Refer to the Product Technical Information for details on combination with other parts such as chains and cassette sprockets.

General Safety Information

• Before use, check the wheels to make sure that there are no bent or loose spokes, dents, scratches or cracks on the rim surface. Do not use the wheel if any of these problems are found.
• If the quick release mechanism is not used correctly, the wheel may come off the bicycle and serious injury could result. Read the Service Instructions for the quick release mechanism thoroughly before use.
• The wheel is designed for cross-country riding. Do not use it for downhill riding, otherwise the wheel may become bent or otherwise damaged, and accidents may occur as a result.
• Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any way, they may come off the bicycle and serious injury may result.
• The hollow on the opposite side to the valve hole is an indicator for the amount of rim wear. If this hollow can no longer be seen, stop using the rim. If you continue using the rim, it may break, and the bicycle may fall over and an accident may result.
• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or damaged parts may cause the bicycle to fall over and serious injury may occur as a result. We strongly recommend only using genuine Shimano replacement parts.
• Specifications are available for dual disc brake and rim brake use, and also for disc brake use only (no rim brake braking surface). Do not use parts with specifications for disc brake use only with rim brakes, otherwise the brakes will not operate correctly.
• Be sure to carefully read the Service Instructions for the disc brakes also.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.

• The tires should be inflated to a suitable pressure before use.
• Use rim tape which can withstand high pressures, otherwise the tires may suddenly puncture and come off, and severe injury may result. Furthermore, it is not recommended that you reuse rim tape after it has been removed from the wheel. If the tape is reused, the tires may suddenly puncture and come off, and severe injury may result.

• Use of genuine Shimano spokes and nipples is strongly recommended.
• When using rim brakes, check that there are no pieces of metal or other foreign objects sticking to the brake shoes before riding the bicycle. If any such items are present, they may cause damage to the rim when the brakes are applied.
• When using rim brakes, it is not recommended that you use the brake shoes with the following product names with this product, because severe wearing of the braking surfaces of the rims may occur. R55HC, M70T3, M70T2, M65T3, M65T, M55T, M50T Furthermore, do not use brake shoes for carbon rims or ceramic coated rims either.

Note

• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.
• Do not apply any oil to the inside of the hub, otherwise the grease will come out.
• We recommend that you ask authorized bicycle dealers to adjust the spoke tensions if there is any initial play in the spokes and after the first 1,000 km of riding.
• Spoke protectors are also sold separately. Use the CP-WH13 when using the CS- M760 (11-32T), and use the CP-WH12 for all other cassette sprockets.
• For maximum performance we highly recommend Shimano lubricants and maintenance products.
• Reflectors (manufactured by CATEYE) are also sold separately. Please ask your bicycle dealer for details.
