IMPORTANT: Before you ride, check: Is gear shifting happening smoothly? Is there any noticeable damage to the electric wires? Are there any unusual
noises during use??
You can shift gears while 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 8-speed hub has a built-in mechanism to support shifting. When this support mechanism operates during shifting, noise or vibration may occur.
The feel of the shifting may also change depending on the gear position at the time of shifting.
Noise may also be generated if the crank arms are turned backward or if the bicycle is pushed backward when the gear position is 5 – 8. These occur-
rences are a normal result of the structure of the internal gear shifting mechanism, and are not a sign of a malfunction.
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.
You should periodically wash the belt sprocket with water only.
If the belt begins to skip replace the gears and the chain at a dealer or an agency.
For more information about maintaining the hub or how to connect the hub with the shifter, please see the attached hub manual or visit www.shimano.

The internal gear hub is practically maintenance free.
Internal hubs sometimes make a little noise. This noise is caused by a pawl that is not engaging in a certain gear. There is no free wheeling while shifting
between two gears. This means that the pawl of the lower gear is still available in case the higher gear is not engaging yet. The clicking noise IS NOT a
sign that something is wrong on your internal hub.
HUB (FRONT WHEEL)
Hubs are sealed against dirt and humidity; however it is advisable to inspect the hubs regularly. To do this, remove the front wheel and turn the
axle with your hands. It should move freely, with very little friction. If it does not, have a mechanic change the hub bearings.
WHEELS
Removing the front wheel:
The front wheel is attached to the bicycle with bolts.
Use a 15mm spanner and unscrew the bolt, slowly remove the front wheel from the front fork.
REMOVING THE REAR WHEEL:
Remove the bolts on both sides of the axle with a 15mm spanner. Carefully remove the rear wheel, ensuring that no parts are still attached to the
bike.
WARNING: Be careful not to bend the belt and do not roll or pry belt on/off.
Truing an untrue wheel is a job for a professional. We suggest that you take your wheel to a bike mechanic store. Never remove your wheels if
you are unsure of the procedure. You risk damaging the chain, freewheel and the wheel itself. If you do remove the wheels yourself, be sure that
they are properly mounted and the quick-release/bolt is properly closed before taking a ride.
