Suspension forks for 27.5" bikes

Suspension forks for 27.5" bikes are a great choice for mountain bikers looking to strike a balance between performance and weight. They offer more travel than 26" forks, but are still lighter than 29" forks. This makes them ideal for a variety of riding styles, from cross-country to enduro.

Main advantages of 27.5" suspension forks:

Versatility: 27.5" suspension forks are suitable for different riding styles and different types of terrain. They are ideal for cross-country, trail, enduro and even some downhill.
Performance: 27.5" suspension forks offer better performance than 26" forks due to their greater travel and stability. They also overcome obstacles more easily, making them a good choice for technical terrain.
Weight: 27.5" suspension forks are lighter than 29" forks, making them more efficient when climbing and accelerating.

If you're looking for a suspension fork that offers the best balance of power, weight, and versatility, then a 27.5" suspension fork is the right choice. When choosing a suitable suspension fork, be sure to consider its features such as: travel, neck diameter and headset compatibility, suspension type, damping adjustability, and fork lockout.

What types of 27.5" forks are commonly available?

27.5-inch forks are commonly available in two designs:

Air forks: Lighter, more responsive, and allow for precise adjustment of damping using air pressure (based on rider weight). Requires a special pump.
Spring forks: Durable and more affordable. Stiffness is usually changed by replacing the steel spring, which is less flexible than air. Suitable for recreational riding.

How to choose the right fork travel for a 27.5" bike?

The stroke (indicated in mm) is chosen according to the riding style and type of bicycle:

100 – 120 mm: For XC (Cross-Country) and marathons – fast and efficient riding.
130 – 150 mm: Trail/All-Mountain – versatile riding in varied terrain.
160 mm and above: Enduro/Downhill – maximum stability and control in challenging terrain.

When selecting a fork, always follow the frame manufacturer's recommendations! Increasing the travel can negatively affect the geometry and strength of the frame.

What is a “fork post” and what kind do I need?

The 27.5" fork stem is the tube that passes through the frame's head tube and holds the handlebars.

Tapered: The most common modern standard. The stem widens at the crown (from 1 1/8" to 1 1/2"). Offers greater stiffness and better handling.
Straight: The classic standard with a diameter of 1 1/8". It is more often used on older or cheaper frames.
Compatibility: Must match the head tube size of your frame.

What wheel (axle) mounting system is standard for 27.5" forks?

15 mm thru-axle (Boost/Non-Boost): The modern standard for strength and precise steering.
- Boost: 110 mm width (wider hub spacing for a stiffer wheel).
- Non-Boost: width 100 mm.
9 mm QR (Quick Release): An older and less rigid variant, more for recreational and cheaper MTBs.

It is important to have a wheel hub compatible with the fork axle system.
