One year after introducing the Shark 42, the revolutionary profile can be found on the new Soniq 42 wheelset as well. The unique rim shape is the result of a long development process. The outcome is a characteristic 2-wave rim profile showing a symmetrical wave on the rim nose leading to an asymmetrical wave on the rim wall. According to Fulcrum this rim profile optimizes aerodynamics and stability. Rim height varies between 42 and 47 mm, following a wavy shape that adds to these attributes.

With this design, Fulcrum achieves an optimum balance between low air resistance and stable handling in crosswinds. Compared to a conventional profile with the same height, an improvement in crosswind stability of 21 percent was achieved in the wind tunnel with wind angles between 0° and 10° and even up to 30 percent at wind angles between 10° and 20°.

With an inner rim width of 25 millimetres and an outer width of 29.8 millimetres, the Soniq 42 is the perfect choice for road, all-road and gravel tires from 29 millimetres wide. The rims have a mini-hook for a secure fit with tubeless and tube-type tires. Thanks to the closed, undrilled rim bed, no tape is required for tubeless mounting. Fulcrum developed the patented MoMag system to guide spokes into place using a magnet. That makes spoking and centering possible as usual, despite the closed rim base.

Other features are the proven 2:1 spoking pattern using 2x the number of straight aerospokes on the freewheel side to better distribute forces and the use of industrial bearings in the aluminium hubs.
