Product Description
The Shimano Dura-Ace SW-RS801-T Satellite Shifter Set adds remote shift buttons to the tops of your road or gravel handlebar, giving you fast access to gear changes during climbs and long seated efforts. It is a clean solution for riders who want additional shift points without moving their hands back to the main levers.

Designed specifically for 12-speed Shimano Di2 systems, these compact shifters mount near the stem on the flat section of the handlebar and connect directly to the satellite port on compatible STI levers. The 260mm integrated cable gives enough length for clean routing from the bar tops to the lever body.
