This Fulcrum SPEED 55T Carbon Tubular Wheelset is no longer available although you may find similar or newer versions below:
The Fulcrum Speed 55T road wheelset is designed to maximize speed, while keeping the weight down and maintaining strength. Using a 55mm Carbon tubular rim laced up to a pair of light weight carbon hubs these are an unbelievable wheelset at a great price.
|Front Axle Type:||Unknown|
|Wheel Size:||700c (622)|
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.
There is a huge Italian tradition of cycle engineering excellence and Fulcrum was born from the very heart of it. Competition testing with world level athletes and the expertise Fulcrum's engineers possess means Fulcrum have become known for developing unsurpassed products with excellent performance, durability and market leading innovation. Key technologies pioneered by Fulcrum include 2:1 Two-to-One™ Spoke Ratio, which delivers incredible power transfer by doubling the spokes on the critical drive side of the wheels so no energy is wasted. Fulcrum has also focused on class leading rolling resistance through their CULT and USB Bearing Technologies which use ceramic bearings and cutting edge surface technology to massively reduce friction. CULT ball bearings are 9 times smoother than wheels with traditional bearings. All this innovation and technology has produced amazing results for everyday riders and pros alike with 4 world champions in just 6 years, Boonen, Bettini (x2) and Ballan.
