TIRE RETENTION AND COMPATIBILITY

Like any modern tubeless system, the tolerances of the tire bead diameter and hookless rim bead seat diameters must be carefully calibrated in order to create an airtight seal that will allow the tire to stay on the rim and the rider to slow to a safe stop in case of puncture. If the tire 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 tire bead will stretch over time and it will lose its original diameter.

If rim manufacturers do not work directly with tire manufacturers when designing new hookless rims, tolerances and bead materials can vary. This can make it difficult to pair tires 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 tire bead diameter, CADEX tires feature a carbon and Kevlar composite bead that’s strong enough to avoid stretching under heavy loads. This, combined with our accurately defined tire and rim bead seat diameters, tested at pressures up to 150psi, guarantee dependable air and tire retention.

What Tires Can I Use?

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

However, should you prefer to run a non-CADEX tire, listed below are the tires 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 tire is 72.5psi (5 bar) or lower and the tire is tubeless and hookless rim compatible as per the tire 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 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 apt for use only 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 tires 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, tires 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 TIRES SHOULD I NOT USE?

The following tires have either failed the CADEX test protocol or are indicated by the brand or manufacturer as being incompatible with hookless rims. They currently do not function properly with CADEX hookless rim WheelSystems:

Brand / ModelTire Sizes
700x24C700x25C700x26C700x28C700x30C700x31C700x32C

PIRELLI P ZERO RACE TLR SL
PIRELLI P ZERO RACE TLR
SPECIALIZED ROUBAIX PRO 2BLISS

VITTORIA RUBINO PRO TLR

For tires that have failed the CADEX test protocol, CADEX is working with the tire 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 tire with an indicated maximum pressure above 72.5psi (5 bar) that is not on the list of tires that have passed the CADEX test protocol, YOU DO SO AT YOUR OWN RISK, as the tire may not function properly with the CADEX hookless WheelSystem.

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

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

If necessary, you may use an inner tube on a CADEX hookless rim, so long as the tire 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.
