The SONIQ GR rear wheel was designed to provide maximum efficiency, stability and power transmission in gravel. The 2-WAVE rim, with a flange width of 30 mm and a mini-hook, harmonizes perfectly with tires from 47 to 50 mm wide and guarantees traction optimal. The variable profile of 47/52 mm reduces air resistance and improves aerodynamics. Made of FF80 carbon, this rear wheel offers a perfect balance between rigidity, weight and robustness. High-end hubs equipped with waterproof industrial bearings and sturdy spokes ensure reliable performance, ideal for fast gravel racing and challenging adventures.
