NonPlus Ultra Hub Set becomes PRIMARO ULTRA Hub Set
With the ULTRA Series, we go one step further. Born from the pursuit of ultimate refinement, it is more than just a product – it is our vision of uncompromising performance, brought to life.
At its peak: the ULTRA hub. Lighter than anything we’ve ever built. Tested under the harshest conditions. A masterpiece of precision, efficiency, and raw speed – for those who don’t just ride at the front, but lead the way.
With a total weight under 190 grams (sub 190), the ULTRA hub redefines the standards of lightweight design. And while it’s considered the world’s lightest Centerlock hub set, it’s engineered without compromise – made to excel on gravel, road, and race courses alike.
Every single component has been refined down to the hundredth of a gram – not just to save weight, but to deliver measurable efficiency: a high-speed seal with glide coating, a low-friction coated freehub body, and an optimized ratchet ring reduce drag to an absolute minimum.
Inside, coated Enduro ceramic bearings ensure a silky-smooth ride and lasting performance – even under extreme loads.
The spoke interface has also evolved: with an optimized spoke angle and a wider drive-side flange, the rear hub delivers enhanced lateral stiffness and increased wheel longevity.
The new ULTRA Series – engineered beyond all known limits. By NonPlus Components.
