Mucky Nutz Butt Fender

Couldn't be easier to install and does a good job of keeping the majority of dirt away. It does rotate slightly during the ride but this does not reduce its effectiveness. Overall I am very happy with it.

I recently purchased this small mud fender for my bicycle and have been generally satisfied with its performance. The mud guard is easy to install and fits securely on the back wheel of my bike, effectively blocking mud and debris from being flung onto my back and backside while riding. One of the things I like most about this mud guard is its compact size. It is small enough to be unobtrusive, yet large enough to provide effective coverage for the back wheel of my bike. It also has a sleek, low-profile design that doesn't add any unnecessary bulk or weight to my bike. In terms of durability, the mud guard has held up well after several rides through muddy and rocky terrain. It shows no signs of wear and tear, and I expect it to last for many rides to come. Overall, I am satisfied with my purchase of the small mud guard. It does a great job of keeping me clean and dry while riding, and I would recommend it to other riders who are looking for an effective and affordable mud guard for their bikes.

This is the third MuckyNutz mudguard I've bought (see my other reviews) - all are very lightweight and pliable and unlikely to break. This is the easiest to fit because it just clips into the seat rails, although it's easier said than done. I added a tie wrap in case it gets dislodged and goes flying without my noticing. Because it slants down towards the back it doesn't get in my way when sliding back over the wheel for manuals, drops etc, and it doesn't interfere with my drop post. It seems to stop most, if not all, of the spray from the seat upwards, though I haven't given it much of a stress test yet. It weighs next to nothing and is very reflective, as you can see, though I can't see much of a use case for that. Doesn't look as cool as the other MuckyNutz mudguards, but I prefer practicality over cool any day!

Certainly reduces some of the muck on my shorts and an improvement in overall reduction of dirt on my back. I did not need much more than this and they are easy to fix and remove

It's well made and tough, but almost too clever... It might come down to seat design but personally I found it a pain in the neck to fit securely, and even harder to take back off again. Functional, cheap, and well made but expect to spend a few minutes swearing at it.

Easy to fit/remove - keeps my rear dry. Good investment.

Overall a clever design makes fitting easy and stays in place well, reduces (not eliminates) mud spatter, small unobtrusive for those that don’t like the look of a full mudguard. This style of rear guard is good for off-road, where you expect to get covered in mud, it reduces the amount of thick mud you have to sit in and on your butt, but don’t expect it to eliminate mud spatter up your back, especially on road, as at higher speed more water/mud will be thrown up higher and forward over the guard, for that you obviously need a full size mud guard. It sits high under saddle, so does get kicked a bit but has stayed in place well so far. Not an issue with a dropper post, but could get in way a little on steep descents without, when manoeuvring off back of saddle, although it is very flexible. Only small criticism is it’s a little over priced, for what is after all a flat piece of plastic.

good gaurd . flexible enough that the odd kick when getting on the bike doesant break it
