Carbon-Ti is pleased to announce the birth of a new major collaboration with the French company Duke Racing Wheels by Philippe Jacquinet. 

Duke Racing Wheels produces high-tech carbon fiber rims, and supply them to multi-titled professional teams for years.

The collaboration foresees the furnishing of the latest generation of MTB, Road, and Gravel wheels to offer a complete range of Carbon-Ti wheels.

We entrusted Pippowheels, the leading company in this sector, that is making available experience, expertise, and equipment for the realization of high-quality wheels.



Sapim CX-Ray rays have been chosen for all the fittings to guarantee maximum performance, and for the ease of finding spare parts.

We will supply the wheels with the latest 100% made-in-Italy Carbon-Ti Straight Pull hubs.

The new version includes mechanical parts subjected to a special surface hardening treatment. The mechanics boast SKF-sealed bearings of the highest quality and a preload adjustment that ensures an always optimal setup. Demanding customers who don't want to compromise can opt for the special Ceramic Speed option on any wheel.

Mtb wheels are fitted out as standard with six holes disk attack matte blacks hubs. Nevertheless, it is possible to have on request different anodized colors for them. Warning: These options may require longer waiting times. The customization of the wheels is completed by choosing the colored decals applied to the rims.


Decal kits colours (optional): black, silver, white, mirror gloss (chrome), gold, red, blue
