The Black Inc. Sixty Track Tubular Wheelset is built for track cyclists seeking maximum power transfer and responsiveness. Optimized for 23mm tires, it features an exceptionally stiff carbon rim constructed with Black Inc.s strongest layup to handle the extreme torque of sprinting and bunch racing. The 20-spoke front and 24-spoke rear use Pillar Wing 22 bladed and butted steel spokes, which are 30 percent stronger than standard lightweight spokes to enhance lateral, vertical, and torsional strength. The high-flange J-bend hub shell increases bracing angles for improved stability, while durable brass nipples add longevity. Designed for a 100mm x 12mm thru-axle front and a 120mm threaded bolt rear hub, the Sixty Track Tubular wheelset delivers a balance of strength, aerodynamics, and sleek aesthetics for serious track riders.
