[. . . ] If the tension is too weak or the chain is damaged, the chain should be replaced. If this is not done, the chain may break and cause serious injury. · Obtain and read the service instructions carefully prior to installing the parts. [. . . ] · Use an outer casing which still has some length to spare even when the handlebars are turned all the way to both sides. Furthermore, check that the shifting lever does not touch the bicycle frame when the handlebars are turned all the way. · Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly. · Operation of the levers related to gear shifting should be made only when the front chainwheel is turning. ag -18T ag -15 T ag -13 T SH IM O AN HYPERGLI DE - C · 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.
