Fulcrum Speed 40 DB disc Wheels - Black

Fulcrum Speed ​​40T DB disc wheels. We could start from the new design of the circle, to describe SPEED 40T DB, that wide-nose profile that optimizes aerodynamic flows to save every small watt and make driving easier with crosswinds. In the same way, we could do this by talking about the record-breaking rigidity of the spoke-hub sector, supported by the oversize flanges and the Two-to-one, which allow despite the low number of spokes, and therefore less weight, to eliminate flexing during shots and countermeasures.
But, perhaps, it would be the case to leave space to the road, to the moments in which one is on the edge of the out-of-bounds in the group, when months and months of training are ready to assert themselves on the asphalt. SPEED 40T DB is designed for this, for those who want to race and strive to improve race by race, and we prefer to define it this way: the ideal wheel to show up on the grid, suitable for mixed routes, light uphill, stable downhill, rigid and comfortable for long days of competition where you need every single watt and the lucidity to manage yourself at best. Not only technology, but also character, because this is a carbon wheel that strikes from the first meters, even without knowing it thoroughly. A matter of sensations. Numbers in hand, impressions are confirmed by technical data, an example among all: the full carbon hubs and rim system for tubular with the new layers of “longitudinal twill” transfers the impressed power even better with an increase of about 10% compared to to the previous models.
