The Super-9 Clincher Track Disc wheel, available front and rear, provides track racers exceptional stiffness, aero efficiency, rolling efficiency, power transfer, and light weight in a track wheel. In a significant evolution of track-wheel technology, the Super-9 Clincher Track Disc features a clincher rim designed specifically for the velodrome. The rim utilizes a small hook tire bead designed for aero efficiency. A track-specific carbon laminate adds stiffness to the wheel system. With a refined shape to be faster, the Super-9 Clincher Track Disc is the fastest with 23mm tires on the velodrome. The disc optimizes supreme aerodynamics, power transfer, stiffness, light weight, and durability. The wheel remains flat from its widest point to the hub and features a proprietary textured surface. The result is unmatched speed on the track available in front and rear variants. The Super-9 Clincher Track Disc wheels are made to order and will have a 90-day lead time from order.
