a) Incorrect use, installation, maintenance or servicing can result in accidents and cause serious damage. Follow the instructions listed here to avoid accidents.
b) The assembly and maintenance of wheels and accessories requires knowledge of how to handle bicycle parts. Consult a competent person if you are in doubt. Always check the correct attachment of the wheels to the bike.
c) The permitted “Maximum System Weight” of the wheels must not be exceeded.
d) The maximum permissible pressure must not be exceeded, depending on the section of the tires you are using. You must consult the appropriate tables available on the manufacturers’ websites.
e) The wheels must be compatible with the other components/parts of the bike.
f ) Wheels must not be modified.
g) Wheels must not be used if they are damaged. The same applies if they have any signs of damage or the beginnings of damage. Always check before and after each use.
h) Check the spoke tension, rotation and any wheel wear regularly.
i) The wheels may only be used for their intended purpose. If is not the case, the user bears full responsibility.
j ) Brake discs and rims with brake track become hot during use. It is necessary to allow them to cool down before working on the wheels.
a) Do not use metal levers to install the tire. They can damage the rim, the tire or inner tube.
b) Tire installation is an important and critical operation. We recommend installing the tire without the use of levers. If using levers is unavoidable, then use suitable levers that do not damage the rim. In order not to put pressure on the wheel, while using the lever install the tire in the rim channel, keep it off the ground.
c) Use valves with the correct diameter and length. The valve bore must not be altered.
d) Tubeless Ready Tape, inner tube and tires must be suitable for the rim size.
e) When washing the wheels do not direct high pressure water jets at the hubs and nipples to avoid water ingress which could damage the components.
3.1 Applying Tubeless Ready Tape. Unless otherwise requested, wheels are delivered with Tubeless Ready tape. It is necessary to select a tape of the appropriate width for the rim channel.
a) To apply the tape it is necessary to clean and degrease the rim channel with special detergents.
b) Keeping it taut, stick the Tubeless Ready tape, in the canal, around the entire circumference of the rim. Start to apply it starting at least 12/15 cm before the valve and cut the tape at least 10 cm after the valve; so that there is an overlap of about 20/25 cm.
c) The tape must be pressed well around the entire circumference of the rim to ensure a good grip.
d) For road and gravel wheels it is necessary to apply two turns of the tape. However, for tire pressures of more than 3 bar. it is necessary to apply a double turn of tape (e.g. in the case of using an inner tube).
e) To make the valve hole in the tape, use an awl of the appropriate size, taking care to make a perfect hole that does not break.
f) Then insert the valve in the hole, taking care to fit it according to the instructions of its manufacturer. Tighten the valve connecting ring by hand (max. 0.5 Nm), without using tools. Excessive pressure could damage the rim.
3.2 Installing Tubeless Tire
This operation must be carried out by a professional.
a) Mount the tire on the rim in accordance with the manufacturer’s specifications. To facilitate insertion of the tire into the rim channel, we recommend using water with soap or the appropriate tire installation fluid.
b) Inflate the tire to the pressure required to ensure that the tire sits properly in the rim flanges (shoulders). Do not inflate beyond the maximum permissible pressure. Check that the tire is correctly seated.
c) Allow the air to escape and unscrew the inner valve body (core) with the tool provided.
d) Using the special syringe insert the sealing liquid through the valve after screwing it onto the threaded outer body of the valve. For the amount of liquid refer to the instructions of the manufacturer of the sealing liquid.
e) Remove the syringe from the valve, refit the internal valve body and pressurize the tire, again ensuring correct installation in the rim channel.
f) Adjust the tire pressure to the desired level. Respect the maximum pressures foreseen for the rim and tire.
3.3 Installing Tubeless Tire
a) Follow the same procedure for installing the rim tape as for the Tubeless tape. You can use the Tubeless tape if you have already installed it, with a double turn of the tape.
b) Mount the tire on the rim in accordance with the manufacturer’s specifications. To facilitate insertion
of the tire into the rim channel, we recommend using water with soap or the appropriate liquid to install the tires.
c) Pump the tire up to the maximum permissible pressure. Respect the maximum pressure allowed for the rim and tire (in accordance with the manufacturer’s specifications)
d) Do not inflate beyond the maximum allowed pressure and check that the tire is correctly seated in the rim flanges. If in doubt, have it checked by a professional.
e) Adjust the pressure to the desired level and in accordance with the type of use of the wheel.
3.4 Fitting the brake disk
a) If the wheel has a hub with IS6 disc fixing (direct fixing with 6 screws) mount the disc ensuring that the tightening force of the screws is in line with the hub manufacturer’s specifications.
b) If the wheel is equipped with a Center Lock hub and you want to fit an IS6 brake disc, use a Center Lock adaptor and tighten the fastening ring nut respecting the maximum tightening force allowed by the manufacturer’s specifications.
c) If the wheel is equipped with a Center Lock hub and you have a Center Lock disc, mount the disc directly on the hub in accordance with the manufacturer’s specifications.
WARNING: Considering the importance of the operation for safety, if you have the slightest doubt, have the operation carried out by a professional.
a) Hub (See manufacturer’s technical manual)
– For normal conditions of use : Every year
– For heavy-duty use : Depending on needs/circumstances
Check the condition of the bearings which, depending on use, are the parts most subject to wear. Consult a professional.
b) Also check the spoke tensioning, rotation and any signs of wear on the wheel frequently : At least every 10 to 15 hours of use.
c) Check the wheel overall for damage : Before and after each ride.
d) For cleaning use a soft brush or a soft sponge in addition to a specific cleaning agent for cleaning bicycle components : After each ride.
Do not wash the wheels with high pressure jets and aggressive detergents.
e) Check the pressure of the tires : Before each ride.
The correct way of transporting and handling the wheels helps prevent damage.
a) Do not place objects or loads on top of the wheels.
b) If you secure your wheels with straps or straps, protect them to prevent damage.
c) Protect the wheels from direct sunlight when inside a vehicle in high temperatures.
d) Lower the tire pressure when the wheels are inside a vehicle and there are high ambient/external temperatures.
e) Use the appropriate bags to transport the wheels.
These instructions are specific to wheels with rim-skate brakes and are to be regarded as in addition to those listed in the previous sections (Operating Instructions Chapter 1 to 5)
SAFETY :” Danger Warnings”. Wheels with rim-skate brakes must be checked constantly to ensure that the brake track on the rim flange is intact and free from defects or damage, as well as the brake pads of the front and rear brakes.
a) First of all we recommend the use of suitable brake pads (SwissStop Black Prince only). The customer assumes full responsibility if products other than specified are used.
b) Brake with both brakes at the same time.
c) On long descents it is imperative to brake hard but briefly. Frequent and breaks between braking are imperative. Long breaks between braking improve the performance of the braking itself.
d) Do not allow the brake pads to rub (crawl) continuously in contact with the rims because this causes overheating of the braking track which can cause the rim to crack, especially in the flange area, the tire or the inner tube to burst. Braking performance is also negatively impacted. These events create dangerous situations and a high risk of accidents.
e) Wheels with rim-skid brakes have braking performance that is significantly reduced in wet or rainy conditions. It is therefore necessary to adjust the speed and use a riding mode that is appropriate to the circumstances.
f) The braking efficiency and effectiveness of shoe brakes on carbon rims is inferior to that of aluminum rims. Adjust your riding mode accordingly.
g) If you use wheels with carbon rims after using wheels with aluminum rims it is absolutely essential to replace the brake pads. There could be inclusions of splinters of aluminum which would certainly damage the carbon braking track.
h) After replacing the brake pads it is necessary to carry out some braking tests.
a) Check the degree of wear of the braking surface (braking track) of the rim:
– Carbon rims : if the braking track is worn then the rim must be replaced.
– Aluminum rims : there are wear indicators on the track. If they are no longer visible, the rim must be replaced.
b) Using an appropriate cleaning liquid, remove any contamination on the braking track, (e.g. oil, grease, other lubricants).
c) Remove any inclusions present on the braking track such as: chips, splinters or grains of any nature.
Considering the importance in terms of safety, it is essential that the wheel is checked by a professional.
