We are committed to do everything to keep your TORZC wheels running in good condition.

Carefully read the instructions provided in this manual.  Failure to follow any instruction in this manual may damage the product and result in an accident, personal injury or death.  Please always remember that riding a bicycle involves potential danger for the rider and other road users, as well as the bicycle and its components.  Rely on your common sense and avoid any unreasonable behaviour.

All TORZC wheels are the result of manual labour, deviations in pattern or surface finish are characteristic features of this procedure.

Intended usage

Any use other than that intended usage can cause accidents resulting in death or serious injury.  All TORZC products have been designed and manufactured to be used on “racing” type bicycles specificed on paved roads. Any other use of this product is prohibited and may cause accidents, injury or death.


Assembly, maintance, and repair

Installation, repair qualification

Be advised that many bicycle service and repair tasks require specialized knowledge, tools and experience.  Do not overstimaite your technical ability.If you have any doubts regarding any service/repair of the wheels, please take your bicycle to a qualified repair shop.

Lifespan inspection

The lifespan of TORZC wheels depends on many factors, such as mileage, riser size, used tires and riding conditions.  Impacts, falls, crashes, or any improper use may compromise the structural integrity of the wheels and significantly reduce their lifespan.  Some components of the wheels are subject to wear over time.  Please have your wheels regularly inspected by a qualified mechanic for any cracks, deformation, signs of fatigue or wear.  If the inspection reveals any deformation, cracks, imp marks, or stress makes, immediately replace the component.

  • If you weigh over 130 kg, we advise you not to use this product.  Noncompliance with this warning can damage the product irreversibly.
  • If you weigh 85 kg or more, please inspect the components more frequently. Check with your mechanic to discuss whether the wheels you selected are suitable for your use and to determine the frequency of inspections.

Brake pad for the rim braking system

For wheels using a rim braking system, you must the proper brake pads for your rims.  Use of improper or contaminated brake pads will lead to excessively high braking temperatures, which can cause premature rim wear and/or failure, which can lead to serious accidents.

  • Use only the pads included with your wheels.  Using any other pads may generate heat that can lead to rim failure causing serious injury.
  • Do not re-use any brake pads on carbon rims that have previously been used on aluminum rims, as abrasive material may be embedded in the pad, causing damage on the carbon surface.

Tyres installation

TORZC tubeless-ready rims are designed for both tubeless and standard clinchers.

Rim/Tyre compatibility

TORZC rims are made with precision.  If fitting a tyre on a TORZC rim is too easy, it may be too big, and this will have significant implications for safety.  We recommend using only high-quality tyres that require the use of clincher tyre levers and a reasonable amount of strength to fit them.  Using a  tyre that is too high for the rim may cause the tyre to rupture unexpectedly and cause accidents, physical injuries or even death.

Fitting a clincher tyre

Incorrect mounting of the tyre may cause it to deflate, burst or detach suddenly and cause accidents, serious injuries or even death.

  • Ensure you do not damage or bend any part of the rim when fitting the tyre.  Damaging the edge of the rim may prevent them from operating correctly, especially if used with tubeless tyres.
  • If you cannot fit and remove the tyres by hand, use a plastic tyre lever.

Fitting a tubeless tyre

To use TORZC safely and correctly, there must be a perfect seal between the rim and the Tubeless tyre.  TORZC will not accept liability for the performance, quality or malfunctioning of a tubeless tyre.

Assembling a tubeless valve

Use only the original valve supplied by TORZC.  Periodically check the seal of the valve and the entire tubeless system.  To optimize the seal, we recommend changing the tubeless valve once a year.

Use of tubeless sealer

When installing tubeless-ready tyres, it is compulsory to use pierce-resistance sealers.  Never use sealers containing alkaline substances.

Inflating the tyres

Incorrect tyre pressure could cause the tyre to rupture suddenly and unexpectedly and/or lead to a loss of control of the bicycle and cause accidents, injury or even death.

  • Never exceed the maximum inflation pressure recommended by the tyre manufacturer for the cross-section of the clincher tire you are using.  Excessive pressure reduces tyre grip and increases the risk of the tyre bursting suddenly.
  • A pressure that is too low reduces wheel performance and increases the possibility of the tyre deflating, suddenly and unexpectedly. The pressure that is too low could also cause damage and premature wear of the rim.

Before each ride

Riding a bike with an improperly installed wheel can allow the wheel to move or disengage from the bike, causing damage to the bicycle, serious injury or death to the rider.  You must check and be sure both wheels are properly mounted to the frame before each ride.  Misalignment can result in problems with bike handling causing danger.

It is critical that you:

  • Ensure that your axle, dropout. and quick-release mechanisms are clean and free of dirt or debris.
  • Apply the correct techniques when installing your wheels.  Make sure that the wheels’ locking mechanism is properly adjusted.
  • Never ride your bicycle unless you are sure your wheels are installed properly and are secure.
  • Do not exceed the tire manufacturers’ maximum pressure recommendation when inflating tires.
  • Check your brake pads and cables to be sure they are in good condition and check that the brakes work properly before setting off.
  • Learn and observe local cycling rules.

On the road

Risk of accident due to damaged wheels

  • Avoid riding over potholes or over edges and steps.
  • After a violent impact and after a flat tire.  inspect before riding further.  If damage is visible or if you are worried about the structure of the wheels, do not ride further.
  • Never use defective or damaged wheels.

Risk of an accident caused by erratic riding behaviour or improper equipment

  • Exercise particular caution when riding during strong winds.  Front wheels with high profile susceptible to crosswinds causing unintentional manoeuvres.
  • Always comply with the local traffic regulations where you are riding.
  • Always wear a high-quality cycling helmet that is in excellent condition.  Your clothing should be in a bright colour for other road users’ visibility, close-fitting but not restrictive.
  • only ride your bicycle if you are in good physical condition, and your bicycle and all of its components are working perfectly.

Tyre puncture

If you have a puncture, even if it is only tiny, replace the tyre immediately.  A damaged tyre may burst suddenly, causing accidents, injury or death.
