NOTE
Be sure to also inform users of the following:
•
You can shift gears while lightly pedaling, but on rare occasions the pawls and ratchet inside the hub may produce some noise
afterwards as part of normal gear shifting operation.
•
The internal hub is not completely waterproof. Avoid using the hub in places where water might get inside it and do not use
high-pressure water to clean the hub, otherwise the internal mechanism may rust.
•
Do not disassemble the hub. If you need to disassemble it, consult the dealer where you made a purchase.
•
All of the following phenomena occur due to the internal gear-shifting structure and are not the failure of the internal
components.

The hub has a built-in mechanism
for facilitating gear shifting.
When the mechanism operates
during gear shifting, noise and
vibration may occur.

purchase.
