Do not disassemble or modify the product other than as stated in the information contained in this dealer's manual.
All manuals and technical documents are accessible online at https://si.shimano.com.
For consumers who do not have easy access to the internet, please contact a SHIMANO distributor or any of the SHIMANO offices to obtain a hardcopy of the User's Manual.
Please observe the appropriate rules and regulations of the country, state or region in which you conduct your business as a dealer.
For safety, be sure to read this dealer's manual thoroughly before use, and follow it for correct use.
The following instructions must be observed at all times in order to prevent personal injury
and physical damage to equipment and surroundings.

TO ENSURE SAFETY
TO ENSURE SAFETY WARNING
Be sure to follow the instructions provided in the manuals when installing the product. Only use SHIMANO genuine parts. If a component or replacement part is incorrectly assembled or adjusted, it can lead to component failure and cause the rider to lose control and crash.
Wear approved eye protection while performing maintenance tasks such as replacing components.
Be sure to also inform users of the following:
Check that the wheels are fastened securely before riding the bicycle. Using the axle release lever incorrectly may cause the wheel to fall off, etc. and lead to serious injury due to a fall.
Before riding the bicycle, 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. The wheel may break, and you may fall. Check also that there is no carbon separation or cracking.
Do not use the Road Wheel Set on unpaved surfaces. The Road Wheel Set is designed for paved surfaces. If the wheels are used on unpaved surfaces, they may become bent or damaged, and accidents may result.
Do not use with rim brakes. These wheels are designed exclusively for use with disc brakes. Using these wheels with rim brakes could damage the rims and result in an accident that can lead to a serious injury or even death.
Make sure that, even if the axle release lever is tightened as much as possible by hand, the axle release lever does not interfere with the disc brake rotor. The axle release lever may interfere with the disc brake rotor if it is on the disc brake rotor side, which is dangerous. If the axle release lever interferes with the disc brake rotor, immediately stop use and contact the place of purchase or a distributor.
Axle release lever
Disc brake rotor

TO ENSURE SAFETY
Do not touch the calipers or disc brake rotor while riding or immediately after dismounting from the bicycle. The calipers and disc brake rotor will become hot when the brakes are operated, so you may get burned if you touch them. Check that the brake system has cooled down sufficiently before attempting brake system maintenance.
Do not allow any oil or grease to get onto the disc brake rotor and brake pads. Riding the bicycle with oil or grease on the disc brake rotor and brake pads may prevent the brakes from operating and result in serious injury due to a fall or collision.
Read the disc brake manual carefully, and keep it in a safe place for later reference.
Use the appropriate air pressure indicated on the tire and rim. If the maximum pressure indicated on the tire and rim differ, be sure not to exceed the lower value.
For details on the E-THRU axle, refer to the E-THRU axle user's manual.
F12 (Front 12 mm Axle), R12 (Rear 12 mm Axle) Wheel (Thru Axle)
This wheel can only be used in combination with the special front fork/frame and the through axle. If it is used in combination with any other front fork/frame or through axle, it may cause the wheel to become detached from the bicycle during riding and result in serious bodily injury.
TL: Tubeless wheel
The tires should be installed and removed by hand. If this is difficult, a resin tire lever for tubeless wheels may be used. In such cases, be sure to check that the rim surface has not been dented, scratched, or cracked as there is a risk of causing damage to the air seal between the tire and the rim, which would result in air leakage. For carbon rims, check that there is no carbon peeling or cracking, etc. Finally, make sure that there is no air leakage.
Use the appropriate air pressure indicated on the tire and rim. If the maximum pressures indicated on the tires and rims differ, be sure not to exceed the maximum pressure with the lower value. A higher pressure than indicated can cause a sudden puncture and/or sudden release of the tire, which can result in serious injury. WH-R9270 / WH-R8170 / WH-RS710: Maximum pressure = 7.5 bar / 109 psi / 750 kPa
TU: Tubular wheel
Before riding the bicycle, check that the tires are securely glued to the rims. If the tires come off while riding, you may fall and get severely injured.
7
TO ENSURE SAFETY
CAUTION
Be sure to also inform users of the following:
If you will be using tire sealant, consult the place of purchase or a distributor. Tire sealant may damage the tire and rim.
TL: Tubeless wheel
When using an inner tube, do not add additional rim tape on top of the tubeless tape. Doing so may make it difficult to install or remove the tire, and it may cause damage to the inner tube resulting in a sudden puncture, which can cause the bicycle to fall over.
Be sure to use tubeless tape when using these wheels.
Do not use tape other than genuine SHIMANO tubeless tape. Otherwise, a sudden puncture may occur, and you may fall off the bicycle.
If you use a tire such as a Tubeless Ready tire that needs to be used with a sealant, use the sealant recommended by the tire manufacturer.
Do not overtighten the valve lock ring. If you tighten the valve lock ring too much, the valve seal may become deformed, and air leaks may occur.
For installation to the bicycle and maintenance
Refer to the tire size table in the Installation/removal section when selecting tires.
Read the tire manual carefully, and keep it in a safe place for later reference.
NOTICE
Be sure to also inform users of the following:
Use only the lubricants specified by SHIMANO.
It is recommended that you ask a place of purchase to adjust the spoke tensions if there is any deviation in the spokes and after the first 1,000 km of riding.
Optional reflector and spoke protector sets are available. Check the model number on the website specifications and please ask your bicycle dealer for details.
Do not use detergent or other chemicals when wiping the wheel, otherwise, the sticker on the rim may come off.
Products are not guaranteed against natural wear and deterioration from normal use and aging.
8
TO ENSURE SAFETY
For maximum performance we highly recommend SHIMANO lubricants and maintenance products.
For installation to the bicycle and maintenance
Use only genuine SHIMANO spokes and nipples. Otherwise, the area where the spokes fit into the hub body may become damaged.
Be careful not to overtighten the nipples when adjusting the spoke tensions. If overtightened, damage to the rim may result.
If the wheel becomes stiff and difficult to turn, perform an inspection.
Special nipple wrenches are available as optional accessories.
Check the specifications table (https://si.shimano.com) for compatible reflectors and spoke protectors.
For information on how to install and remove the tires, refer to the manual accompanying the tire.
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using the product.

Installing and removing the tubeless tires
Important safety information
WARNING
The tires should be installed and removed by hand. If this is difficult, a resin tire lever for tubeless wheels may be used. In such cases, be sure to check that the rim surface has not been dented, scratched, or cracked as there is a risk of causing damage to the air seal between the tire and the rim, which would result in air leakage. For carbon rims, check that there is no carbon peeling or cracking, etc. Finally, make sure that there is no air leakage.
CAUTION
When using an inner tube, do not add additional rim tape on top of the tubeless tape. Doing so may make it difficult to install or remove the tire, and it may cause damage to the inner tube resulting in a sudden puncture, which can cause the bicycle to fall over.
Do not overtighten the valve lock ring. If you tighten the valve lock ring too much, the valve seal may become deformed, and air leaks may occur.

6. Deflate the tire and check that the beads are locked into the rim.
When deflating the tire, the tire may separate from the rim if the bead lock is released from the rim and cause air leaks while riding.
7. Inflate the tire until it is at an appropriate pressure.
WARNING
Use the appropriate air pressure indicated on the tire and rim. If the maximum pressures indicated on the tires and rims differ, be sure not to exceed the maximum pressure with the lower value. A higher pressure than indicated can cause a sudden puncture and/or sudden release of the tire, which can result in serious injury. WH-R9270 / WH-R8170 / WH-RS710: Maximum pressure = 7.5 bar / 109 psi / 750 kPa
Removal
1. To remove the tire, deflate it and push one side of the bead into the center groove of the rim.

Cautions regarding the use of tubular tires and rims
Cautions regarding the use of tubular tires and rims
Important safety information
Compared to clincher tires, tubular tires require greater expertise when handling and mounting them. Additionally, greater care is required in their maintenance. Always inspect the wheels prior to use.
These precautions must be observed in order for the optimum performance features of this product to be obtained. If they are not observed, the tires may come off the rims or damage to the tires may occur resulting in severe injury to the rider.
Make sure that you read and fully understand the following points on using tubular tires. Furthermore, if you are not confident that you have enough knowledge and experience in installing and removing the tires or carrying out maintenance, ask an authorized bicycle dealer or a professional bicycle technician for assistance.
WARNING Do not use these tubular tires if you are not confident that they have been installed by someone with an adequate level of knowledge and experience.
When securing the tires to the wheel rims, use a special adhesive designed exclusively for tubular tires. If any other type of adhesive is used, it might not secure the tires in place with sufficient force, and it may also cause deterioration of the rim material.
When cleaning the rim surfaces, use only a cleaning agent which is exclusively designed for tubular tires. If any other type of cleaning agent is used, it may cause deterioration of the rim material. If using carbon rims, do not rub the surfaces of the rims vigorously with sandpaper or anything similar. Otherwise, the carbon fiber layer of the rims may peel off when replacing the tires.
Confirm that the tire is secured to the rim surface before using it. If the adhesive is not applied correctly to the rim surfaces, it may not hold the tires securely in place, and the tires may easily come off the rims. Particularly when using the rims for the first time, always be sure to clean the rim surfaces thoroughly with the correct cleaning agent to remove any traces of grease and other foreign materials, then apply a thin layer of adhesive to the rim surface to create a secure bond between the rim and the wheel. When this has been done, apply more adhesive evenly to the rim at a thickness which is just sufficient to cover the roughness of the tire and no more, then install the tire. When using rims that contain carbon fiber material, if the tires are not attached properly, or if the wrong type of adhesive or cleaning agent is used, it may not be possible to obtain the same adhesion force between the rim and the tire as with aluminum rims, and the strength of the carbon fiber rims may also be reduced.

Cautions regarding the use of tubular tires and rims
WARNING
Understand the properties of the adhesive before using it. Depending on the type of adhesive used, there may be large differences in factors such as adhesion force, the time it takes to dry, durability, and the sensitivity to conditions such as temperature and humidity. Therefore, you should pay particular attention to the adhesion force when using the wheels.
Always check the tires before use by applying force to the tires to make sure they are properly attached to the rims.
The adhesion force of the tires may deteriorate after long periods of use, therefore it is best to re-apply the adhesive periodically. If using carbon rims, use a rim cement cleaner or similar when replacing the tires to assist in peeling the tires off gently in order to avoid pulling away the carbon fiber layer.
Take care of the adhesive force of the tire and rim surface. If you do not apply any adhesive to the adhesion surface of the tire when installing the tire to the rim, the adhesion force between the tire and the rim will be weaker. If you want the tires to adhere to the rims with greater force (such as when riding in criterium competition races and track races where hard turning and acceleration are required) you can use adhesive to adhere them more firmly.
Take care when continuously using the brake. If the rims become hot as a result of continuous use of the brakes when riding down long descents, sudden loss of tire adhesion force may occur. If you think that this might happen at some stage, pay particular attention to selecting and re-applying the adhesive at some point. Loss of adhesion force can still occur even if measures are taken to prevent it, so if it still occurs, replace the wheels and discontinue using the tubular type of tires.
Also check the tires before use. If there are large cracks in the tires, they may burst during use, and so they should be replaced beforehand. In addition, the seam covers may come off the tires after long periods of use, and so check the tires before riding the bicycle.
If you feel a problem or abnormality, stop using the bicycle and consult a place of purchase or a distributor.
For any questions regarding methods of installation and maintenance, please contact your place of purchase or a distributor.
NOTICE
If any adhesive gets on the painting surface of the rim, use a cloth to wipe it off before it dries. Do not use cleaning solvents or
