The top-of-the-range SONIQ ALX model is a concentrate of technology and design. The 6082 welded aluminum rim with T-6 heat treatment has an undrilled bridge, which ensures increased rigidity and strength and makes the rim tape unnecessary for tubeless mounting. The medium-height rim with a 33 mm profile and a modern 23 mm wide inner channel is suitable for 30 mm tires and more.
The extra highlights are the CNC Square-Milling machining on the top of the rim, sandblasted finish, laser engraved graphics and chrome color bonding details. Aero triple-conification rays are radiated according to Fulcrum's 2:1 model, which optimizes power transmission. The hub with full axle and adjustable bearing preload system ensures smooth operation and long service life. The total weight is only 1.745g.
