Engineered to perform
A guide to the Xeno design
The fully modular Xeno hub is machined from aircraft-grade aluminium and features a double-axle, disc-side drive, a unique bearing layout, and more in our patent-pending Infinity Drive design.
​
By rethinking the traditional hub design, Xeno unlocks a range of surprising performance benefits.

Explore how these benefits come to life.
Watch the video below to see the key features explained.
DOUBLE-AXLE
By extending the freehub body all the way through the outer hub shell, it becomes what we call the drive shaft - a secondary axle with a much larger diameter than the primary axle.
Together, these two axles create an exceptionally stiff hub structure - 1000% stiffer than competitors' axles.
Some riders notice this immediately. On conventional hubs, flex in the axle can be felt when landing jumps or under heavy load, where the wheel seems to wobble or move slightly from beneath you. The Xeno hub’s double-axle design eliminates this sensation by keeping the hub rigid and the wheel precisely aligned.
This stiffness also delivers additional advantages behind the scenes. Reduced axle flex helps lower internal drag and significantly increases the lifespan of the hub’s bearings and ratchet mechanism.
DISC-SIDE DRIVE
On the Xeno hub, the ratchet is not squeezed inside the hub shell. Instead, it sits on the opposite side of the hub, inside the brake disc, and is driven by the drive shaft.
This layout allows the ratchet to be significantly larger and lets it take advantage of the strength of the brake disc. The increased size spreads the loads more effectively and allows for more - and larger - pawls.
The result is a ratchet that is stronger, more reliable, and capable of faster engagement. When it eventually wears, it is also quick and easy to replace.
UNIQUE BEARING LAYOUT
The Xeno hub uses a unique double-axle bearing layout with two independent bearing pairs.
The freewheeling pair sits on the drive shaft, while the pedalling pair sit inside the drive shaft.
​
Each pair consists of what is known as a locating bearing and a floating bearing, positioned as far apart as possible to minimise bending of the axle.
​Unlike conventional hubs - where the system often requires 4 or 5 bearings to rotate together - the Xeno layout ensures that only two bearings are rotating at any one time.
​The locating-floating bearing system also prevents unwanted bearing load. In many hubs, tightening the wheel onto the bike compresses the bearings, increasing friction. With Xeno hubs, tightening the system does not add unwanted load to the bearings.​ These changes ensure lower internal drag and longer bearing life.
MODULAR DESIGN
Built from 8 main precision-machined aluminium components, every part of the KOM hub is designed to be replaced, upgraded, or customised - without changing the rest.
Switching cassette standards? Just swap the cassette holder. No new hub required. This keeps costs down, reduces waste, and means your hub evolves with you rather than being replaced.
​
The same logic applies to aesthetics. Choose your hub shell colour, pick your endcap colour, and build a wheel that's unmistakably yours.
