The Threeworlds Fusion Ultra Dragon Staff Hubs are pressure-fit dragon staff hubs designed for the Fusion system, combining a secure connection with the ability to quickly install or remove your hubs for travel, storage, and different staff configurations. Each hub accepts either 3 or 4 spokes, allowing you to customize the feel and configuration of your dragon staff.
Unlike permanently mounted hubs, the Fusion Ultra uses an expandable pressure-fit connector that inserts directly into compatible 3/4 inch ID (19 mm ID) staff tubing. Tightening the connector compresses the internal rubber bushes, causing them to expand against the inside of the tubing and securely hold the hub in place.
Pressure-Fit Fusion Connection
Each Ultra Hub uses a short Fusion Cam Bolt with 2 Fusion Nylon Washers and 2 Fusion Rubber Bushes alternating beneath the cam bolt. A D90 O-Ring sits at the base of the connector.
As the connector is tightened, the rubber bushes compress and expand outward against the inside wall of the staff tubing. This friction is what helps hold the hub securely in place while still allowing it to be removed when needed.
For a closer look at assembly, adjustment, and maintenance, read our Guide to Fusion Pressure-Fit Connectors.
3 or 4 Spoke Configurations
Fusion Ultra Hubs can be configured with either 3 or 4 dragon staff spokes per hub. This gives you the flexibility to adjust the weight, visual profile, and overall feel of your dragon staff without changing hubs.
If you’re deciding how many spokes to use, our 3, 4, or 5 Spoke Dragon Staff Guide breaks down the practical differences between common configurations.
Easy Spoke Installation
Spokes are secured to the hub using 3 mm hex hardware, making installation and removal straightforward with a 3 mm Allen Key. This makes it easy to remove your spokes for transportation or swap between compatible fire, LED, and daytime setups.
For installation instructions, check out our How to Install Spokes into Dragon Staff Hubs guide.
Ultra vs. V3 Dragon Staff Hubs
The Fusion Ultra Hub is designed around the removable Fusion pressure-fit connector and fits compatible 3/4 inch ID (19 mm ID) staff tubing. If you’re looking for a hub designed to clamp around a contact staff rather than insert into the end of the tubing, check out the Threeworlds Fusion V3 Dragon Hub.
Not sure which system is right for your setup? Our V3 vs. Ultra Dragon Staff Hubs guide covers the differences between the two designs.
Built for Collapsible Dragon Staffs
The removable hub and spoke system makes the Fusion Ultra particularly useful for travel and compact storage. Instead of transporting a fully assembled dragon staff everywhere you go, the hubs and spokes can be removed and packed separately from the staff body.
Just remember that pressure-fit connectors depend on friction. Keep the rubber bushes and the inside of your staff tubing clean, dry, and free of dust or oily residue so the connector can tighten properly.
