Rear mudguard Ass Savers Win Wing Gravel 2 Golden Groove

The Ass Savers Win Wing Gravel 2 rear mudguard helps protect against water and mud thrown up by the wheel. It covers the upper rear section of the wheel and attaches to the bicycle frame.

Tangential coverage

Water and mud leave the wheel at the tangential point and travel in a straight line. By covering only the upper rear quarter of the wheel, the Win Wing deflects spray away from the rider’s critical areas while using a minimal amount of material.

Fitting and positioning

For tangential coverage to work properly, the mudguard needs to be installed very close to the wheel. For maximum coverage, leave 5–10 mm of clearance between the tyre and the mudguard.

The blade angle is also important. Three settings are available to accommodate the angle of the seat stays. Choose a horizontal or tail-up position. A tail-down angle reduces the mudguard’s efficiency.

The straps are made from tough TPU. Pull them as tight as is comfortable by hand. If the mudguard is not stable, try using the next hole in the strap.

Frame protection and durability

Soft rubber feet gently rest against the frame. However, anything strapped to a bike for a long time can leave marks. To help maintain the bike’s new appearance, apply protective tape where the Win Wing attaches.

The mudguard is sturdy but can flex in an accident. Its design also helps prevent it from jamming if large pieces of debris get caught in the wheel.

The Win Wing can be secured to the bike with a standard zip tie through a designated slot. This makes it harder for other people to remove.

Thanks to its simple design and carefully selected materials, the Win Wing is highly durable. It has only four components, while competing products can have as many as 40. The glass-fibre-reinforced holder is flexible and tough, and the rubber straps are highly durable.

Preparing for use and sustainability

The flat plastic piece must be pre-folded before use to turn it into a functioning mudguard. The scoring lines are engineered to provide locking mechanisms, self-centering, spring loading and material endurance. For the best performance, read the instructions carefully or watch the instruction video.

The black blade is made from 80% recycled PP. The Win Wing is designed for efficient shipping and easy recycling. Each component can be purchased separately, making repairs and upgrades convenient. The Win Wing is 100% made in Sweden in ISO 14001-certified factories.
