SHIMANO WH-7700 Front Wheel Mastroianni Classic Bikes
Product Introduction
WARNING
- Before use, check the wheels to make sure that there are no bent or loose spokes, dents, scratches or cracks on the rim surface. Do not use the wheel if any of these problems are found.
- Check that the recommended brake shoe holders have been installed, and that adjustment is correct. If the brake shoes are adjusted incorrectly, the brake shoe holder may contact the spokes when the brake is applied, causing noise.
- Do not use it in combination with brake types such as cantilever brakes in which the brake shoes move in an area pattern, as the brake shoes may gradually move closer to the spokes and touch them as the brake shoes wear.
- Do not use it in combination with bottom link-type suspension forks. With these types of forks, the clearance between the hub axle and the brake shoes can change due to the operation of the suspension, so that when the brakes are applied, the brake shoes may touch the spokes.
- If the quick-release mechanism is not used correctly, the wheel may come off the bicycle and serious injury could result. Read the Service Instructions for the quick-release mechanism thoroughly before use.
- Use rim cement to securely affix tubular tires to the rims. If the tires are not fully secure, they may come off the rims, and serious accidents and injuries may result.
- These wheels are designed for riding on paved surfaces. If the wheels are used on unpaved surfaces, the wheels may become bent or damaged, and accidents may result.
- Obtain, read and carefully service instructions when installing parts. Loose, worn, or damaged parts may cause injury to the rider. We strongly recommend that only genuine Shimano replacement parts be used.
CAUTION
- When the brake shoes become worn, the brake shoe holders may interfere with the spokes and cause frictional noise when the brakes are applied or brake performance may drop, even if the brake shoes have been installed correctly.
- If this occurs, replace the brake shoes as soon as possible.
- Two types of rim are available for use with either tubular tires or clincher tires. Use whichever type of rim is suitable for the type of tires used, and make sure that the tires are inflated to the correct pressure.
- If using the rim with clincher tires, use rim tape which can withstand high pressures, otherwise the tires may suddenly puncture and come off, and severe injury may result.
CAUTION
- The Shimano R55HC (high-performance) brake shoes use an aggressive compound designed with an emphasis on maximum performance in wet conditions, however, they will cause accelerated rim wear.
- Shimano accepts no responsibility for reduced rim life which might occur from using R55HC brake shoes with WH7700/6500 wheels.
- Use of genuine Shimano spokes, nipples and washers is strongly recommended. If non-Shimano parts are used, the area where the nipple seats into the hub flange 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 hub when the brakes are applied
- The nipples have large diameters and are easy to rotate to make it easier to increase the spoke tension.
- However, be careful not to overtighten the nipples when adjusting the spoke tensions. If the nipples are overtightened, damage to the rim may result.
- (We recommended that you ask authorized bicycle dealers to make the adjustments.)
