No.6 Pulsar Disc + A3RO Tri-Spoke Wheelset

Maximum Aero. Built for the Clock.
 

The No.6 Pulsar Disc + A3RO Tri-Spoke Wheelset combines No.6 Racing Wheels' fastest rear wheel with the aerodynamic 76mm A3RO Tri-Spoke front, creating a purpose-built wheelset for time trial and triathlon racing.

At the rear, the Pulsar Disc is engineered for maximum aerodynamic efficiency, smoothing airflow and maintaining momentum during sustained high-speed efforts. Up front, the A3RO Tri-Spoke combines a deep 76mm profile with an aerodynamic three-spoke carbon construction designed to reduce drag while delivering the distinctive feel and presence of a dedicated TT wheel. Together, they create a no-compromise race setup for riders chasing speed against the clock.

Pulsar Disc Rear

The Pulsar represents the most aerodynamic expression of the No.6 ProjectSpeed philosophy.

Its full carbon disc construction is designed to reduce drag, stabilise airflow and maximise energy efficiency at speed. The wide 25mm internal / 30mm external hooked profile is optimised around modern 28–30mm tyres and is fully tubeless ready.

At just 890–910 g, the Pulsar combines full-disc aerodynamic performance with impressively low weight.

A3RO Tri-Spoke Front

The A3RO Tri-Spoke completes the package with a distinctive 76mm aerodynamic profile.

Its three-spoke carbon construction is designed to smooth airflow and reduce drag across high-speed efforts, making it particularly suited to time trials and triathlons where aerodynamic efficiency is paramount.

The front wheel weighs 907 g and features a modern 25mm internal / 32mm external width, optimised for 28–30mm tyres.

 

Both wheels use Toray T800/T1000 carbon, a UD glossy paintless finish and hooked tubeless-ready profiles.

The combination gives riders a contemporary TT setup built around modern tyre widths rather than the narrow tyres traditionally associated with disc and tri-spoke wheels. Both wheels are optimised for 28–30mm tyres and carry a 110kg rider weight limit.

Freehub Options

The Pulsar Disc rear wheel is available with a choice of:

All freehub options use the No.6 Zero Gravity V.3 hub system, Vapor 45T engagement and Tripeak ceramic bearings.

Key Features

Specifications are based on No.6's current A3RO and Pulsar product information.

What's Included?

The combination is specifically designed for time trial and triathlon racing, pairing the aerodynamic A3RO Tri-Spoke front with the full Pulsar Disc rear for maximum high-speed efficiency.

The A3RO front wheel has a 76mm profile, with a 25mm internal and 32mm external width.

The A3RO front weighs 907 g, while the Pulsar Disc rear weighs approximately 890–910 g, giving a combined wheelset weight of approximately 1,797–1,817 g.

Both wheels are optimised for 28–30mm tyres and are tubeless ready.

The Pulsar Disc rear can be ordered with Shimano HG 11/12-speed, SRAM XDR, Campagnolo N3W or Shimano Microspline freehubs.
