[. . . ] · Use the reinforced connecting pin only for connecting the narrow type of chain. · There are two different types of reinforced connecting pins available. If connecting pins other than reinforced connecting pins are used, or if a reinforced connecting pin or tool which is not suitable for the type of chain is used, sufficient connection force may not be obtained, which could cause the chain to break or fall off. Chain 9-speed super narrow chain such as CN-7701 / CN-HG93 8- / 7- / 6-speed narrow chain such as CN-HG50 / CN-IG51 Reinforced connecting pin Silver 6. 5mm Chain tool TL-CN32 / TL-CN23 Black 7. 1mm TL-CN32 / TL-CN23 Reinforced Connecting Pin · If it is necessary to adjust the length of the chain due to a change in the number of sprocket teeth, make the cut at some other place than the place where the chain has been joined using a reinforced connecting pin or an end pin. [. . . ] · 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.
