Wheels, Cleaning and conservation

Danger! Check your tires for damage on a regular basis.You should exchange tires with worn threads or damaged sidewalls.

Damaged rim tapes have to be exchanged immediately. Damages at the tires may lead to a sudden burst of the tire and thus result in a serious fall.

When you exchange tires please note the maximum width limit of 50 mm (approx. 2 ").We recommend tires that are 32-40 mm wide.At the front wheel you have to use tires of ISO size 406 (20"), at the rear wheel ISO size 559 (26").The tire width possible at your bicycle depends on the size of your rims. Please ask your local dealer.

After you have exchanged the tires please check if the wheels turn freely and check the minimum distance between mudguards and frame.

The spokes of the wheels connect the rim with the hub.With disc brakes and at the rear wheel they additionally transmit the braking power and the pedal forces.

Danger! Take care that your spokes are always in perfect condition and the spoke tension is balanced. Do not ride with wheels that run untrue or wheels with loose or missing spokes.These faults may lead to a total failure of the wheel while braking and result in a serious fall!

Caution! To true up the wheels you need special skills, please have this work done by an experienced bicycle mechanic.

The wheels are fastened with a quick release lever and therefore they are susceptible to theft. For this reason always lock the wheels along with the frame to a solid object when you park your bicycle somewhere. It is also possible to exchange the quick release axles with axles that have special security locks (e.g. PITLOCK or KRYPTONITE) that can only be opened with a special tool.

Cleaning and conservation

The frame of the Street Machine GT has a high quality and environmentally friendly powder coating.The surfaces of the aluminum parts are either polished or anodized.

To keep the surfaces brilliant over many years and to protect them effectively against corrosion the bicycle has to be cleaned from dirt and then conserved.

Dried sweat but also environmental influences such as air pollution, dirt on the roads and especially grit affect the parts, and not only do they result in visual faults but also in serious structural damage of the parts through corro- sion.

In contrast to a widespread belief particularly the "non-rusting" aluminum is dramatically affected by grit! This kind of damage may not be visible in the beginning but it leads to a serious danger when the part breaks.
