CNC machined, stiff and extra light with innovative ratchet design!
This hub has been produced on high precision CNC machine, using quality aluminum alloy of 7075 series (T6 threated).
The hub is extra light and sturdy at the same time, incorporating new innovative Convex/Concave ratchet design. Due to its hollow design weight is further reduced, and its Convex/Concave shape provides a necessary ratchet strength, bigger engagement surface and better self positioning of the ratchets itself.

Top quality aluminium alloys and CNC machining
Bellani XC King has been produced out of the top quality aluminium alloy 7075 (T6). The hub cartridge has been extruded on 5 axis CNC machine, through couple of different stages of processing.
Innovative ratchet design and less weight
Bellani Convex/Concave Ratchet concept gives a light and stiff ratchet system. Due to its hollow design we have reduced the weight while its Convex/Concave shape gives a necessary strength and enabling better self positioning of the ratchet itself, at the same time. Additionally, utilizing a flat spring design, system demands only one spring to function correctly. The Classic DT Swiss Ratchet System requires two springs to function correctly.
Great rolling performance and bearing lifetime
Most (if not all) of the Super Light hubs on the market are reducing weight by installing small size bearings. Due to the clever hub design and CNC precise machining of the hub cartridge and light Convex/Concave ratchet, this hub has enough room to utilize the 6902 bearings, still keeping the weight in Super Light league. These bearings are the golden standard for all hubs looking to be durable and have a great rolling performance.
Complete engagement and greater system reliability
As per Convex/Concave Ratchet design, one side of the system is fixed, while other is self positioned against the first one. Using a flat (and thick) spring design and extruded groves inside the hollow ratchets, spring is fixed in place and pushing strong one side of the ratchet constantly, without been able to get jammed between the axle and the ratchet itself. All these facts will count for a faster and complete engagement, resulting in a greater reliability.
System durability
What Convex/Concave Ratchet System makes great is the fact that all teeth on each of the ratchet sides engage simultaneously, every time. In the case of pawl hubs, the engagement surface area is rather small. This inovative Convex/Concave design provides a bigger face surfaces that will engage with each other, resulting in a much smaller point load. The result is a reliabile and durable hub.
Easy maintenance
This hub is maintained as any other DT Swiss hub using Classic DT Swiss Ratchet design, and thus is versatile with any of the DT Swiss Ratchet design as well. All spare parts like bearings and Convex/Concave ratchet system will be available to buy separately, here, at Bellani Composite store.
