PERMITTED TIRE SIZES AND PRESSURES

Tubeless system:

  • Minimum tyre size:25mm
  • Maximum tyre size:34mm
  • Maximum tyre pressure: 80psi / 5.5bar / 550kPa

Tube (clincher) system:

  • Minimum tyre size:25mm
  • Maximum tyre size:34mm
  • Maximum tyre pressure:101.5psi / 7bar / 700kPa

The shape of the R-Series rim is aero optimised for 25mm front tyre, paired with 28mm rear tyre, but we identify this size suiting smaller riders. Therefore, recommended tire sizes for R-Series wheels is bracketed by two weight categories:

For riders weighing <70kg (<155lbs) 25mm front tyre, paired with 28mm rear tyre

For riders weighing >70kg (>155ibs) 28mm front tyre, paired with 30mm rear tyre.

Please observe the maximum tyre pressure! Failure to do so could result in fatal or serious injury. This wheel system has been developed to support the latest in tubeless technology, centred around sizes 25-34mm. Tire manufacturers recommendations should also be taken into consideration, but the user should always be limited by the lower value.

Any use other than the intended use can lead to accidents resulting in serious injury or fatality. The partington.cc R39/44 Wheelset is designed solely for:

  • Installation on disc brake specific road bicycles using 12mm threaded through axles.
  • For use on sealed, paved or asphalt surfaces.
  • For installation of 700c clincher or tubeless specific tyres that comply with European Tyre & Rim Technical Organisation standards.
BASIC PRECAUTIONS > RIDING

Riding a bicycle always involves potential danger to both the rider and others around. Even with the proper use of approved safety devices and equipment, accidents resulting in injury or death can occur. Acknowledge these risks and be conscious of these risks and ride within the ability of yourself and those around you. Do not overestimate your technical ability!

Risk of accident through damaged wheels

Avoid riding through potholes, over curbs, steps, rough edges or compromised road surfaces. Check your wheels regularly for damage — particularly the outer perimeter of the rim which is most susceptible to impact damage. If any dents, cracks, large areas of abrasion or other abnormalities are present, then contact us direct at: contact.us@partington.com.au to arrange an inspection.

Never ride damaged wheels. Do not continue to use your bike after a serious crash, before getting the whole bike inspected by the respective manufacturers and receiving conformation that your equipment is without damage, and safe to use.

BASIC PRECAUTIONS > CARE

Be aware of your own technical ability. The hubs are the only serviceable part(s) outside of the factory, but even here, good technical competence and prior experience is essential. Follow only partington.cc service instructions. Servicing the hubs inside warranty should only be completed by a partington.cc approved Partner.

Clean and inspect wheels regularly. Clean with only light detergents. For more stubborn residues such as tar, the frugal use of isopropyl alcohol is permitted. Never use a pressure washer or steam system to clean your wheels. Use light dedicated bicycle cleaning detergents only. Ensure the disc brake rotors are not contaminated during any cleaning. If in doubt, source a dedicated disc brake cleaning product from your local bike store.

STORAGE & TRANSPORT

Your wheels are designed to be exceptionally strong in-service for as-intended use. However, they are still vulnerable to abuse and improper storage. The sidewalls of the rim are of highly-ordered carbon fibre, but very thin (~0.2mm at its thinnest) and supported by a structural foam material. This offers a high-performance solution for its intended application but is vulnerable to point loads and contact damage. When transporting or storing your bike/wheels, ensure suitable padding is used to provide a soft interface and an even distribution of load. If packing wheels side-by-side, avoid contact or penetration of the spaces between the spokes by the disc rotor, free-hub or cassette bodies. Such interference will likely cause damage to the spokes. Do not store your wheels with ambient temperatures above 60° Celsius.

Installing a cassette

The freehub body on your wheels can be changed in the event of a group set system change; i.e. from Shimano/SRAM 11s to SRAM XDR to Campagnolo and visa versa. Ensure that your cassette complies with the freehub body type of your rear wheel.

Shimano 11s freehub body can have a 10, 11 or 12 speed cassette installed but 10speed must be installed with a 1.9mm spacer provided with the cassette.

SRAM XDR freehub body is only suited to SRAM XDR cassettes.

Ensure your rear derailleur is properly adjusted and in good alignment. Particular attention should be made to ensure the derailleur does not interfere with the wheel spokes when shifted into the largest cassette sprocket. NOTICE! Ensure there is a minimum of 2mm clearance between the derailleur and closest spoke

Ensure your rear derailleur is properly adjusted and in good alignment. Particular attention should be made to ensure the derailleur does not interfere with the wheel spokes when shifted into the largest cassette sprocket. NOTICE! Ensure there is a minimum of 2mm clearance between the derailleur and closest spoke

INSTALLING DISC BRAKE ROTOR

Only use disc rotors from credible manufacturers

Only use ‘external drive’ type disc rotor lock rings

Follow the instructions from the manufacturer when installing your disc brake rotors Tighten to the manufacturers recommended tightening torque, but do not exceed 40 Nm!

Do not exceed the maximum tightening torque of 40 Nm

INSTALLING DISC BRAKE CALLIPERS

Ensure the proper rotor size and calliper mount is being installed.

Ensure the calliper is properly centered on the disc rotor. Retracting the pads fully will give best visibility of calliper centering

It is essential that proper installation is performed. Ensure there is a minimum of 2mm clearance between the brake calliper and closest spoke. Some variation in mating components (forks, callipers, and smaller disc rotors) may cause this clearance to become marginal. Please contact: contact.us@partington.com.au or your vendor if further support is required.

INSTALLING VALVE STEMS > TUBELESS

Your wheels have been optimised for tubeless use and will come with a tubeless valve stem assembled. This stem can be removed if the user wishes to install an inner tube as per traditional clincher format, however, please observe the following:

  • Use only the retaining nut supplied with the tubeless valve stem. Tighten only lightly by fingers.
  • Take care in both removal and re-installation of the valve stem and do not use any tools or implements to pry the valve stem or inner tube stem from the rim.
  • Use only supplied tubeless valve stems. Replacements are available by contacting sales@partington.com.au

Never exceed the maximum approved inflation pressure of either the wheel or tyre

INSTALLING TYRES > TUBELESS

Use only tubeless specific or tubeless ready tyres that are free from damage and/or excessive wear.

Never use tools or a tyre lever to mount the tyre onto the rim. We recommend the use of a quality approved tyre soap when installing tyres. Use only wide, flat plastic tyre levers to aid removal of the tyre. Do not use metal levers under any circumstances!

Use a dedicated tubeless pump to inflate and bead your tubeless tyre making certain that you do not exceed the maximum recommended tyre or wheel pressure. Tyre soap will aid the ‘seating’ of your tire if troublesome.

Once seated, release all pressure, and remove the valve stem core.

Inject 30-50ml of tyre sealant through the valve stem, then re-insert the valve stem core and inflate to ~3bar/40psi

Gyrate the wheel/tyre assembly to distribute the sealant throughout the interior of the rim and tyre. Effort should be made to bring sealant to the tyre bead rim interface to ensure a good seal.

Finally, continue inflating to your desired pressure.

Clean off any tyre sealant residue immediately.

INSTALLING TYRES > CLINCHER

Never exceed the maximum approved inflation pressure of either the wheel or the tyre.

Carefully remove the tubeless valve stem and store in a safe place. Retain the retaining nut to secure your inner tube stem.

Never use tools or a tyre lever to mount the tyre onto the rim. We recommend the use of a quality approved tyre soap when installing tyres. Use only wide, flat plastic tyre levers to aid removal of the tyre. Do not use metal levers under any circumstances!

Observe minimum and maximum pressures of both the tyre and the wheel. Follow only the highest minimum or lowest maximum described on both wheel and tyre together.
