Fixed axle or bearing axle diabolo
The one decision to make before buying a diabolo. What a fixed axle and a bearing axle each do, which tricks need which, who should start on which, and which Sundia model fits.
Updated
Decide the axle before the model. A fixed axle grips the string, so you feel and steer the diabolo directly; it is the home of the classic tricks and the only way into playing two or three diabolos. A bearing axle spins much longer on a single pull, in one direction, and is what vertical play, long combos and grinds are built on. Neither is better.
Fixed axle
The string wraps around a steel axle that does not turn independently of the cups. Every pull accelerates the diabolo, and every touch of the string transmits information back to your hands.
- What it is for: the whole classic repertoire, including the string climb and suicides, wraps, slacks and knots, and multi-diabolo play such as the two diabolo shuffle, which is impossible on a bearing because two diabolos on one string need friction to be steered.
- What it costs: 22 € for an Echo 2.0, 40 € for the EVO G2. Lighter (215 to 240 g), nothing to maintain.
- What it demands: the spin has to be kept up. A beginner spends the first weeks learning to accelerate without tilting.
Bearing axle
The axle holds one or more one-way ball bearings, so the diabolo keeps spinning in one direction while the string slides freely in the other.
- What it is for: vertical play (“vertax”), long combos, body moves, stick grinds, and anything where you want the spin to outlast the trick. Children often prefer it: the diabolo keeps going, so the reward comes sooner.
- What it costs: 29 € for the Echo 2.0 Bearing, 55 € for the Falcon, 66 € for the Magforce. Heavier (240 to 265 g), and the nuts want re-tightening now and then.
- What it forbids: tricks that need string friction. The elevator will not climb, and a second diabolo cannot be controlled.
Which bearing
| Axle | Bearings | Character | Model |
|---|---|---|---|
| 1-B | 1 | Entry level, quiet | Micro |
| 3-B | 3 | The standard; best balance of stability and durability | Echo 2.0 Bearing, Falcon, Fly |
| 5-B | 5 | Fastest acceleration for one-minute routines; smaller parts, more fragile | EVO G3 5-B |
| Magnetic 3-B | 3 plus magnets | Smoother than a 3-B, sturdier than a 5-B, 2 mm larger | Magforce, Magforce NX |
Bearing models always come with the harder or semi-flexible cups: soft cups pass the shock of a drop straight into the bearings and bend the bolt over time, so Sundia does not combine them. Sundia’s bearings need only an occasional drop of Long Spin Oil.
Who should buy which
- A first diabolo, any age from about 8: fixed axle, EVO G2. See the best diabolo for beginners.
- A young child who gives up when the diabolo stops: bearing, Echo 2.0 Bearing. See diabolo for kids.
- A player after a year on fixed who wants vertax and combos: bearing, Magforce.
- A player who wants two diabolos: fixed, and a second EVO G2 with narrow hubs.
Bottom line
Fixed for control and the classic tricks, bearing for spin time and vertical play. Most players end up owning one of each; start with the fixed EVO G2 and add a Magforce when the tricks ask for it.
Questions
Is a bearing diabolo better than a fixed axle?
Neither is better; they are two kinds of play. A fixed axle gives direct control and is the only way into string climbs, suicides and two or three diabolos. A bearing spins much longer on one pull, in one direction, which is what vertical play, long combos and grinds are built on.
Which should a beginner buy?
A fixed axle, unless the beginner is a child who needs the diabolo to keep spinning while they learn. Fixed is cheaper, lighter, needs no maintenance and teaches the feel of the string.
Which tricks do not work on a bearing?
Anything that relies on the string gripping the axle: the string climb (elevator), most slack and wrap tricks, and two-diabolo play. Grinds, on the other hand, only work on a bearing.
What is the difference between 1-B, 3-B, 5-B and Magforce?
The number of bearings in the axle. Single bearing (1-B) is the entry level; triple bearing (3-B) is the standard we recommend; five bearing (5-B) accelerates faster for one-minute competition routines but is more fragile; Magforce is a 3-B with magnetic rings that reduce friction further.
