Ass Savers Win Wing Rear Mudguard

The highly anticipated Win Wing MTB has finally arrived! We've brought our successful concept of tangential coverage to the world of trails and dirt. To accommodate wider tires and diverse frame geometries, we've redesigned the Win Wing from the ground up.

eaturing a length-adjustable and reinforced wishbone, specifically adapted for knobby tire profiles, and a structurally enhanced, larger blade, the new design ensures optimal protection on virtually any mountainbike. Whether tackling rugged trails or muddy paths, the Win Wing MTB is built for ultimate performance and coverage.

Specifications

• Full backside rider protection from the knee and up
• Ultralight - 114 grams
• Fits all MTB types from 26" to 29"
• Attaches in seconds without tools
• Suitable for tire widths up to 3.0" (76 mm)
• Weight: 114g

Material

Blade – 0.9 mm PP (Polypropylene), Wishbone holder – glassfiber reinforced PA (Polyamide or Nylon), and Strap – TPU (Thermoplastic Polyurethane).

Tangential Coverage

The key to understanding how the Win Wing works lies in physics: water and mud leave the wheel in a straight line from the tangential point of release. By shielding only the upper rear quarter of the wheel, the Win Wing eliminates spray from reaching the critical areas of the rider with a minimum of material.

Mount Right, Mount Tight

For the Tangential Coverage to work properly, the mudguard needs to be installed very close to the wheel. Aim for approximately 10 mm tire clearance for maximum coverage. The optimal horizontal position is to have the wishbone pin positioned at the zenith of the tire. Adjust the length of the wishbone to achieve the optimal position for your frame geometry.

The Right Angle

Just as important as a tight fit is the angle of the blade. There are four different settings to compensate for the angle of your seat stays. Choose the one that allows a horizontal or tail-up position. Avoid a tail-down angle, as this will reduce the efficiency of the fender.

Strap It Hard

The straps are made from ultra-tough TPU and should be pulled as tight as you can comfortably do by hand. If you experience that the mudguard is not stable, try to use the next hole in the strap.

Protect What You Love

We have made the Win Wing as kind to your bike as possible with soft rubber feet that gently hug your frame. However, anything that is strapped to your bike for a longer period of time will leave marks. If you are very keen on maintaining that new bike look, please remember to install the frame protection stickers where your Win Wing is attached.

Anti-Jam

As sturdy as it is, the design of the Win Wing allows it to flex in case of an accident, and it's constructed to not jam in case large chunks of nature get stuck to your wheel.

Reliable

Thanks to its sophisticated simplicity and careful choice of materials, the Win Wing is virtually indestructible. The glassfiber reinforced wishbone holder is both flexible and tough, and the rubber straps are virtually indestructible.

Pre-Folding

The secret to transforming a flat piece of plastic into a functioning mudguard lies in the pre-folding prior to use. All the scoring lines have been carefully engineered to achieve locking mechanisms, self-centering abilities, spring loading, and material endurance. Please take the time to properly read the instructions or watch the instruction video to ensure the best performance.

Sustainability

The black blade is made from 50% recycled PP and the Win Wing has been designed for efficient shipping and easy recycling. Each component can be purchased separately, making repairing and upgrading convenient. The Win Wing is 100% Made in Sweden in ISO 14001 certified factories.
