FAQs
Does this set include the EW-RS910 junction box?
No, this is only a replacement set of holders (Holder A and Holder B) and does not include the electronic junction unit.
Can I use these for other Shimano junction boxes?
No, these holders are specifically designed for the EW-RS910 and are not compatible with other models.
Is any adhesive required for installation?
No, the holders are designed to be a friction fit inside the handlebar ends.
How do I know which holder is A or B?
The parts are usually marked. Refer to the official Shimano dealer manual (DM-R9150-03) for specific orientation diagrams.
Will these fit carbon handlebars?
Yes, they are designed for standard road handlebars, but always consult your handlebar manufacturer's documentation regarding bar-end accessories.
Troubleshooting
Junction box feels loose in the handlebar
Verify that Holder A and B are correctly oriented and that the handlebar internal diameter is compatible with the EW-RS910 specifications.
Difficulty inserting the unit into the bar
Ensure no e-tube wires are pinched or creating an obstruction behind the junction box; use a light amount of non-corrosive friction paste if recommended for your specific handlebar material.

Setup, Compatibility & Care
To install, first disconnect the wires from the EW-RS910 junction box. Slide the old holders out of the handlebar end, taking care not to pull on the internal e-tube wires. Position the new Holder A and B onto the junction unit as indicated by the Shimano technical manual, then gently press the assembly into the handlebar end. Ensure the cables are tucked away without kinks. For care, keep the area around the bar end clean of grit and grime to prevent debris from interfering with the port's charging pins. Regularly check that the junction box remains tight, especially after extensive travel where vibrations may loosen components.
