INTENDED USE, RIDER & EQUIPMENT WEIGHT LIMITS
• Only use the wheelset for uses stated in the product description at www.huntbikewheels.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.
• Do not use on tandems or trikes.
• 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 & THROUGH-AXLES
- Please read this section carefully – failure to ensure that quick releases are tightened correctly and sufficiently may result in serious or fatal injury.
• Only use your wheels with the Hunt Bike Wheels quick releases supplied with the wheels at the time of purchase or a Hunt Bike Wheels replacement set. If you are unsure which quick releases to order, please contact us.
• If you are using your wheels with through axles, only use the through axles supplied by your frame or fork manufacturer. Only use Hunt Bike Wheels adapters. User guides for adapters can be found at www.huntbikewheels.com
• Before every ride ensure that the quick release is tightly closed. The quick release should not be easy to undo, and when in the closed position the ‘Hunt’ name should show on the outside of the quick release. 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.
• If using through axles check the instructions provided by your frame or fork manufacturer.
• Check that your frame and fork are compatible with quick releases before using.
FITTING & ADJUSTING QUICK RELEASES
• Only operate quick releases by hand, never use a tool as this may damage the mechanism making it unsafe.
• Open the quick release fully before fitting the wheels.
• Before closing the quick release ensure the hub is fully engaged in the centre of the fork or frame.
• If the clamping force is not enough, then 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, then 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.
• Check that the end of the quick release skewer is not recessed by more than 2mm inside the outer side of the adjusting nut.
• 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 maximise its clamping efficiency
• Ensure the wheels are centred in the frame/fork before you tighten the quick release.
INSTALLING YOUR HUNT BIKE WHEELS & THIRD PARTY COMPONENTS
• For instructions on how to install your Hunt Bike Wheels and fit any third party components see the instructions provided by your bike or third party component manufacturer.
• Check that any third party components are compatible with your Hunt Bike Wheels before attempting installation.
FITTING TYRES, TYRE WIDTHS & TYRE PRESSURES
- Please read this section carefully - failure to follow the advice below and our guidance on www.huntbikewheels.com or elsewhere may result in failure of your tyres which can cause serious or fatal injury
• Please follow the tyre pressure information for your wheels at www.hunt- bikewheels.com in the user manual section.
• Please follow suitable tyre size information on the wheelset product page for your wheel model name at www.huntbikewheels.com, if unsure please contact us for accurate tyre size information for your wheels.
• Only use tyres compatible with the ETRTO rim diameter for your wheels. This may be printed on the side of your rims and is also available on the web- site product page for each current wheel model, if you have a discontinued wheelset or are at all unsure please contact us for the ETRTO for your wheels.
• Ensure that the manufacturer of your chosen tyres states that they are compatible with your rims before fitting. This includes, but isn't exclusive to, ensuring that the tyre manufacturer recommends the fitting of their tyres to your wheelsets rim width.
• Follow any advice on tyre suitability on www.huntbikewheels.com or other advice we may provide to you - including in the product listing or email communication from us.
• Ensure that the tyre fits securely to the rim when fitting and cannot easily fit over the rim lip. DO NOT USE if the tyre can be removed without tyre levers.
• DO NOT USE tyres that have previously been fitted to another wheelset. These may have been stretched in use causing an insecure fit on your HUNT wheels. Also, do not use tyres that are damaged in any way, including tyres that have blown off a rim under pressure - there may be unseen damage such as a stretched bead that could compromise their safety.
• H-Lock Wedge rims – (used on some models of 55 Carbon Wide Aero, 30 & 50 Carbon Aero Disc (November 2016 to January 2018) and 30 Carbon Gravel Disc rims (November 2016 to January 2018)) should only be used with tyres specifically designated as TUBELESS or TUBELESS READY and constructed with CARBON BEADS. These tyres have predictable bead diameters and a strong bead construction. You can use inner tubes with these Hunt HLW rims as long as they are used in tubeless tyres. Tyres constructed with Aramid/ Kevlar beads including, Hutchinson Fusion 5 tyres, Continental GP5000 TL, Specialized 2Bliss tyres and Mavic tyres are not suitable for use with HLW rims. Continental also state that their tubeless tyres must only be used on hooked tubeless ready rims so are also not suitable for use with HLW rims. Ultimately if in any doubt please contact your tyre manufacturer.
• For tyre fitting instructions consult the relevant tyre manufacturer.
Do not use latex inner tubes with rim brake rims. Excessive heat generated from braking may cause a latex tube to fail and deflate which may result in serious injury or death.
• Never exceed the maximum pressure stated for your tyre or your wheelset.
• Use only plastic tyre levers.
• We recommend that safety glasses are worn whilst fitting and inflating tyres.
INSPECTING & LOOKING AFTER YOUR HUNT BIKE WHEELS
Wear and tear of components in your Hunt Bike Wheels will occur as a result of normal use. If not attended to then these components may fail in use with a risk of serious or fatal injury. You should check the following regularly, and at least once per month or every 500 miles/800 km (whichever is sooner). If using your bike in wet weather or off-road, then check your wheels at least every week or every 100 miles/160 km (whichever is sooner):
• For aluminium rim brake wheelsets check that the wear dot indicators on your rims are still visible. If this wear dot disappears then the brake track has become worn out and you should discontinue using the wheels immediately. (Top tip – when you notice that the wear dot is becoming smaller you can use the wheels on an indoor trainer where braking is not required as frequently but do not use once the wear dot has fully disappeared).
• Check that bearings are running smoothly without excessive resistance. A small amount of roughness is fine but if there is significant resistance this is an indication of excessive wear and the bearings should be replaced.
• Only replace bearings with spares provided by Hunt Bike Wheels and replacement should only be carried out by a qualified cycle mechanic. Wheels can also be returned to Hunt Bike Wheels for bearing replacement.*
• Check that spokes and nipples have not come loose.
• Check for any signs of damage to any of the wheel components in particular at the rim bed where the spokes are attached and on the spoke nipples.
• Check for trueness and roundness. If your wheel appears to be out of true, then please refer to a qualified cycle mechanic. Wheels can also be returned to Hunt Bike Wheels to be re-trued.*
• Check the freehub mechanism is engaging correctly, and clean and lubricate if necessary www.huntbikewheels.com for instructions.
• Check for wear on your brake pads. If your wheel is provided with brake pads check the user guides for these at www.huntbikewheels.com
• For carbon rim brake wheelsets check the braking track for wear or loose fibres. If the braking track is worn or loose fibres are showing discontinue use immediately.
• Check threaded axle adaptors/axles are correctly tightened.
• Only use Hunt Bike Wheels rim tape.
• Regularly inspect the tape for damage such as cuts or severe bowing into the spoke holes.
• Replace the tape annually or whenever showing sign of degradation, deformation or wear.
• Every bicycle component has a finite useful life. Bicycle wheels are subject to wear and stress in use. Different materials and components wear or fatigue from stress at different rates with different life cycles 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 exceeded, the component can suddenly and catastrophically fail without warning, causing serious injury or death to the rider. You must frequently inspect components for any signs of wear or fatigue. If you have any queries, always consult a qualified cycle mechanic or contact us using the details at www.huntbikewheels.com. Scratches, cracks, bending, fraying or discolouration are all signs of stress-caused fatigue and may indicate that a component is at the end of its useful life and needs to be replaced. When you see any of these signs, please stop using your wheels and take them to a qualified cycle mechanic for inspection, repair or replacement as necessary. Products may also be returned to Hunt Bike Wheels for inspection*
• Road salt can accelerate corrosion of metal parts. It is important that any road salt residue is cleaned off as soon as possible.
• While the materials and workmanship of your wheels may be covered by a warranty for a specified duration, this is not a guarantee that the product will last the term of the warranty without failure. The warranty is not meant to 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.
Broken spokes are reasonably rare but can happen from time to time as a part of normal wear and tear. You can purchase replacement spokes & nipples for all HUNT wheelsets to allow a qualified mechanic to replace a broken spoke easily.
CARBON UD SPOKES
The technology used with our carbon spoked UD wheels requires a different approach to truing and tensioning the wheels. It is important to understand the construction and use the correct technique otherwise damage may occur.
At the hub end of the spoke an aluminium mandrel is placed around the spoke during the curing process and is pulled tight against the (tapered) head of the spoke. The rim end of the spoke is fitted in the same way with a threaded steel mandrel. The steel mandrel has a standard square outer shape, but it is not a conventional spoke nipple.
The square section of the steel mandrel is essentially part of the spoke. The square sectioned mandrel needs to be used to hold the spoke stationary, to prevent twist whilst adjustments are made to the internal nut/nipple.
The nut/nipple must be accessed from the tyre side of the rim. The tyre and tube (if fitted), as well as the rim tape will need to be removed to access the nipple.
The rim tape should be replaced after the truing/tensioning process.
Failure to hold the spoke at the steel square sectioned mandrel is likely to twist and damage the spoke. This could cause a failure of a spoke or spokes. Should any damage lead to a failure this could result in an accident that may cause injury or even death.
We recommend that any work required to UD spoked wheelsets is referred to us.
• Never clean your wheels using a pressure washer, this will damage bearings and reduce service life 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 fibre 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 (approx. 500 miles)
• You should also check your wheels carefully for damage after any accident or major impact such as running through a pot-hole
• If you are in any doubt about maintenance, inspection, repair or any other aspect of owning your Hunt Bike Wheels then you should contact a qualified cycle mechanic or get in touch with us using the details at www.huntbikewheels.com
BRAKE PADS & BRAKE SETUP
• Do not use latex inner tubes with rim brake rims. Excessive heat generated from braking may cause a latex tube to fail and deflate which may result in serious injury or death.
• Follow instructions provided by your bicycle or component manufacture when fitting brake pads and setting up brakes.
• Braking distances will be increased in wet weather, particularly with carbon braking surfaces. Reduce speed and brake earlier in wet weather.
• Check brake pad surfaces regularly for contamination by dirt, grease, oil or particles that may impair braking performance or damage braking surfaces.
• Check the brake pad wear indicator regularly and replace brake pads when required.
• Brake pads are supplied with all carbon rim brake wheels. Do not use any other brake pads with carbon rim brake wheels. Check the user guides at www.huntbikewheels.com. Replacements can also be ordered through www.huntbikewheels.com
• Never use a brake pad on a carbon rim if it has previously been used on an aluminium rim, the pads will have been contaminated by aluminium particles which will damage the carbon braking surface.
• Extended periods of braking may cause excessive heat to build up in your wheels. This can impair braking performance. With rim brake wheelsets this heat may also cause damage to your wheels or cause dramatically increased tyre pressure resulting in the failure of tyres and/or tubes with a risk of serious or fatal injury.
• Temperature build-up will be most severe in the circumstances below:
- Long and/or steep descents
- Riding on hot days
- Higher 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.
• Before commencing a long descent reduce your tyre pressure by 10psi/0.7 BAR vs your normal setting. This will reduce the risk of tyre failure as a result of excessive heat build-up.
DISC BRAKE ROTOR LOCKRINGS
Our latest disc brake rotor lockrings can be fitted and removed using two different tools. You can decide to use one or the other, or maybe have both available as a back-up.
The outer circumference of the lockring engages with a standard 16 notch external BB tool. With our older lockrings this interface was the only available option. These tools are widely available from all bicycle tool manufacturers. A good quality example would be Park-Tool’s BBT-69.2 tool. The BBT-69.2 mounts onto a 3/8” ratchet so you can use a torque wrench to make sure you have achieved the recommended torque of 40nm. Many other variations are available, including those with their own handles, although of course this makes it impossible to verify torque so cannot wholeheartedly recommend these.
On our latest lockrings only, the inner circumference engages with a Shimano TL-LR11 tool. This tool has spanner flats, but ideally should be used with a ratchet/torque wrench. Whilst this isn’t the most common tool (it differs from a visually similar regular cassette lockring tool to give increased clearance), it is sometimes useful to have another option should the outer circumference become damaged.
Previously wheelsets used to come complete with an ultra-low profile lockring and a standard lockring. The ultra-low profile lockring is designed to be fitted to the front wheel as on some bikes clearance can be tight between the fork and the lockring. If you have these lockrings please ensure that the ultra-low profile lockring is mounted to the front wheel.
Our new low profile lockrings are thinner than our previous lockrings supplied with rear wheels so come fitted front and rear. These give sufficient clearance on almost all bikes.
If you are having clearance issues, contact us so that we can supply you with an ultra-low profile lockring.
Whichever lockrings you use, always make sure that there is sufficient clearance and that the recommended tightening torque is followed. Failure to adhere to this could cause the lockring to fail or come loose which could cause an accident resulting in injury or even death.
IMPACT DAMAGE, POTHOLES, ACCIDENTS & HARD RIDING
Hunt Bike Wheels are designed to have a high strength to weight ratio and pass our stringent rolling road, impact and real-life road tests, but they aren’t indestructible. Certain impacts of sufficient severity will damage and or destroy a bicycle wheel. These impacts include those from sharp or square edges such as from a pothole and high energy impacts, such as from an accident or heavy landing, especially if the wheel is impacted from the side.
• HUNT rims can be damaged through impact/s by rocks, potholes and other road and trail obstacles. This damage is not covered under our warranty, but we will be happy to help. Email or call us and we will work to get your wheels fixed at a reduced cost to you as part of our crash replacement policy.
• Excessive force or the improper use of tyre levers during tyre installation or removal can dent and damage both carbon and aluminium rims, this damage is not covered under warranty.
• Crashing your bike can exert forces upon a wheel much higher than experienced through normal riding. This can result in damage to the wheel components which could render them unsafe to use. Even if no damage is initially visible the wheels should be thoroughly inspected after an accident by a qualified and experienced cycle mechanic or us before the wheels are ridden again. If a component of your wheel is damaged, we will happily put this right at a reduced cost to you as part of our crash replacement policy – please email or phone us for details.
• Any accidental damage is not covered under warranty, but if something has happened, get in touch and we will see if we can help.
• Products should not be used outside their recommended usage. For instance, wheels designated for road use should not be used off road. 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 serious injury or death to occur.
• Regularly riding near to a wheelset’s limits will fatigue and shorten the lifespan of the product. We recommend that if a wheelset is being ridden in this manner that it is inspected on a more regular basis.
We design our wheelsets as a system built up of various components optimised to work together, but our rims are available separately. If you choose to build or have our rims built into wheels, of course, we cannot carry out the stringent testing that we put our wheelsets through. However, here are, in addition to the rest of this manual, our recommendations to help ensure your rims build up into a safe wheelset.
• Make sure that whoever builds your wheel/s is a suitably qualified and experienced wheel builder.
• Abide by the recommended spoke tensions and lacing patterns as listed on the rim product page of the Hunt Bike Wheels website.
• Nipple washers must be used when building our carbon rims.
*Charges may apply for maintenance work, but we will always confirm these with you before any work is carried out.
