Ass Savers Win Wing fender.

$27.00

Ass Savers have been at the light weight quick-install fender game for years and years, and they are always upping the game with their designs. For their latest release they’ve massively improved function by many orders of magnitude with the new Win Wing fender (or mudguard if that is what you want to call it.)

We first put a prototype Win Wing to work at Unbound 200 this year and when the rain hit the course hard we were genuinely the only riders with clean, dry derrières. Over the 200 miles of gravel the system performed perfectly, and that is about as trying a set of test conditions get for a fender!

Win Wings will fit pretty much any bike by attaching to the seat stays, not the seatpost or seat. The design mounts in a minute or less, and adjustment is quite easy via the three position notches on the fender itself.

The Rodeo Win Wing is offered in a vibrant red color with our signature topo lines and is available exclusively from us.

“…a satisfying experience, easy to install, unnoticeable, and always safe from mud”

The Win Wing Gravel fits practically any gravel bike, protecting the rider in even the worst conditions. No matter the terrain, on-road or off, the Win Wing won’t rattle or jam, and with only 72g, you won’t even notice it’s there.

Based on the principal of Tangential Coverage, the Wing Wing catches the spray by shielding the upper rear quarter of the wheel, protecting your critical areas (thighs, butt and back) and drastically increasing your comfort. And when comfort can be had without a weight penalty, that’s what we like to call a “win-wing situation”.

Technical data
Measures: 375 x 85 mm
Weight: 72 g
Material: Blade – 0.9 mm PP (Polypropylene),Wishbone holder – glassfiber reinforced PA (Polyamid 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 5-10 mm tire clearance for maximum coverage.

The right angle
Just as important as a tight fit is the angle of the blade. There are three different settings to compensate for the angle of your seat stays. Choose the one that allow a horizontal or a 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.

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 of large chunks of nature get stuck to your wheel.

Anti-Theft
If you like to keep it attached to your bike permanently, the Win-Wing can be secured to your bike with a standard zip tie, through a designated slot, making it easier to resist for people with sticky fingers.

Reliable
Thanks to it’s sophisticated simplicity and careful choice of materials, the Win-Wing is virtually indestructible. With only four components (competitors use as much as 40 components) it’s not that much that can go wrong. 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/see the instruction video to ensure the best performance.

Sustainability
The black blade is made from 80% 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.
