Imagine the rim and tyre as a single unit composed of two materials. This is what we wanted to achieve conceptually with Ultra-Fit™ Tubeless technology. The rim was developed during the design stage to obtain perfect adherence with the tyre. The consequent elimination of friction makes it possible to improve performance considerably.

Energy dispersion is drastically reduced by the tubeless tyre. The advantages are indisputable even in terms of practicality. Fitting the tyre is facilitated by the form of the rim while two tracks in the rim groove help keep the type perfectly positioned at all times. Ultra-Fit™ Tubeless technology is used in Red Carbon™, Red Fire™, Red Zone™ XLR and Red Zone™ wheels.

Thanks to the rim profile design, ULTRA-FIT™ allows for perfect adherence between the tubeless tire and the rim.

The advantages of ULTRA-FIT™ technologies are:
- easy tire mounting
- maximum safety
- less friction
- less energy dispersion
- improved performance
