contemplating the world around you.
