Rock Guardz Carbon Mudguards

Rock Guardz Carbon Mudguards


If you’ve been reading Dirt lately you might have spotted a feature that we did on a great little company that we found called Rock Guardz. Basically the guy behind the company used to make carbon fairings for superbikes, and race them, but then he got into mountain bikes and he used his skills to make a carbon downtube protector for his bike. His mates then all wanted one, and then so did theirs, and from that hobby a business has grown. He now gets some of his Oswestry locals to help him make the custom guards as demand has grown so much, and now they’re even busier as they’ve developed this new range of front mudguards.

Each one is made by hand and there are a few different models to fit a range of forks, and the number of compatible forks is growing all the time (we’ve found they fit to other forks pretty well anyway). They’re also offering a choice of three different lengths as tastes vary, but all of them will work with 26″, 650b, or 29″ wheels. You might think that because they’re made from thin carbon they’d be useless in a crash, but we’ve twisted one well and truly and it simply pinged back into shape. Impressive. They’re incredibly light too, 70g for the short, 95g for the medium, and 111g for the long. You have to add in the weight of the four zip ties which you use to secure the guards, but even so they’re still bloody light.

When we first received the mudguards we were a bit unsure about the look of them, particularly the longer ones, but as soon as we mounted them to a fork we thought they looked great. Fitting them is dead simple and quick too, just four zip ties. These do a great job of holding it securely in place and there are no rattles. Because the guards are so thin mud clearance looks decent too, and Brendan Fairclough certain didn’t seem to be having any problems with the one he was using at the recent Combe Sydenham mud fest.

The added bonus of the design is that the arms which stretch downwards also do a great job of stopping filth getting onto your stanchions and seals. This should help keep your forks running smoother for longer. Of course there are other mudguard options on the market but we think these could well become our favourite. We reckon they look a bit classier than the other offerings and considering that they’re hand made from carbon we reckon they’re very reasonably priced too, especially when you remember that they’re made right here in the UK. We always like to support home grown products, and even more so when they’re as good as these. We also really like the fact that you can chose between several lengths.

By the sounds of it Rock Guardz might well have some more stuff up their sleeves too like rear mudguards that are custom made to fit different frames (like their original downtube protectors), and they’re certainly open to ideas too. So, if there’s something that you’ve always fancied but haven’t ever been able to get hold of then I definitely reckon it’s worth getting in touch with them. As long as it’s made from carbon that is. A gem of a company if ever there was one, and it’s made even better by the fact that all the products are made by a great bunch of people in their sheds. Keeping it real indeed.

Short: £35.50
Medium: £45.50
Long: £49.50

  1. Rip Off (haven't got clue)

    Nice DFender rip off

    1. Ed

      Ummm…not exactly. If anything it’s a Mucky Nutz rip off, but made from carbon rather than plastic. The only thing that makes it similar to a DFender is that it’s a mudguard. So is the DFender a rip off of the first ever mudguard?

  2. ste

    No. The DFender is a rip off 😉 and it fugly

  3. panzer

    50 effing quid!!!

    1. Ed

      Did you overlook the £35 one? And remember these are handmade from carbon in the UK, not in some Far East Factory where people are paid a pittance.

  4. David

    Do you know if they work with DT Swiss forks?

    1. Ed

      I don’t I’m afraid, but ask the guys who make them, and if they don’t they might well be up for making you one that does fit.

  5. SoWal_MTBer

    Have had two of their downtube carbon protectors on my rides. Great stuff! I’m sure these will be equally awesome.

  6. verga emilio

    Carbon fender is for unprofessional people, it could be cut the tire.

  7. Daire

    Nice looking buy I’d rather have my Mucky Nutz large fender that’s basically the same thing except with better mud clearance and for less than a quarter of the price. Nice bit of bling though if you can afford it.

  8. Andy

    Disagree to say carbon is unprofessional when ALL the best bike parts are made from carbon, stems, seat posts, levers but to name a few.

  9. woppy

    when you spend many hundreds ++++++ of pounds on a bike £36 on a guard to protect
    your fork seals,sliders + face splater etc .and looks this good.

  10. Maximilian

    Welcome to the new fender fad after Mr. Crud, THE and RRP. But frankly, the old piece of tube zip tied between crowns is about all we really need. I don’t doubt these guys, but there’s only one Mr. Crud and that’s about as cool a fender will ever get, period.


  11. Forums suck!

    It’s held on by zip ties?
    The dfender isn’t the prettiest mud guard in the world but didn’t you’re parents teach you not to judge a book by its cover? How many of you people have tried one? At least the dfender has a proper metal mount with silicone inserts to protect your precious forks, which you probably hardly ever ride because your all to busy talking rubbish to each other about products you’re never going to buy!

    Obviously a lot of time and effort goes into creating a product so give the guys a break, try things before you go moaning about it! If you haven’t got the money to buy it then smash an inner tube between your stanchions…but the build up of dirt on your seals will screw your stanchions!

  12. Battlestag

    Carbon fibre (especially wafer thin stuff) is really brittle. Hence why formula 1 cars disintegrate with the slightest knock. At least a floppy plastic one might bend a little in an off or while loading in and out of cars etc.
    Looks good though!

    1. Ed

      Did you not read what I said? We bent one of these rapidly through at least 90 degrees without any sign of cracking whatsoever. It simply pinged back into shape. And I must have done it about ten times to the same mudguard, and every time it behaved the same (I’ve only done it so many times cos people have come into the office, seen one, and then said something along the lines of “nice, but I bet it would snap easily”, at which point I then proceed to bend it like hell…and then they say something like “wow”).

  13. wacko

    I’m a reader from the East Coast of the US, so this is practical, but I’m wondering about the size; for DH, would you suggest medium or long? (Fox 40 on an Undead)
    Any and all input would be greatly appreciated as I like this design, but don’t want to order the wrong one.

    1. wacko

      p.s. how do you feel this compares to the DFender? Is it worth the extra money? I like supporting home-grown products, but privateer racing is at time about budget balancing.

      1. Ed

        I’d go for a medium, I think the long is a bit overkill.

        As for comparing it with the DFender, I personally prefer this one. It’s a lot lighter and I think it also looks a lot neater. The fact that this one also stops mud from getting around your fork seals is another added bonus. Of course both do a great job of simply being a mudguard. Yes the zip tie fixing on this one might eventually cause some marking on your lower legs, but then if you’re that worried about that kind of thing then you probably wouldn’t be throwing your bike down DH tracks. Still, if it really worries you, you could always put a bit of clear protective stuff underneath.

        Oh, and price wise aren’t these cheaper than the DFender? That is listed as £49 on their website.

  14. Slam Man

    why do you think mtb have never had mudguards?? they clog up. these are great guards if you want to pose and ride in the dry or rain but mud! “MUD”Guard it is not!

  15. dipsee


  16. james

    i think ill stick with back to back marshguards. same as and cheaper and they fit any fork

  17. Idiots

    *sigh* Why do people that have never used one bad mouth them? If you’ve used one (like the Dirt crew or I) then you’ll know that they’re strong as, don’t really affect clearance and keep all the crap out of your face. A Marsh Guard doesn’t even compare; the difference between a Marsh Guard and a medium Mudguardz is night and day.

    1. wacko

      Ok, that’s what I wanted to know – if it was worth the extra over a March, and how the sizing compared.

    “Slam Man”
    Have been running one of these guards for about four weeks and most of that time has been spent riding in very muddy and wet conditons. To be fair my guard has done exactly what it says on the tin (protected me from mud, snow and water).

    As for strength my bike travels around on a roof mounted roof carrier with the front wheel removed, it’s still like new even after several trips. It’s make a change to find a product that is made in the UK, and having been shipped halfway round the work.

    1. Slam Man

      great, i’m glad it works for you. but put this in front of gloopy sticky mud that sticks to a tyres and watch it clogg! this is a fact we discovered 40 years ago, look at MX bikes, why are they so high away from the tyre, why were crud catchers evented? yes they work if the muds loose and wet. and yes they will work if your mud is gritting and not sticky. it looks ace but thats all

  19. David

    I like the idea but one of the big problems with these and the mucky nutz guards is they make loading bikes into a car hard work, especially when you have a few piled up.

  20. The+butcher

    I’ve been testing the cheap o equivalent (mucky nuts) on my cross country bike. Very disappointing to be honest. Kept getting covered in all sorts of shite!
    Not a patch on the powa fenda……

    1. Dan

      Hmm that’s curious, I’ve used a mucky nuts for at least a year now and I do say it’s done nothing but good. It hasn’t stopped all mud but enough you can see my face is cleaner after a muddy ride

  21. NWMUD

    Ed, how do these fenders work with an over the tailgate of a pickup truck shuttling setup? Do they get in the way or bend? If not, these look like a great option

  22. Rupert

    If you feel the need for a mudguard, this looks like a good bet and supporting a small UK business in our homogenised industry is an admirable thing to do. If you don’t like mudguards however, don’t comment, your opinion is irrelevant here!

    Carbon always gets people talking, but knowledge is thin on the ground. That’s for good reason. Carbon is complicated and only part of the story. There is some truth in all the chat you hear from manufacturers about technique and layup etc. Carbon more than any other commonly available structural material is dependent on design and manufacturing processes to give it’s characteristics. Done well, carbon will outperform plastic and all other materials where it’s use is appropriate (it’s a shit bearing for instance). Done badly, it’s worse than most materials. You can’t judge from a distance.
    I once saw the inside of a Boardman road frame in the Rapha Sharp team pits. The dropout junction with the seat and chain stays was nice and smooth on the outside, but an absolute abomination on the inside. About 1/4″ thick in places and fibres sticking out all over the place – bad Carbon!

  23. bedders

    there was an interesting article in one of the magazines (might’ve been MBUK) about a year ago about which style of guard works best in different conditions and speeds. I can’t remember the detail but there was something about if you’re going fast you catch up with the spray and effectively ride into it, meaning one style of guard will be beter than another. Perhaps this is why different people find some guards better than others? Aesthetics certainly come into it as well I’d have thought…

    Ian is a cool guy, got a rockguard made for free for my YT Tues and bought a mudguard
