Featuring a welded 6082-T6 aluminium rim, wide internal profile and Fulcrum’s proven spoke geometry, the Soniq ALX offers performance and reliability that rivals carbon alternatives.

Advanced Rim Construction

The Soniq ALX uses a welded, non-drilled rim with a 6082 aluminium alloy and T-6 heat treatment. This increases durability and stiffness while eliminating the need for rim tape when running tubeless tyres. The 33mm medium-profile rim is optimised for tyres from 30mm and wider, improving ride comfort and control on long or mixed-surface rides.

Premium Design & Finish

With a sandblasted finish, laser-etched graphics and chrome-effect adhesive details, the Soniq ALX delivers a distinctive, high-end look inspired by Fulcrum’s flagship wheelsets.

High-Performance Hubs & Spokes

The aluminium hubs feature an integrated axle and adjustable bearing preload for long-term smoothness and reliability. Flat, triple-butted aero spokes in a 2:1 lacing pattern improve stiffness and power transfer, ensuring efficient performance under load. The Centre Lock disc interface guarantees consistent braking in all weather conditions.
