  • 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
    Use the CS-M771-10 in combination with an MTB 10-speed chain.
    If the wheel becomes stiff and diffi cult 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.
    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.
    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 maximum performance we highly recommend Shimano lubricants and maintenance
    products.
