- Shimano TL-EW02 tool (for E-TUBE connections)
- Isopropyl alcohol and clean rags
- Double-sided tape or zip ties
Installing the Shimano SW-R610 Sprint Shifters
The installation process of the SW-R610 sprint shifters ensures that they are properly positioned for maximum accessibility and comfort during sprints. Before installation, check that your handlebars are clean and free of debris to ensure a secure attachment.
The sprint shifters are designed to be mounted inside the drops of your handlebars, just beneath your brake hoods. Start by selecting a position that allows easy thumb access while gripping the drops. Once you have chosen the optimal placement, attach the shifters securely using either double-sided tape or zip ties. This will prevent movement while sprinting and ensure precise shifting.
Once the switches are securely in place, route the E-TUBE cable along the handlebars toward the Di2 junction box. Use the Shimano TL-EW02 tool to connect the sprint shifters to the system, ensuring a firm and secure connection. Test the shifters by pressing the buttons and confirming that the Di2 system responds correctly. If the shifters do not function properly, check the cable connection and update the firmware via the Shimano E-TUBE PROJECT software.
Adjusting the Shimano SW-R610 Sprint Shifters
Customization of the SW-R610 sprint shifters ensures that the shifting functions match your riding style and sprinting technique. The switches allow for programming through the Shimano E-TUBE PROJECT software, offering a personalized experience.
To begin adjusting the shifting functions, connect the bike to the Shimano E-TUBE PROJECT app via a computer, tablet, or smartphone. Once the system detects the SW-R610 sprint shifters, assign the shifting functions based on preference. The left switch can be set to control front derailleur shifts, while the right switch can control rear derailleur shifts. Alternatively, both switches can be programmed to operate rear shifting only, allowing for quick and intuitive gear changes during sprints.
Shimano’s multi-shift mode can also be enabled, which allows the shifters to continuously shift gears when the button is held down. This feature is particularly useful in race situations where rapid gear changes are required. Once all adjustments are complete, save the settings and test the functionality of the sprint shifters to ensure they perform as expected.

Maintaining the Shimano SW-R610 Sprint Shifters
Routine maintenance of the SW-R610 sprint shifters is crucial to ensure long-term functionality. Regular cleaning of the switches and wiring prevents dust buildup and potential signal disruptions. Use a clean rag and isopropyl alcohol to wipe down the shifters, removing dirt and sweat that can accumulate during intense rides.
Inspect the E-TUBE wiring for any loose connections or signs of wear. If you notice any damage to the cables, replace them immediately to prevent shifting failures. Secure all wiring properly to avoid unnecessary tension or movement, which could affect the shifting response.
Firmware updates play a vital role in maintaining optimal performance. Shimano frequently releases updates that improve shifting algorithms and system reliability. To check for updates, connect the Di2 system to the Shimano E-TUBE PROJECT software, follow the on-screen instructions, and install the latest firmware versions. After updating, test the sprint shifters to confirm that they function correctly.
