Just got myself a Trek Farley fat bike. Great for riding round here but not so great for keeping my arriere dry.

The only rear mudgaurd I have seen is the Mucky Nutz but that looks somewhat short.

Any of you fatties use a rear guard and if so which ones?

I was just wondering if the new MTB Win Wing might keep the worst off me while on my Calibre Dune 🤔

I think maybe because it's a bit different looking I maybe don't notice quite how awful mudguards look, although I know it's not fashionable to care at the moment.

I did read on here the other day, someone complaining that a rear guard made all the crud drop onto their rear mech and cassette though which may be a valid point about them. Never really used them to be honest, but the never ending rain since the world started to end is making me rethink that a bit.

I use SKS fatbike specific, expensive but excellent. They are quick to detach and so far have withstood a year of my lack of ability crashes!

Enjoy your bicycle, they put a smile on everyone’s face.

Edit.. SKS Fatboards

Thanks. They look good. £25 if you trawl the interweb.

I have Mudhuggers front and rear. The rear has the extension for wider tyres and needed some coaxing with a hair drier to get it wide enough for 5" tyres. Works great though.

The front works well on rigid forks but it's a bit too close to the tyre when fitted under the arch on my Blutos. That can result in a lot of additional drag when the gap fills up with snow.

I have been trying a mudhugger rear but there is minimal clearance between wheel and frame so I will have to chop it quite brutally. 

Rigid forks and I won't be anywhere near deep snow so that's a possibility.

Mudhugger , but stretch with a hair dryer or paint stripper. Image is of a 5" surly ice cream truck so they definitely fitDSC_0134.jpg

Yes. I was toying with doing that...after I've butchered it.

I have mudhuggers on mine but not totally happy with them- it took a lot of heatgunning to get the front to fit (they're very shaped at the arch) and the rear is pretty flappy. It wasn't just a case of "reshaping", I basically had to melt the thing. And the fitting isn't brilliant though that's also fork specific 

Fatbikes can throw so much more crap and water, you really need a good mudguard

Thanks. My forks are rigid so I don't expect many problems there. It's the rear that's the problem.

Mudhuggers here too, on an old On-one fatty with Mastodon fork.  The rear is widened with the add-on extra bit and is indeed noisy but effective and worthwhile over a 4" FBR tyre.  The front is wider, as the suspension fork has sufficient room for both a 4.8" FBF and the Mudhugger front cruddie... and speaking of which, I've a classic Crud catcher on the down tube too, as I found the front Mudhugger isn't long enough on its own.  

Another advantage of this type of front mudguard is that they seem to keep a lot of the muck away from your fork seals, extending service intervals and delaying replacements.

Fatties really do throw a lot of muck about.

I thought I had a set of Mudhuggers but it is a rear Mucky Nutz and that is somewhat hard to fit. I cannot see fhow a heat gun will adapt it. 

I'll get some Mudhuggers and try them.

Think I've sorted it.

I was only looking at the rear - no wet arse for me - and had a Mucky Nutz lying around.

This just wouldn't fit in between the seatstays and the seat tube. So the dremel came out and chopped most of the protruding piece off. Then the heat gun persuaded the brackets to change shape so that they matched the seat stays. Bingo. It works.

For some reason I cannot post pics so you will just have to take my word. But it fits and I will test it tomorrow.

Thanks. My forks are rigid so I don't expect many problems there. It's the rear that's the problem.

 

So that was the exact problem I had 🙂 I think maybe they're shaped for a Bluto or something? But they're pretty square, as standard, and my fork is pretty rounded as rigids tend to be.
