Fulcrum Soniq ALX C23 Wheelset - 28" | Aluminium | 2-Way Fit | AFS - 12x100mm | 12x142mm - SRAM XDR

The excellence of aluminum

The flagship model, Soniq ALX, is a combination of technology and design. The welded rim made of 6082 aluminum with T-6 treatment features a non-drilled bridge, ensuring greater stiffness and strength, and eliminating the need for tape for tubeless setup. The medium-profile rim of 33mm, with a wide and modern 23mm internal channel, is suitable for tires from 30mm and up.

Additionally, the wheel features CNC Square Milling machining on the upper surface, sandblasted finish, laser-etched graphics, and chrome adhesive details. The flat, triple-butted spokes, arranged in Fulcrum's 2:1 pattern, optimize power transmission. The hub with integrated axle and adjustable bearing preload ensures smoothness and durability. All this at just 1.745g. 

Technologies of Fulcrum Soniq ALX C23 wheelset

High strength Aluminum | Special aluminum - the best aluminium wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum® R&D uses only the best aluminium alloy 6082, with artificial ageing T6 temper that stabilises the alloy and gives it maximum life and reliability.
Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.

2:1 Two-to-One Spoke Ratio™ - Disc Brake | 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.

F.I.C. Fulcrum Identification Card - 100% HANDMADE QUALITY | 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.
