Check that the main lever assembly retaining screws are properly tightened. If the issue persists, the internal components of the lever assembly may be worn and require replacement.

Setup, Compatibility & Care
Compatibility: This part is exclusively designed for the Shimano ST-R7000 shifter. Ensure your existing shifter model is indeed ST-R7000 before purchasing.
Setup: Installation typically involves disassembling the shifter hood, carefully removing the old lever assembly, and installing the new one. It is recommended to refer to a Shimano service manual or consult a professional bike mechanic for detailed installation procedures, as improper installation can affect shifting performance and safety. Ensure all screws are tightened to the correct torque specifications.
Care: While the lever assembly itself requires minimal direct care, keeping your shifter mechanism clean from dirt and grime is important. Regularly clean the area around the shifter hood with a damp cloth. Periodically, it is advisable to lubricate the shifter's internal mechanism (following Shimano's guidelines) to ensure smooth operation.
