How do 360 handlebars work?
360 handlebars work by utilizing a special mechanism that allows them to spin freely in a full circle without tangling the brake cables.
On a standard bicycle, turning the handlebars more than 90 degrees would cause the brake and gear cables wrapped around the head tube to twist and eventually tighten, preventing further rotation and potentially damaging the cables or controls.
Bicycles equipped with "360 handlebars" are designed specifically to overcome this limitation, enabling the rider to spin the handlebars completely around multiple times.
The Role of the Detangler (Gyro/Rotor)
The key invention that makes 360-degree handlebar rotation possible is known by several names: the detangler, Gyro, or rotor.
According to the definition, the detangler, Gyro or rotor is an invention for the freestyle BMX bicycle, allowing the handlebars to turn a complete 360° rotation without the brake cables getting tangled up.
This system is typically used for the rear brake cable on freestyle BMX bikes, as front brakes are often not required for many tricks or riders prefer simpler setups.
How It Prevents Tangling
The detangler system works by essentially splitting the brake cable into two parts.
- An upper cable connects the brake lever on the handlebar to a rotating mechanism mounted on the bike's head tube.
- A lower cable connects this same rotating mechanism to the rear brake calipers on the frame.
The rotating mechanism (the detangler itself) consists of two plates that can rotate independently. This allows the upper cable section, which turns with the handlebars, to remain separate from the lower cable section, which is fixed to the frame. As the handlebars spin, the upper plate rotates relative to the lower plate, allowing the cable to pass through freely without twisting around the frame.
Why It's Important in BMX
The ability to spin the handlebars 360 degrees (or more) is crucial for many tricks performed in freestyle BMX, particularly:
- Barspins: Where the rider spins the handlebars one or more full rotations while in the air or on the ground.
- Tailwhips: Where the rider spins the frame of the bike around the handlebars.
Without a detangler system, performing these tricks would be impossible due to tangled brake cables.
System Overview
Here's a simple breakdown of the components involved in a 360-degree handlebar system:
| Item | Function |
|---|---|
| Handlebars | Rider's control point for steering and braking |
| Stem | Connects handlebars to the fork's steerer tube |
| Detangler (Gyro/Rotor) | Prevents brake cable tangling during rotation |
| Upper Brake Cable | Connects lever to detangler |
| Lower Brake Cable | Connects detangler to rear brake |
| Brake Lever | Activates the brake |
| Rear Brake Caliper | Stops the rear wheel |
This system allows riders the freedom to perform complex maneuvers that involve spinning the handlebars without interference from their brake cables.
