With its 35mm stanchions, boost spacing, and advanced damping system, it’s a reliable option for both competitive cyclists and those looking for enhanced trail comfort.

Key Features of the Zeron 35 Boost

1. Boost Hub Spacing

The Zeron 35 Boost suspension fork uses the Boost hub standard with 110mm spacing in the front wheel. This design increases wheel stiffness, improving handling, cornering stability, and overall performance, especially on rougher trails. The wider hub spacing creates a stronger connection between the hub and fork, enhancing the power transfer from the rider to the bike.

2. 35mm Stanchions

One of the standout features of the Zeron 35 Boost is its 35mm stanchions. This larger diameter improves the fork’s overall rigidity, reduces flex, and enhances handling precision. Riders will notice increased stability, particularly on aggressive descents and technical terrain. The 35mm stanchions are a key factor in reducing weight while maintaining strength, offering a balanced performance profile for a wide range of riders.

3. Air Spring System

The Zeron 35 Boost utilizes an air spring system, allowing for adjustability based on rider weight and riding style. The air spring is lighter than a coil spring and provides more flexibility, which results in a smoother ride. Riders can fine-tune the fork’s performance by adjusting the air pressure to match their preferences, providing a more personalized setup for different trail conditions.

4. Damping Technology

Equipped with SR Suntour’s proprietary damping technology, the Zeron 35 Boost fork offers excellent control over rough terrain. The damping system is designed to absorb shocks and bumps efficiently while maintaining sensitivity for small impacts. This results in enhanced comfort and traction during both climbs and descents, especially on more technical routes. The fork’s damper provides controlled compression and rebound, preventing excessive dive during braking or acceleration.

5. Tool-Free Adjustments

Adjusting the Zeron 35 Boost is simple and tool-free, thanks to intuitive knobs for adjusting both compression and rebound. This feature makes it easier for riders to tweak the fork’s performance on-the-fly, allowing for quick responses to varying trail conditions. It’s especially useful for riders who frequently adjust their suspension settings or for those new to suspension tuning.

6. Lockout Feature

The lockout function of the Zeron 35 Boost is a convenient feature for riders who need to minimize suspension movement on smooth or paved surfaces. This feature helps conserve energy during long climbs or flat sections, allowing for more efficient pedaling. When locked out, the fork remains stiff, providing a more direct power transfer. The lockout is easily accessible, making it easy to switch between suspension and rigid modes without interrupting your ride.

7. Durable Construction

The Zeron 35 Boost is constructed with lightweight materials, including an aluminum crown and magnesium lowers, which reduce overall weight without compromising durability. This makes it a suitable choice for cyclists who need a reliable and long-lasting fork that can withstand frequent use on a variety of trails. The fork’s tough construction is designed to handle both aggressive riding and everyday trail use.
