SPEED 40T DB is designed for this, for those wanting to race who commit to improving one race after another. We prefer to describe it like this: the ideal wheel for bikes on the grid, suitable for mixed trails, lightweight uphill, stable downhill, stiff and comfortable for long days of racing when every single watt counts, together with the lucidity for best management.
The new rim design of the SPEED 40T DB, with a wide nose profile that optimizes aerodynamic flows to save every single watt for easier, more efficient riding in crosswinds along with record stiffness of the spoke-hub section, supported by the oversize flanges and the Two-to-one that, despite the lower number of spokes and therefore lighter weight, enable elimination of bending during attacks and counter-attacks.
But perhaps the best thing would be to let the road speak for itself, those moments when the group is riding at the edge of its aerobic threshold when months and months of training are ready to bring results on the asphalt.
Not only technology but also character, because this is a carbon wheel that makes its mark right from the start, even without in-depth analysis. Based on available figures, impressions are confirmed by technical data and one example of many is the full-carbon hub and rim for tubular tires with the new layers of “longitudinal twill” transfer the force applied even better with an increase of about 10% compared to previous models.
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.
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension.
This results in undesirable flex of the whole wheel and an unavoidable loss of energy. Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.
A system that is as simple as it is effective, the result of the ingenuity of Fulcrum® engineers and attentive observation of the results of the tests performed on the wheels on a daily basis.
These tests made it possible to understand that the forces that act on the sides of the wheels, and therefore on the spokes, are extremely different; but what’s more, the differences between the front and rear wheels are also evident and significant. The front wheel, in fact, has to remain stable even during braking of the disk on the left side, and the rear wheel, in addition to the sprocket set, has to compensate for the traction of the force on the chain side.
Exclusive rim/spoke coupling system. It allows the rim, spokes, nipples and hub to align properly with the same tensioning value in all areas.
What is MoMag™?
A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag™.
Right from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”.
Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company.
Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum® makes every day to give you maximum performance and reliability.
A guarantee of quality
The keyword for our products is: traceable.
If you find a little label attached to any Fulcrum® product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable.
All this because, devoted to its mission, Fulcrum® demands the absolute perfection and safety for its customers.
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.
Fulcrum®’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular.
This ensures stability, excellent handling and superior comfort.
No holes on the bridge connector means that the rim is uniform at every point, free from critical areas subject to stress.
The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.
The Plasma treatment makes the aluminium especially hard and resistant to surface abrasion and wear. This has allowed thickness of materials to be reduced to a minimum, achieving advantages of lighter weight, while maintaining lifespan and reliability.
The rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum®’s R&D department found itself facing a fundamental choice: on which side to put the oversize flange of the Two-to-one™ system? Disc or sprocket side? Without question - must stay on the sprocket side.
To combat the loss of braking power from flex and torque of the connector between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs.
