No.6 Pulsar Disc A3RO Tri-Spoke Wheelset

The No.6 Pulsar Disc A3RO Tri-Spoke Wheelset 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 deep 76 mm front and rear profiles, 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, the wheelset delivers exceptional stiffness, predictable handling, and direct power transfer, making it ideally suited to sustained high-speed efforts.

At the centre of the system are the latest No.6 Zero Gravity V3 hubs, featuring premium TriPeak ceramic bearings and the No.6 Vapour 45T ratchet system. Together they provide 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.
