Frey Dopamine now is available for pre-order, which has won the attention of many cycling enthusiasts.

For the most interesting geometric design lies in the high pivot design, which will raise the main pivot of the bike above the chainring and rear axle, and utilizing an idler pulley, the chain growth and pedal kickback are effectively reduced. 

 

 

We received a lot of questions about this design, such as "Why does the chain come up from the main chain ring to that small gear?" "What is the advantage of chain routing?"

Today, let's talk about Frey Dopamine's high pivot design!

 

So What is a high pivot?

"high-pivot" refers to a suspension design where the rear axle is positioned higher than the main pivot of the bike's suspension system. 

This design allows the rear wheel to move in a path that is initially rearward and upward when encountering obstacles, which is believed to provide better traction, improved absorption of impacts, and a smoother ride. 

 

Why choose a high-pivot design?

We chose to incorporate a high-pivot design in our new bike model to provide riders with better suspension performance, increased traction, and enhanced suspension travel during downhill rides. This allows riders to experience a more passionate and controlled riding experience. 

As our product development department puts it: 

"Compared to traditional suspension designs, a high pivot point has inherent advantages on downhill sections. The initial rear wheel path moves upward and backward, which, from a kinematic perspective, closely aligns with the relative motion of obstacles. This results in a smoother, ground-hugging suspension effect. It allows for a full release of the thrill of conquering uphill challenges without any reservations."

 

What is the advantage of high pivot?

The high pivot design offers several inherent advantages in cycling, which is often favored for downhill and aggressive trail riding, as it can help the bike maintain better contact with the ground and handle rough terrain more effectively.

Firstly, it allows the rear wheel path to closely follow the relative motion of obstacles, resulting in a smoother and ground-hugging suspension effect. This means our bikes can better absorb bumps and impacts, providing a more comfortable riding experience for cyclists.

Secondly, the high pivot design contributes to improved traction. By positioning the rear wheel higher and further back, we ensure better ground contact and increased surface area, enhancing grip. This is especially crucial for handling steep descents, rough terrains, and sharp turns, enabling riders to have better control over the bike.

Lastly, the high pivot design provides greater suspension travel. This is beneficial for handling large impacts and high-speed descents, making the ride smoother and enhancing overall stability and control.

 

You may have the following questions about this design:

Q: What are the differences between a high-pivot bike and a regular bike?

A: 

One of the main differences is in the rear suspension performance. A high-pivot bike's rear axle is positioned higher than a regular bike, allowing the rear wheel to move more independently from the rest of the frame. 

In addition, high-pivot bikes utilize idler pulleys or other mechanisms to mitigate chain growth and pedal kickback. This allows riders to maintain better momentum and power transfer while encountering obstacles or rough terrain.

 

Q:  Is this would make the chain longer and more expensive when it comes time to replace it?

A: 

When it's time to replace the chain, you may need a slightly longer chain to accommodate the larger suspension movement. This may increase the cost of chain replacement compared to a regular bike.

However, it's important to note that the difference in chain length is typically minimal and may not significantly impact the overall cost. 

The cost of chain replacement is influenced by various factors such as the brand, quality, and specific model of the chain. While a slightly longer chain may be required for a high-pivot bike, the price difference may not be significant compared to a regular bike.

 

Q: Does this upper sprocket isn't a source of problems during rough rides?

A:

While the risk of the upper sprocket hitting obstacles exists during rough rides, our product team considers careful frame and component design to ensure adequate clearance between the sprocket and the terrain when designing Dopamine.

If you are worrying about the risk, regular maintenance and inspection of the bike's drivetrain are recommended to identify any potential issues and ensure optimal performance.
