TYRE RETENTION AND COMPATIBILITY

Like any modern tubeless system, the tolerances of the tyre bead diameter and hookless rim bead seat diameters must be carefully calibrated in order to create an airtight seal that will allow the tyre to stay on the rim and the rider to slow to a safe stop in case of puncture. If the tyre bead diameter is too large, it will not match the rim bead seat diameter. Likewise, if the bead material isn’t strong or stiff enough under high-pressure loads, the tyre bead will stretch over time and it will lose its original diameter. If rim manufacturers do not work directly with tyre manufacturers when designing new hookless rims, tolerances and bead materials can vary. This can make it difficult to pair tyres and hookless rims from different manufacturers.

WHAT SETS CADEX APART?

Rather than using a Kevlar-only bead, which can stretch over time and compromise the tyre bead diameter, CADEX tyres feature a carbon and Kevlar composite bead that’s strong enough to avoid stretching under heavy loads. This, combined with our accurately defined tyre and rim bead seat diameters, tested at pressures up to 150psi, guarantee dependable air and tyre retention.

What Tyres Can I Use?

CADEX components are built to be used as a system, and CADEX tyres are the best choice for use with CADEX WheelSystems on the road.

However, should you prefer to run a non-CADEX tyre, listed below are the tyres with an indicated maximum pressure above 72.5psi (5 bar) that have passed the CADEX test protocol for use with CADEX hookless rims. Please note that if the maximum pressure indicated for a tyre is 72.5psi (5 bar) or lower and the tyre is tubeless and hookless rim compatible as per the tyre brand or manufacturer's recommendation, it can be used with CADEX hookless WheelSystems and does not have to appear on the chart below:

Please note that if the maximum pressure indicated for a tyre is 72.5psi (5 bar) or lower and the tyre is tubeless and hookless rim compatible as per the tyre brand or manufacturer's recommendation, it can be used with CADEX hookless WheelSystems and does not have to appear on the ¨What Tyres Can I Use” chart.

*Please note that the Continental GP5000 S TR tire is apt for use on CADEX hookless WheelSystems and is a different tire from the previous generation Continental GP5000 TL tire. Please also note that as per Continental's specifications on rim inner width, the Continental GP5000 S TR in size 700x25C is only apt for use on the CADEX 42 and CADEX 42 Disc WheelSystems

**Please note that only the Pirelli Cinturato Velo tire with a maximum pressure of 72psi (5 bar) indicated on the tire sidewall is apt for use with CADEX hookless WheelSystems.

What Pressure Should I Run?

Appropriately inflated tyres conform better to imperfections in the road, absorbing impacts and allowing you to ride more efficiently and safely with more comfort and control. As mountain bikers have known for a long time, tyres that are inflated to a higher pressure than necessary for the terrain transmit more impacts and sacrifice speed, as well as energy, as the rider fights to keep the bike on track and to stop it from deflecting off obstacles, however small, in its path.

WHAT TYRES SHOULD I NOT USE?

For tyres that have failed the CADEX test protocol, CADEX is working with the tyre brands so updates can be made to make them ready for CADEX hookless rims as soon as possible.

Please be aware that if you choose to use a tyre with an indicated maximum pressure above 72.5psi (5 bar) that is not on the list of tyres that have passed the CADEX test protocol, YOU DO SO AT YOUR OWN RISK, as the tyre may not function properly with the CADEX hookless WheelSystem.

If the maximum pressure indicated on the sidewall of the tyre is below 72.5psi (5 bar) and the tyre is hookless rim compatible as per the tyre manufacturer’s recommendation, the tyre can be used with CADEX hookless WheelSystems and does not have to appear on the “WHAT tyreS CAN I USE?” chart.

Although CADEX tyres are designed for best use with a CADEX hookless rim, it is possible to use a CADEX tyre on a hooked bead rim.

If necessary, you may use an inner tube on a CADEX hookless rim, so long as the tyre you are using has passed the CADEX test protocol. However, please note that CADEX hookless rims are designed to perform best when set up as tubeless and used without an inner tube.
