General Safety Information

WARNING

• Make sure that you understand the following points regarding the dropout thickness before use.

If the left and right end thicknesses are not within 7 - 10 mm, the dropout cannot be used. If you use a dropout with thicknesses that are less than 7 mm, the hub axle fixing nut will protrude and it will not secure the hub sufficiently. If it is more than 10 mm, the hub axle fixing nut will not be long enough to fully grip and it may damage the thread.

• Before riding, confirm that the hub axle has been tightened with torque of 35 - 45 N·m and the wheel has been secured to the frame. Serious injury can result from falling if the wheel comes off.

• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn, or damaged parts may cause injury to the rider. 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 lubricant to the inside of the hub, otherwise the grease will come out.

• You should periodically wash the sprockets in a neutral detergent and then lubricate them again. In addition, cleaning the chain with neutral detergent and lubricating it can be a effective way of extending the useful life of the sprockets and the chain.

• Always be sure to use the sprocket set bearing the same group marks. Never use in combination with a sprocket bearing a different group mark.

• Parts are not guaranteed against natural wear or deterioration resulting from normal use.

• For maximum performance we highly recommend Shimano lubricants and maintenance products

• For any questions regarding methods of installation, adjustment, maintenance or operation, please contact a professional bicycle dealer.
