No.6 Pulsar Disc A3RO Tri-Spoke Rear Wheel

The No.6 Pulsar Disc A3RO Tri-Spoke Rear Wheel is engineered for riders seeking maximum aerodynamic performance in time trials, triathlons, and high-speed racing applications.

Developed under the ProjectSpeed philosophy, the A3RO is designed to minimise drag, optimise airflow, and maximise energy efficiency when speeds are high and every watt counts. The distinctive tri-spoke construction delivers exceptional aerodynamic performance while creating a striking visual presence that stands apart from conventional wheel designs.

With a deep 76 mm aerodynamic profile, the A3RO is built to maintain momentum and convert power into forward speed with maximum efficiency. Constructed from premium Toray T800 and T1000 carbon fibre, it delivers exceptional stiffness and direct power transfer, making it ideally suited to sustained high-speed efforts.

At the heart of the wheel is the latest No.6 Zero Gravity V3 rear hub, featuring premium TriPeak ceramic bearings and the No.6 Vapour 45T ratchet system for rapid engagement, reduced rolling resistance, and dependable performance under race conditions.

Whether you're targeting a personal best, chasing podium results, or building the ultimate triathlon or time trial machine, the A3RO is designed for one purpose: speed.
