Gradient WideR 29in Boost Wheelset

P.R.A. Hubs, designed by FSA (Full Speed Ahead), feature a quick engagement system that allows for rapid response when you start pedaling. This is particularly beneficial for climbing steep hills and navigating technical trails, as it provides immediate power transfer and enhances your overall riding efficiency.

An asymmetrical spoke design arranges the spokes unevenly around the hub, which increases the wheel's durability and stiffness. This design is ideal for aggressive riding styles, such as enduro and trail biking, as it helps the wheels withstand the stresses of rough terrain and improves handling.

Tubeless tires eliminate the need for inner tubes, allowing the tire to seal directly to the rim. This setup enables you to run lower air pressure, which enhances traction and reduces the risk of pinch flats. Tubeless systems are especially popular in mountain biking for their ability to provide a smoother ride over rough surfaces.

Boost spacing refers to a wider hub and axle standard that allows for increased stability and the use of wider tires. This design improves the bike's handling and strength, making it particularly advantageous for mountain biking, where stability and control are crucial on challenging trails.

The internal diameter (29mm) is the width where the tire sits, while the external diameter (35mm) is the overall width of the rim. These measurements are critical as they determine the compatible tire sizes and influence the wheel's performance in terms of traction and stability. Choosing the right diameters ensures optimal performance for your riding style.

Not all tire sizes are compatible, even if you know the internal and external diameters. It's essential to refer to the manufacturer's specifications for recommended tire sizes that fit your specific rim measurements. This ensures that you achieve the best performance and safety while riding.
