The latest generation of the Fulcrum Wind mid-priced aero carbon wheels has increased slightly in depth, with the Wind 42 replacing the Wind 40 and the Wind 57 replacing the Wind 55.
In line with modern trends, the internal rim width has also increased from 19mm to 23mm, with a 29mm external width, to better support wider tyres. Fulcrum says that the new Wind wheels are designed for light off-road use, so that they’re an option for less technical gravel and all-road riding as well as on-road use.
Fulcrum recommends the use of tyres from 28mm to 30mm wide for road use and between 32mm and 35mm wide for all-road use, although it says that the rims can be used with tyres anywhere from 25mm to 45mm wide. Fulcrum continues to use a hooked bead profile.
It says that it has also trickled down tech from its top spec Speed wheel family, itself updated in May. The new Wind wheels have the same rim depths and profiles as the Speed and a wider radius nose than the previous generation Wind wheels, which Fulcrum says improves aerodynamics.
It claims that this has resulted in a 22% improvement in handling and 10% improvement in reactivity, based on a formula it has developed that takes account of flexing and energy dissipation during changes of direction.
Although the rims are wider and deeper than the old Wind rims, Fulcrum says that their weight has been reduced too, as a result of a new carbon fibre mix and lay-up, although these still differ from those of the Speed wheel family. It claims that this has allowed it to save around 100g per wheelset, with a claimed weight for the Wind 42 of 1,510g and for the Wind 57 of 1,585g.
More carried-over wheel tech
Fulcrum has carried over its other tech into the new Wind wheels, including its patented DRSC system, which adds a plastic support within the rim which it claims increases stiffness and durability and improves the distribution of stresses in the rim. It says that it also helps guard against galvanic corrosion between the rim and the spokes.
It continues to use its Two-Way Fit sealed rim bed, which doesn’t need taping and can be used both tubeless and with tubes. The internal surface of the rim is polished for easier tubeless set-up, while the matt outer surface incorporates laser-etched graphics as well as reflective stickers.
