OVERALL SAFETY WARNINGS

There are inherent risks associated with cycling. These types of risk can be a severe or fatal injury. 

Always follow the instructions in this guide, along with any other advice or guides provided to you by Rebel-Cycling. Failure to follow these instructions may result in severe or fatal injury.

If, after reading this guide or at any other time you still have any concern or doubt about the use, maintenance, repair or fitting of your Rebel Wheels, please contact us or refer to a qualified cycle mechanic.

INTENDED USE AND WEIGHT LIMITS

  • Only use the wheelset for uses stated in the product description at www.Rebel-cycling.com.
  • Do not use off-road unless this purpose is stated in the product description.
  • Do not use for mountain biking unless this purpose is stated in the product description.
  • Follow the rider & equipment weight limits in the product description.
  • Do not use disc brake wheelsets with rim brakes.
  • Do not use rim brake wheelsets with disc brakes.

Quick-Releases:

Please read this section carefully – failure to ensure that quick-releases are tightened correctly and sufficiently may result in severe or fatal injury.

  • Only use your Rebel wheels with quick-releases that are in 100% working order. If you are unsure whether your quick-releases are fit for proper use, either contact us or refer to a qualified cycle mechanic.
  • Before starting a ride, please ensure that the quick release is tightly closed. The quick-release should not be easy to undo. Make sure that the wheels are securely attached to the bike by pulling sharply on each wheel. The wheels should not move in the frame or fork.
  • Check that your frame and fork are compatible with quick releases before using.

FITTING & ADJUSTING QUICK RELEASES

  • Only operate the quick releases by hand and never use a tool as this may damage the mechanism – thereby making the quick-release unsafe for proper use.
  • Open the quick-release fully before fitting the wheels.
  • Before closing the quick-release, ensure the hub is fully inserted in the center of the fork or frame.
  • If the clamping force is not enough, open the lever and adjust the nut on the opposite side by turning the nut clockwise. Then fully re-close the lever.
  • If the clamping force is too high to close the lever, open the lever and adjust the nut on the opposite side by turning the nut slightly anti-clockwise. Then fully re-close the lever again – this should take a force sufficient to leave a temporary imprint of the lever on your hand.
  • Only adjust the quick-release tension with the adjusting nut on the opposite side to the lever.
  • Ensure that you re-close/attach brake cables if required.
  • Do not attempt to turn the adjusting nut with the lever in the closed position.
  • Ensure the lever is not touching any part of the bicycle when closed.
  • Keep your quick release lever’s cam clean and lightly lubricated to maximize its clamping efficiency.
  • Ensure the wheels are centered in the frame/fork before you tighten the quick-release.

Thru-axles:

  • When using your wheels with Thru-axles, only use the Thru-axles supplied by your frame or fork manufacturer.
  • When using Thru axles, check the instructions provided by your frame or fork manufacturer.

INSPECTING & LOOKING AFTER YOUR REBEL BIKE WHEELS

Wear and tear of components in your Rebel Wheels is normal and will occur as a result of regular use. If the components of the REBEL wheels is not attended to, these components may fail in use with a risk of severe or fatal injury. We strongly advise you should check the following regularly or at least once per month:

  • Check that bearings are running smoothly without excessive resistance. A small amount of roughness is acceptable, but if there is significant resistance, this indicates that the hub needs service and/ or the bearings should be replaced due to wear and tear. 
  • Only replace bearings with new bearings in matching size. A qualified cycle mechanic should only carry out the replacement. Wheels can also be returned to Rebel-Cycling for bearing replacement.
  • Check that spokes and nipples have not come loose.
  • Check for signs of damage to the wheel components at the rim bed where spokes are attached and on the spoke nipples.
  • Check for trueness and roundness. If your wheel needs to be re-trued, please refer to a qualified cycle mechanic. Wheels can also be returned to Rebel-Cycling to be re-trued.
  • Check the freehub mechanism is engaging correctly, and clean and lubricate if necessary.
  • Check for wear on your brake pads regularly.
  • Check the braking track for wear or loose fibers. If the brake track is worn or loose fibers are showing, discontinue use of the wheel immediately.
  • Check threaded axle adaptors/axles are correctly tightened.

If using your bike in wet weather or off-road, then check your wheels at least every week or every 160 km.

IMPORTANT WARNINGS

Bicycle wheels are subject to wear and stress in use. Different materials and components wear or fatigue from stress to varying rates with varying cycles of life which will vary extensively depending on the conditions in which they are used and the loads they are exposed to. 

If a component’s life cycle is surpassed, the part can suddenly and catastrophically fail without warning, causing severe injury or death to the rider. Therefore, you must frequently inspect components for any signs of wear or fatigue. If you have any questions, always consult a qualified cycle mechanic, or contact us. 

Scratches, cracks, bending, fraying, or discoloration are all signs of stress-caused fatigue and may indicate that a component is at the end of its life cycle and needs to be replaced. 

When and if you see any of these signs, please stop using your wheels and take them to a qualified cycle mechanic for inspection, repair or replacement if necessary. Products can also be returned to Rebel-Cycling for inspection.

  • Road salt can accelerate corrosion of metal parts. Any road salt residue must be cleaned off as soon as possible.
  • A warranty may cover the materials and quality of your wheels for a specified warranty period, but this is not a guarantee that the product will last the term of the warranty without failure. The warranty does not suggest that the bicycle or component cannot be broken or will last forever. It only means that the product is covered subject to the terms of the warranty.

REPLACING SPOKES

Fractured spokes are rare but sometimes happen. Usually, the cause of a broken spoke is due to normal wear and tear. You can purchase replacement spoke for all Rebel wheels at www.Rebel-cycling.com

ADDITIONAL INFORMATION

  • Never clean your wheels using a pressure washer; this will damage and reduce the life of the bearings significantly. Wash using only water and soap or a specialist bike cleaner.
  • Do not use solvents, detergents, paints, or abrasives as these may damage the wheels. This damage may not be visible.
  • Do not leave exposed to high temperatures, for example, in a hot car.
  • Excessive UV light can degrade the epoxy resins in carbon fiber over time. Avoid storing carbon rims in direct sunlight.
  • Do NOT apply any lubricant, grease, or oil to the brake pads or braking surfaces. If any of these substances do come into contact with the brake pads or braking surface, clean thoroughly with soap and water.
  • Some braking noise may occur with new wheels or brake pads. This is normal, particularly with carbon braking surfaces. This noise should stop when the pads have been run in.
  • You should also check your wheels carefully for damage after an accident or significant impact such as running through a pothole.
  • If you are in any doubt about maintenance, inspection, repair or any other aspect of owning your Rebel Wheelset, then you should contact a qualified cycle mechanic or get in touch with us.

BRAKE PADS & BRAKE SETUP

  • Only use brake pads specifically designed for carbon rims on REBEL carbon wheels.

 

  • Follow instructions provided by your bicycle or component manufacture when fitting brake pads and setting up brakes.
  • With carbon braking surfaces, braking distances will be increased in wet conditions. Therefore reduce speed and brake earlier in damp weather.
  • Check brake pad surfaces regularly for contamination by dirt, grease, oil or particles that may affect braking performance or even damage braking surfaces.
  • Check the brake pad wear indicator regularly and replace brake pads when required.

BRAKING SAFELY

Sustained periods of braking may cause excessive heat to build up in your wheels. This affects braking performance. On rim brake wheelsets, this heat may cause increased tyre pressure resulting in the failure of tyres or tubes with a risk of severe or fatal injury.

Temperature build-up will be most severe in the circumstances below:

  • Long and steep descents
  • Riding on hot days
  • High rider- & equipment weights
  • Stop regularly on long descents & allow your braking surface to cool before continuing. This is particularly important if you are braking continuously.
  • If you suspect your brakes have heated up significantly you MUST stop immediately and allow them to cool.

Rebel Wheels are designed to be able to take a beating and have a high strength to weight ratio. But with almost everything else, they have their limits and are not to be considered in-destructible. 

Impacts of sufficient force will damage or destroy a bicycle wheel. Impacts from sharp or square edges such as from a pothole can cause severe damage to the wheel. 

High energy impacts, such as an accident or heavy landing, especially if the wheel is impacted from the side, may also cause severe damage to the wheel. 

  • Rebel Wheels can be damaged through impacts by rocks, potholes and other road and trail obstacles. This damage is not covered under our warranty, but we offer a Crash Replacement Plan. See more information here “link til crash replacement”.
  • Excessive force or the improper use of tyre levers during tyre installation or removal can dent and damage carbon rims. This type of damage is not covered under our warranty.
  • Crashing your bike can exert forces upon a wheel much higher than experienced through everyday riding. This can result in damage to the wheel components which could render them unsafe to use. Even if no damage is initially visible, we strongly recommend the wheels to be thoroughly inspected by a qualified and experienced cycle mechanic.
  • Accidental damage is not covered under warranty.
  • Products should not be used outside their recommended usage. Wheels designated for road use should not be used for MTB riding. Gravel and cyclocross wheels should not be used on mountain bike trails, and mountain bike wheels need to be used within their limits such as cross-country, trail use or downhill.
  • The use of a product outside of its intended usage such as riding rough downhill mountain bike tracks on lightweight cross-country wheels could cause the product to fail and severe injury or death to occur.
  • Regularly riding near to a wheelset’s limits will fatigue and shorten the lifespan of the product. Therefore, we recommend that if a wheelset is being ridden in this manner that it is inspected on a more regular basis.
