Product Information

PLACE. The next step to install the Win Wing is to attach the wishbone frame as close as possible to the rear tire. I found that loosely fitting the frame around the seat stays, adjusting its position about 5mm above the tread, then tightening the straps, was a foolproof method for a proper fit.

There’s also a slot on one-side to secure a zip-tie around it, not to keep it from falling off, but as a mini anti-theft feature for when you leave your bike unattended. Ass Savers Win Wing – Pricing, options & availability And who would have suspected that this road & gravel fender is perfect for protecting your dropper seatpost? This might be my favorite surprise in mounting the Win Wing. The more dropper posts expand beyond mountain bikes, the more riders will have to deal with maintaining droppers. As unlikely as it looks with its partial tyre coverage, this mudguard really does keep you clean from the knees up. I can’t say anything negative about this - it’s a piece of engineering I wish had been made a lot earlier. " The fender offers zero spray protection for anything below the top of your seattube. If you have it on a full-suspension bike (like this Canyon Lux Trail), the pivots are still exposed to spray and the swingarm will still fill up with mud… or in my case pine needles.A simple wishbone looped over your tire and strapped to the seatstays, the Win Wing fender stops mud and water right at the source. Ass Savers call it “tangential coverage”. The Win Wing stops spray at the tire, before it’s thrown towards your… ass. And I kinda love it, from road to gravel, even to protecting the dropper post seals on my XC bikes. Have a look at this BMC URS gravel bike and you can see the seatpost stayed totally clean (or at least as clean as it was before I mounted the fender). But everything below that still gets wet & muddy. The fender blade is made from 80% recycled polypropylene and has five holes that are used to connect it to the Wishbone. There are three in the front-center of the blade that are used to insert the peg at the top of the arc. Each of these options changes the angle of the wing and enables bikes of varying sizes to achieve the correct angle. Ass Savers recommends a horizontal to “tail-up” position to maximize performance. I mounted it using the middle hole, which tilted the blade slightly upward on a size large drop-bar 29er. There are two additional holes that match with the two outer Wishbone pegs—one on each “wing.” Once they’re all attached, it’s remarkably solid, given its scant 71 gram weight. With all of that said, it’s already hard to fault the original Ass Savers fender if you accept its limitations – literally just a simple ( and pretty well-designed) piece of folded plastic clipped to your saddle rails… and often copied. A regular Ass Saver doesn’t offer a ton of coverage either, but was/is a ‘better-than-nothing’ approach to at least keeping your butt from getting muddy and soaked on wet or sloppy rides.

if you plan on pedaling your gravel bike or ATB in wet and muddy conditions, the Win Wing is a no-brainer." It also moves the left-side slot away from the edge. So you can still secure the fender on your bike with a zip-tie, but with reduced chance of failure at a weak point there. In reality, the Win Wing fits a lot of bikes that simply won’t fit conventional fenders – no fender mounts required. But the biggest compatibility feature might just be that wide 19-60mm tire width clearance range. That covers almost every road, fixie, all-road, cyclocross, gravel, trekking, and cross-country bike out there. Two key selling points for the Win Wing fenders are that they fit a wide range of tires ( and bikes), and they are lightweight.

Plus, while many conventional fenders rattle over rough surfaces or any off-road, the Win Wing stays quiet and doesn’t shake loose no matter where you ride it. Even though it seems to sit perilously close to the rear tire, we haven’t had any issue with it jamming even on especially muddy rides. While the product actually consists of four parts—the Wishbone Mount, the Blade, and two straps—the straps are already attached to the mount upon delivery, so in practice it only feels like two parts upon first install. The Wishbone Mount is designed to be attached to the seat stays at an upward sweep in relation to the wheel. The ends of the Wishbone legs are slightly curved, to seat better against the seat stays and directly above each is a slot that the strap intuitively feeds through. It is then fastened tight by securing via one of the holes to the nub on the arm. The Blade then snaps onto the “U” of the Wishbone through mated holes punched in the Blade and small knobs on the Wishbone. 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. The simple attachment system also means that it’s super easy to swap between bikes and it is also compatible with a wide range of tyres. This has been a godsend as I have accumulated more and more test bikes to ride and fitting anything more complicated (or permanent) on each would be too much of an effort. The Win Wing takes about half a minute to take off from one bike and attach to another - and while swapping it around I’ve noticed it’s also not scratched my seat stays (I would still recommend attaching a piece of frame protection tape as a precaution). And if you’re worried about theft, Ass Savers has designed it with a little zip-tie hole so you can zip-tie it to your seat stays semi-permanently. The Win Wing Road fits practically any skinny tire bike, protecting the rider in even the worst conditions. Ideal for winter training or if you want to add some comfort to your puristic urban ride. The Win Wing won't rattle or jam, and with only 64g, you won't even notice it's there.
