Specific nipple housing

Such a small part, yet so important. The nipples and their housing are one of the most important element that are taken into account during the design of a wheel.
During the development of the new E-Mtb Fulcrum rims, a lot of work was put into this aspect. The housing has been re-designed and now it makes it possible to eliminate completely the nipples' hard work.
Thanks to a special housing, with side guides on both sides, the nipple sets on a stable base, perfectly in position, oriented towards the spoke.
This makes it possible to make the distribution of the tensions in the rim more even, creating thus perceptible benefits in terms of effort and rigidity: this prevents misalignments under stress and, as a consequence, deformation to the structure.
