Fulcrum spent hours and hours in wind tunnels. They studied the effects of rolling on the structure of the rim to make a wheel dedicated to the very essence of speed, when average speeds are really high and every watt has to count. The new 55 mm design is the latest response to the historic challenge of headwinds and attrition.
Full carbon Fulcrum® rims are built using combinations, developed in the laboratory, of different types of fibre, including UD and the famous 90-degree 3K of models at the top of our range.
To build them we developed a special HTG (high transition grade) resin, whose glass transition point is at a higher temperature than any other fibre used in the bicycle industry.
This gives incomparable performance when braking.
In line with their aim to save every possible gram of weight and to choose the most advanced technological solutions, the R&D department has developed a seamless carbon hub.
The fibre selected is woven at 90 degrees, for enhanced balance of torque when pedalling.
Behind this project is the exclusiveness of Cronitect® steel, using “Advanced by FAG” technology by Schaeffler Group employed for the bearing races. This steel is resistent to the corrosion of the highest level until the point that no grease is necessary for lubrication, maybe just a small amount of oil.
The top quality ceramic balls, thanks to the absence of lubricating grease and the precision machine of the cup and cone technology, allow to reduce the friction coefficient drastically and then increase the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings.
An outstanding result achieved by using cutting-edge technologies in the field of materials processing.
