The ass saver win wing is great. Works well on the gravel bike and is nice and simple to put on and off my road bike when riding to hill climbs and warming up.
It would be nice to have one that works on a MTB. Ass saver don't do one (yet?) but is there anything similar out there. Got a mudhugger on my hardtail that lives on there permanently because I don't want to be getting through zip ties. Be nice to have something lighter and similar to the win wing.
Not that I'm aware of. Ask ass savers?
70g so say 100g for a mtb one, vs. 300g for the large mudhugger rear.
One just arrived yesterday, the 50-60mm version.
I offered it up on wife's HT either 2.35 or 2.25 Barzos - can't remember and she's out on it now. There was maybe just enough clearance, no idea how it handles mud, stones, bouncing around, so I didn't leave on for her ride this morning (plus I don't want it broken before the all-day ride I bought it for tomorrow! I read a review saying it worked fine on mtbs, I'll see if I can find it.

He's got it quite high up, plenty of room for crap on the tyres to bounce through, it's only the sidewalls close to the wishbone supports.
As you can see in the photos above, there’s 6-7mm of space when mounted with 2.35/2.4” tires. I think it would be better with tires smaller than 2.25” wide, but it worked fine with these. I never had any issues with tire rub or chunks of gravel causing any harm to the Wishbone or fender blade, which was certainly one of my concerns. We’ve all had a chunk of gravel get wedged in the tire’s side knobs, only to knock into the chainstays upon rotation. However, with the rotational direction and the fact that the straps act as flexible suspension for the Wishbone, I don’t see it being an issue, and I haven’t had any problems with it after several very rough dirt road and gravel rides.
Been using one on my XC (FS) and on my rigid 29er bike since last year...both have 2.25" tyres and it works fine (dead easy to swap it over too)
I don’t want to be getting through zip ties
I just use re-usable zipties
I have the gravel one and use it on my hardtail with 2.6 tyres
I just ‘massaged’ the support bracket with hot water from the kettle to widen the bridge area to give the clearance. Works fine so far
Good to know, thanks for that!
I just use re-usable zipties
New ones come with rubber buckle-hole voile type straps.
Oh it's for gravel bikes - don't care.
I found that the mudhugger I have and was planning to use on my hardtail as well does not fit because the brake hose guides on the seatstay are in the way. So I may be interested in something like this.
Oh it’s for gravel bikes – don’t care.
And it works on some mtbs? the whole point of the thread? Or did you delete something you posted before because you realised it was irrelevant?
Maybe I'll try some gentle heating. Looks like the mudhugger can go on permanently right now anyway.
I've ran one on hardtail with 2.25" tyres. Yes it can clatter if it's really rough at speed, but 90% of the time it just worked well.
Id put one on my xc-fs if it fitted dropped seatstays.

Aren't all zip ties reusable?
I may give one a go on MTB, though I usually just accept a Mudhugger fixed on for six months of the year.
That weirdy beardy gravel bloke tested the Mk2 strap-on version
I have one of the gravel ones, fits great on both my mtbs. (I have to have it at a slightly odd looking angle on the full suss but it ended up working really well, probably better than if I could have put it exactly where I wanted it. Fantastic product, if it fits, I love it. Looks daft but every rear mudguard ever made looks daft. Whoever realised "we can just make it super light instead of making it heavy and stiff then trying to stop 300g of mudguiard from moving" is a genius. It doesn't quite have the coverage of a mudhugger but on both mine it has all of the really important arse coverage, so it's like 90% as effective maybe. And it's so quick to fit/remove.
But the challenge for a truly mtb compatible one is pretty obvious, we have a wild range of seatstay heights and some bikes with none at all so trying to offer a one-size-fits-all with this design is always going to be really difficult, and more so with this sort of design. In the meantime, I reckon most bikes with reasonably symetrical, not-too-fat, reasonably high chainstays can take one and probably pretty much all hardtails?

10% offer code too.
I use mine on my hardtail MTB. It's not quite as effective as on the gravel bike due to the seatstay angle but still keeps the ass area happy
Has a more sensible angle on my XC HT then on my Revolt due to seat stay geometry.Takes seconds to swap. I taped the contact points on both to minimise faff
That said I've just dusted off an old set of full SKS guards and fitted them to the Revolt to see if reduces spray to my feet after some soggy recent commutes. It is now even more fugly... Not yet tried them with the gravel wheels..
Thread resurrection...just before the rains return.
For those like me who love the win wing, I have one on my hardtail and it does a great job with minimal rubbing in the rough stuff, but have a FS and the wing doesn't offer the coverage, well, don't know when it happened, but they've released a MTB version! (apologies if this has been covered elsewhere)

Looks like it'll work on dropped seatstay bikes and has a decent amount of adjustment.
Oh excellent, I'm still using my gravel one on the mtbs but that looks like it'll work on a lot more bikes, good stuff
Already bought one! Obviously haven’t needed it yet so can’t comment on how good it is, but the fit looks as good as the cross bike one so high hopes.
I have been using the win wing on a MTB for a year on a 2.25 tyre it’s a bit of a game changer, so good I left it on for the whole winter and didn’t bother with the more serious mud guard I usually put on for winter - unfortunately it has a design fault as sold (not solved on MTB version ) over time and vibration the little mushrooms that poke through the plastic blade to make the angle adjustable wear the plastic and it falls apart. Can’t be fixed with glue due to the plastics used. The solution is to set the angle you need and screw through the blade into bridge with self tapers. It’s done a few months repaired like this so far and been fine

Thats interesting. I've 2 of the standard win wings and that's not happened to either of mine despite mild neglect.
They are great though, surprisingly so. I keep mine on all year round as it's light, doesn't get in the way and is aesthetically more pleasing than a crud race guard (remind me a bit of the original crud guard). plus there is no way I'll ride without some sort of mudguard.

It was in Fresh Goods Friday, I think last week, but oddly they didn't mention that it was a new product and the angles had been adjusted to work with mountain bike seat-stays. Brilliant things, I have one on my gravel bike, and I'd buy the mountain bike one in a shot if it weren't - touch wood - so ridiculously dry out there.
I guess it's worth pointing out that if it works as per the gravel version, it'll keep the crap off your seat and above, but won't protect legs or areas of the frame much below the top-tube / seat-tube junction. Way more convenient than a Mudhugger for occasional use and far less aesthetically heinous.
Neither of mine have worn as above or otherwise failed.
Are these significantly better than the original saddle mounted ass-savers? I've got them on most of my off-road bikes as like the little fork crown guards they weigh nothing and do 90% of the job 100% of the time.

IMHO, yes as they catch almost all the crap at the source, (i.e. the tyre) rather than just that which is fired into that narrow saddle width trajectory.
Must admit I've been impressed with the gravel WinWing I've had on this last year. I tried it on my hardtail - it just cleared, but the one ride I used it on was very windy and the combination of the wind and much more abusive riding meant the flat plastic bit kept getting blown/shocked into contact with the tyre and then dragged under the arch, obviously suboptimal! Possibly "perfect storm" conditions, but not as foolproof as I'd hoped.
Personally never had an issue using the gravel version on my MTB but you can see how the new one has extra features including a side fold which improves the stiffness

so it was! but yes, no particular mention of it being a MTB rather than the Gravel/road type so I scrolled past as a 'use that and it's good so don't need to read about it' :-/
I have one winging it's way to me, but I also have an aliexpress 'version' on it's way as I needed a cheap top up to get discounts and free shipping on some other largely impulse buy bits.

I think the big difference is the location tbh, the win wing's completely out of the way and has no impact on riding, whereas for a lot of people the saddle mounted ones are intrusive. Win Wing can have better coverage too <if> the angles work, if you can get it close to the wheel and get a good angle it's way better. But equally sometimes it's probably not as good.

I've had similar happen. I recall rOcKeTdOg seemed to believe it was caused by user error when I posted about it, rather than the paper thin plastic being unsuitable for gales. Annoyingly that slightly damaged it the day after I bought it. Not a product I'd recommend if riding in strong crosswinds. Fortunately it's not happened since and has been great otherwise, so I've just ordered the mtb version to give that a go.

The gravel one certainly is, way better. My experience is that it basically intercepts crap coming off the rear wheel close to source, so your butt and the bike above, say, top/tube seatstay junction level stays clean. Below that you'll still get mud, but that's the pay-off for having a sleek, fast too fit and remove, mud thing.
It's also, for the same reasons, not something that will keep road spray etc off anyone who's drafting you.
If the mountain bike one works as well, it'll be great. I should probably buy one to find out, but it feels a bit like wishing for rain. On the other hand, not buying one feels a bit like tempting fate... 😐
Leave mine on the gravel bike all the time. have a second for road too which I mix and match with the Ortlieb Quick Rack (+ guard). The rubber straps have been excellent, and I've not seen any failures. Their biggest gravel update was moving to black stays, but I like my original grey ones because the bikes are Titanium 🙂
Bump for winter 2025/26. Any more feedback on the MTB-specific version of the Win Wing?
Ideally how it performs vs a Mudhugger rear. I've got more MTBs than Mudhuggers and they're usually permanently on for 6 months or so, but it leaves me with one bike without one - mainly because I've always struggled with fitment on that bike. Considering a Win Wing MTB for a bit of variety unless they're utter poop?
