How do I pair the EDS-TX with my bike computer and calibrate the system?

Download the WHEELTOP app on your smartphone, enable Bluetooth, and follow the in-app pairing wizard to connect both derailleurs—calibration is automatic and takes under 5 minutes. The app also manages firmware over-the-air (OTA) updates and allows fine-tuning of shift speed and trim adjustments without needing a computer or external software.
