What is ProjectSpeed™
Every watt, accounted for.
ProjectSpeed™ is No.6's wheel development platform. Rim profile, carbon layup, internal width and tyre fit are designed together, as one system, then tested until the numbers hold up. In the wind tunnel, in the lab and in the race. Not in isolation, and never on paper alone.
The range
Eight wheelsets. One platform.
Every No.6 wheel is developed through ProjectSpeed, from the 28mm climbing wheel to the full disc. Same process, tuned for different riding.

The wind tunnel
Rim and tyre measured together, across yaw angles and race speeds.
The lab
Fatigue, impact and stiffness testing on every new design.
The road
Raced by our riders, who tell us what the data can't.
01 · The wind tunnel
We test our wheels against the benchmarks, not against each other. Our TT setup, the Pulsar Disc with the A3RO Tri-spoke, was faster than a Scope and Bontrager setup at every yaw angle tested. The same thinking runs through every profile in the range, from the 28mm climbing rim to the full disc: rim and tyre designed as one system.
Tested against the best. Not each other.
03 · The lab
Every new design starts in the lab, where testing happens in two layers: performance testing, then repeated quality control. Each test feeds our data. We use it to predict how a wheel will behave and perform, and to set the carbon layup and spoke tension before a single wheel is built. CFD modelling adds another layer of data points. Test samples then go to the wind tunnel and out onto the road, and what we learn there comes straight back to the lab. Then the cycle starts again, so every ProjectSpeed™ wheel keeps improving. The test samples never leave the lab: the wheelset you receive is brand new and unridden.
Designed to withstand, designed to disrupt.
