User manual SHIMANO WH-7900-C24-TL ASSEMBLY

[. . . ] The hollow on the opposite side to the valve hole is an indicator for the amount of rim wear. If this hollow can no longer be seen, stop using the rim. If you continue using the rim, it may break, and the bicycle may fall over and an accident may result. Obtain and read the service instructions carefully prior to installing the parts. [. . . ] 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. If the plugs are overtightened, damage to the rim may result. (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. Note: 11T - 21T, 11T - 23T For installation of the HG sprockets, use the special tool (TL-LR15) to tighten the lock ring.

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 will come out. Special spoke wrenches are available as optional accessories. We recommend that you ask authorized bicycle dealers to adjust the spoke tensions if there is any initial play in the spokes and after the first 1, 000 km of riding.
