Shimano accepts no responsibility for reduced rim life which might occur from using R55HC brake shoes. Use of genuine Shimano spokes, plugs and washers is strongly recommended. If non-Shimano parts are used, the area where the spokes fit into the hub unit may become damaged. Before use, check that there are no pieces of metal or other foreign objects sticking to the brake pads. If any such items are present, they may cause damage to the rim when the brakes are applied. We do not recommend that you use general-purpose alkaline puncture repair agents, as they may cause the rims to corrode and allow air leaks to occur. The plugs have large diameters and are easy to rotate in order to make it easier to increase the spoke tension. However, be careful not to overtighten the plugs when adjusting the spoke tensions. (We recommended that you ask authorized bicycle dealers to make the adjustments. ) If the washer is not installed, it will not be possible to adjust the spoke tension, so be sure to include the washer. Tighten the nut as far as the edges of the thread.
