Technical questions

Why do you use 24 spokes on the back wheel ?

After trials with different spoke and hub design, the 24 spokes wheel offered the best rigidity and integrity relative to the wheel weight .

What is the best tyre pressure for ZeroCx wheels?

For tubular wheels the pressure is specified by the particular brand and make used. For cover wheels, we recommend staying below a maximum of 8 bars.

Is there a recommended weight limit for ZeroCx wheels?

ZeroCx wheels are configured for maximum efficiency in any typing of cycling, be it competitive or touring. Nevertheless, the wheels provide best efficiency for cyclists of upto 100Kg (=220 lbs), we do not recommend ZeroCx for cyclists of this weight.

What tension does ZeroCx apply to the spokes?

The wheel build does not use spoke tension as a lead parameter, rather the wheels are configured for best balance, so spoke tension can vary on the same wheel. In spite of varying tensions, the wheel will provide a perfect balance and behaviour.

How do I choose the wheel cover width?

ZeroCx recommends tubular or cover width of 21 to 23 mm for best versatility and performance.

Why do you use 3K carbon layer ?

3K carbon layer refers to the interweaving type and weight per square centimetre of the carbon used. The leading properties for 3K carbon are lightness, rigidity and good dynamic absorption.

Tubular or Cover wheels?

Opinions vary, but our experience with cycling has been that triathletes use covers since they are easier to fix in case of puncture and road cyclists use tubular wheels since puncture replacement is often not a problem during races. Tastes vary widely though, and comes done to personal preference.

Almost all ZeroCx wheels have a 100% carbon braking band. But since 2014 ZeroCx now is selling a new model of Zero Rival (52/52mm) super light wheels with alloy braking band.

A. Preparation stage of the rim (time required: 48h) => Essential steps that only have to be made once before gluing the tubular tire (Stage B)

1. Slightly mill the valve hole with a scraper so that the tubular tire fits the shape of the hole.
2. Energetically sand the rim with very fin abrasive paper.
3. Apply a soft cloth soaked in solvent (= universal resin thinner) to clean and degrease it.
4. With a paintbrush, apply a first layer (as evenly as possible) of tubular glue on the rim.
5. Let the tire dry at least 24 hours.
6. With a paintbrush, apply a second layer (as evenly as possible) of tubular glue on the rim.
7. Let the tire dry at least 24 hours.

B. Gluing the tubular tire on the rim (time required: 24h) => Necessary steps for each change of tubular tire:

1. Pump the tubular tire to 3 Bars.
2. Coat the tubular tire with tubular glue.
3. Once the tubular tire is dry, apply a third and last layer of glue.
4. Clean both sides of the rim in order to remove any tubular glue residue.
5. Quickly place the tubular tire on the rim, starting by placing the valve upright into the valve hole.
6. Strech the tubular tire to place it properly on the rim. Movement from the top to the bottom.
7. Pump the tubular tire to 10 Bars.
8. Put the tubular tire on the rim and center it with your thumbs.
9. Press the tubular tire against the rim with your body weight, doing pendular movements, so that the tubular tire touches the rim and sticks evenly.
