Safety Notice
CAUTION
Information on installation, adjustment and replacement of products not found in the user manual will be provided at the point of purchase or at the distributor. The dealer's manual intended for professional and experienced bicycle mechanics can be found on our website (https://si.shimano.com).
For safety, please read this "user manual" carefully before use, follow it for proper use, and save it for future reference.
The following instructions must be followed at all times to avoid personal injury and physical damage to the equipment and the environment. The instructions are classified according to the degree of danger or damage that may occur if the product is used incorrectly.
DANGER - Failure to follow the instructions will result in death or serious injury.
WARNING - Failure to follow the instructions could result in death or serious injury.
WARNING - Failure to follow the instructions could result in personal injury or physical damage to the equipment and surroundings.

WARNING
- Do do not disassemble or modify the product. This may cause the product to malfunction, you may fall unexpectedly and be seriously injured.
- Before riding the bicycle, check that the wheels are securely fastened. Improper use of the axle release lever can cause the wheel to fall off, etc. and may result in serious injury from a fall or collision.
- Use the appropriate air pressure marked on the tire and rim. If the maximum pressure is indicated on the tires or rims, do not exceed the maximum pressure with the lower value. A pressure higher than that can cause a sudden puncture and/or sudden release of the tire and cause serious injury. WH-R9270-TL / WH-R8170-TL / WH-RS710-TL: maximum pressure = 7.5 bar / 109 psi / 750 kPa 800 kPa
WH-RS370-TL: maximum pressure = 6.5 bar / 94 psi / 650 kPa
WH-RX880-TL / WH-RX870-TL / WH-RX570-TL: maximum pressure = 5 bar / 72 psi / 500 kPa
- Before riding the bicycle, check the wheels to make sure that the spokes are not bent or loose and that the surface of the rim no nicks, scratches or cracks. If you notice any of these problems, do not use the wheel. The wheel can break and you can fall. Check that there is no peeling or cracking of the carbon.
- Do not use the road wheel assembly on unpaved surfaces. The set of road wheels is intended for paved surfaces. If the wheels are used on unpaved surfaces, they may be bent or damaged, resulting in an accident.
- Do not use the GRAVEL wheel set in rough conditions, such as uneven roads. Do not use it for downhill or freeride cycling, otherwise the wheel may bend or otherwise be damaged if subjected to a strong impact and result in an accident.
- Do not use with rim brakes. These wheels are designed exclusively for use with disc brakes. Using these wheels with rim brakes can damage the rims and cause an accident that could result in serious injury or even death.
- Check that the axle release lever does not interfere with the disc brake rotor even when it is fully engaged. If the axle release lever is on the side of the disc brake rotor, it can interfere with the disc brake rotor, which is dangerous. If the axle release lever interferes with the disc brake rotor, stop using it immediately and contact your place of purchase or distributor.
- Details of the E-THRU axle can be found in the E-THRU axle user manual.
- Tires should be installed and removed by hand. If this is difficult, you can use a resin tire lever for tubeless wheels. In such cases, be sure to check the surface of the rim for dents, scratches or cracks, as there is a risk of damage to the air seal between the tire and the rim, resulting in air leakage. For carbon rims, check for carbon flaking or cracking. Finally, make sure there are no air leaks.
F12 (Front 12mm axle), R12 (Rear 12mm axle) wheel (hub axle)
- This wheel can only be used in combination with a special front fork/frame and hub axle. If used in combination with any other front fork/frame or hub axle, the wheel may detach from the bike while riding, resulting in serious personal injury.

WARNING
- Please note that a taller rim is more easily affected by wind and causes riding instability. Make sure you are aware of such increases. Otherwise, you may lose control of the bike, fall and seriously injure yourself. The same situation occurs when replacing brake pads or disc brake rotor.
