General Safety Information

WARNING

• 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.

• 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

• Always be sure to use the sprocket set bearing the same group

Group marks marks. Never use in combination with a sprocket bearing a different group mark.

• 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 ag-15T ag-

• If the chain keeps coming off the sprockets during use, replace the sprockets and the chain.

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

• 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-
