Fixed forks, also called “rigid”, are designed for unsuspended bicycles. They are usually made of strong and light materials such as steel, aluminium or carbon fibre. Rigid forks are designed to provide a rigid and direct connection between the front wheel and the frame, thus providing stability and precision. They are commonly used on road, city and some mountain bikes. Stiff forks provide better power transmission compared to suspension forks. They are also generally lighter, making the bike more agile and efficient when choosing a fixed fork, don't forget to consider the following parameters:
- Material: Rigid forks can be made from a variety of materials including steel, aluminium or carbon fibre. Each material offers different levels of strength, weight, and vibration dampening properties.
- Axle compatibility: Forks come with a variety of axle compatibility options, such as quick release (QR) or solid axle. The axle type should match the hub of the front wheel to guarantee proper compatibility.
- Fork neck: The fork neck connects to the bicycle frame. It comes in a variety of lengths and diameters, so it's important to choose a fork compatible with your frame's head assembly and head tube to get the fork installed correctly.
- Brake compatibility: Rigid forks can be designed to accommodate different types of brakes, including rim brakes or disc brakes. It is important to pick a fork that is compatible with the type of braking system used on the bike.
- Tire clearance: Fixed forks have specific tire clearance limits that determine the maximum tire width that can be used. It is very important to choose a fork that will accommodate the correct tire size for your intended use.
Are there advantages to a rigid fork over a suspension fork?
Using a rigid fork has several advantages over a suspension fork:
- Efficiency: The rigid fork provides a direct and efficient transfer of power from the rider's pedals to the front wheel. There is no energy loss due to suspension movement, resulting in a more efficient ride, especially on smooth surfaces and roads.
- Light weight: Rigid forks are generally lighter than suspension forks because they do not require additional components such as air suspension systems or springs. This weight reduction can improve the bike's overall handling and response.
- Maintenance: Fixed forks are relatively easy to maintain compared to suspension forks. They do not require regular service or adjustment, as they have no moving parts or seals to wear or require maintenance.
- Precise control: Rigid forks offer more precise and predictable control, especially when cornering and changing direction quickly. The absence of suspension movement allows for better control and response, making them popular with riders who prefer precise steering.
- Cost: Rigid forks are usually more affordable than suspension forks. This makes them an affordable option for riders who don't require or prefer higher comfort and suspension features.
- Durability: Rigid forks are generally more durable and less susceptible to mechanical failure or damage compared to suspension forks. They are less susceptible to wear and better withstand harsh driving conditions.
Is it possible to use a fixed fork on a mountain bike, or are they only suitable for road bikes?
Yes, you can use a fixed fork on a mountain bike. Although suspension forks are the standard for off-road mountain biking, there is now a growing interest in using rigid forks for certain types of mountain biking. Rigid forks offer advantages such as higher efficiency, precise control and lower weight compared to suspension forks. Rigid forks are especially suitable for riding on smoother roads, gravel paths or even for bikepacking and hiking purposes.
