Spikey Spinner Hub - Accessory for Kaiko Spinners
Add concentrated safe ouch texture and high sensory input to your Kaiko Wheel Spinner and Kaiko Mega Cog.
The Spikey Spinner Hub is a pair of textured replacement centre pieces designed primarily for the Kaiko Wheel Spinner. They also fit the Kaiko Mega Cog, giving you a simple way to swap the standard smooth holding surfaces for a more intense, patterned tactile experience.
This listing is for the Spikey Spinner Hub pair only. The Wheel Spinner and Mega Cog are sold separately.
Focused texture with a harm-minimising rim
The raised patterned surface can provide focused fingertip pressure, rubbing and textured picking support. A protective rim sits around the Spikey texture, helping to keep contact within the small fingertip area and making the points more difficult to drag across broader areas of skin.
This is a harm-minimising design feature, not a guarantee against unsafe use. The hubs should be used as intended with fingertip contact and appropriate supervision (if applicable).

How to fit
Remove the existing smooth centre pieces from your compatible Kaiko spinner, then fit the Spikey Spinner Hubs in their place. Gently tighten until secure. Do not overtighten. Check regularly and retighten as needed during use.
Choosing the right fit
The Spikey Spinner Hub may suit people who actively seek strong, concentrated tactile input or who use picking, pressing or rubbing to regulate. It changes the centre contact surface of the spinner; it does not replace the spinner itself.
If you prefer smooth, low-intensity or subtle tactile feedback, the standard centre hubs may be the better fit. Start with what your system needs.
Who might find it helpful?
- People who seek strong or high sensory input through their fingertips
- Those who enjoy patterned metal texture
- People looking for a textured picking or pressing alternative
- Existing Wheel Spinner or Mega Cog users wanting a different centre feel
Helpful to know

Intended for fingertip contact only—do not scrape or drag the textured surface across the skin, use on broken or irritated skin, or place in the mouth. Stop use if irritation or discomfort occurs.

Temperature: Cool metal contact that warms with use.
Visual: Reflective oil slick colour and geometric texture.

Regulation style it suits

May not suit
