General Safety Information
WARNING
• 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.
• Do not use in combination with bottom link-type suspension forks. With these types of forks, the clearance between the hub axle and the brake shoes can change due to the operation of the suspension, so that when the brakes are applied, the brake shoes may touch the spokes.
• 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.
• These wheels are designed for riding on paved surfaces. If the wheels are used on unpaved surfaces, the wheels may become bent or damaged, and accidents may 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.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.
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.
• Special spoke wrenches are available as optional accessories.
• 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 (CP-WH23) are also sold separately. Please ask your bicycle dealer for details.
• 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.

• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
CAUTION
• The tires should be inflated to a suitable pressure before use.
• If using rims with clincher tires, use rim tape or spoke hole plugs for a rim size of
18-622 and 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 or spoke hole plugs after they have been removed from the wheel. If the tape or plugs are reused, the tires may suddenly puncture and come off, and severe injury may result.
Spoke lacing
Lace the spokes as shown in the illustration.
(For front)
At the front, a radial assembly is used at both the left and right.
(For rear)
At the rear, a tangent assembly is used at the both left and right.

Installation of the HG sprockets
For each sprocket, the surface that has the group mark should face outward and be positioned so that the wide parts of the gear projections on each sprocket and the A part (where the groove width is wide) of the freewheel body are aligned.

• For installation of the HG sprockets, use the special tool (TL-LR15) to tighten the lock ring.
• To replace the HG sprockets, use the special tool (TL-LR15) and
TL-SR21 to remove the lock ring.

CAUTION
• The Shimano R55HC (high performance) brake shoes use an aggressive compound designed with an emphasis on maximum performance in wet conditions, however they will cause accelerated rim wear.
Shimano accepts no responsibility for reduced rim life which might occur from using R55HC brake shoes.
• Use of genuine Shimano spokes and nipples is strongly recommended. If genuine
Shimano parts are not used, the hubs or rims may become damaged.
• Before use, check that there are no pieces of metal or other foreign objects sticking to the brake pads. If any such items are present, they may cause damage to the rim when the brakes are applied.
• The nipples have large diameters and are easy to rotate in order to make it easier to increase the spoke tension.However, be careful not to overtighten the nipples when adjusting the spoke tensions. If the nipples are overtightened, damage to the rim may result.
(We recommended that you ask authorized bicycle dealers to make the adjustments.)
