Mucky Nutz Butt Fender

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.

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.

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.

Saves you back from all the mud/water/grit that would be thrown up otherwise in a clean and tool-free method. What more can you want?!?

Incredibly easy to install. Covers the width of my 29" inch wheels very nicely. Flew down a few hills at high speed through piles of wet leaves and kept my rear end completely dry and mud free. My rucksack did get spray as the fender isnt really long enough to cover too much of the wheel. But at the end of the day its not designed to protect your bag is it! Only downside is that with it sitting so close to the seat you do tend to catch it on your leg when mounting the bike but other than that very good product so far! Ideal for road/curb riding to work

Great little product to stop your bum getting overly muddy and wet. Doesn’t stop all spray but greatly reduces it. Good value for money

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!

Does its job. I'm still getting a little spray up onto my backpack but keeps my cheeks dry. Really easy to fit but would recommend a pull tie to secure it a little against theft.
