Daniel Easy to put on bike and great value.
Mr Hunt Great product at a great price. Was easy to fit to my Boardman hybrid, no issues. Best of all, its designed and manufactured in Yorkshire. Would strongly recommend.
Mr Lis Best I ever had!
Mr GUCER Install takes 5mins on a clean bike. Covers nearly every area that can splash water to you.
Ian I bought these to replace the Mk2 version I have used for several years. They are much easier to fit, more sturdy and provide a better coverage on the wheel. Wish I had got them sooner.
Mr King If you dispense with the supplied fixing system, these mudguards are light and thin enough to fit under a caliper brake Road bike. I used cable ties instead but had to drill holes.
Mr Roach Lightweight sturdy mudguards, once set up brilliant, really pleased
Mr Jackson Great item, very easy to fit look amazing on my white Giant Defy
Mr Meacham Perfect product. Cheap and reliable, does exactly what you need them to do.
Mr Lourenço Bom material, uma evolução em relação ao já bons MK2, mas com possibilidade de servir em todos os quadros
Iain Excellent solution, much more solid than previous versions, with much improved protection.
bryan The only guards that would fit my bike because of tiny clearances.. genius design.. attach with super strong velcro...Lots of videos available for fitting.. spare parts available from crud...
Mr bolton These mudguards work well once fitted and look nice and discreet, but they are by no means straightforward to fit. They say that you need 4mm clearance, but I would say 6 or even 8 and as a result of that, I couldn't fit them under my fork. However I just cut them short and run without the nose piece, not ideal, but I am getting most of the benefit. I had to trim a far bit off the rear one too, to fit it under my ( ultegra 8000) brake. It is never very nice taking the dremel to a brand new piece if kit, but be brave and they can be made to fit pretty well. No signs of the fixings failing either, and I have used them in some grim weather, including riding through a 12" deep flood!
terence Got these for my winter hack. Spot on and easy to fit. Bargain price in the sale too. As always great service from merlin.....defo recommend these.
Mr keyes these are second pair I've bought. They can be fiddily to fit at first but get better at it second time. They may need some cutting based on bike model. Glued on parts can break off easily but on the whole robust, keep water and actually look good. Easily removed for summer
Mr Eatwell First pair of road bike guards I’ve had and they are perfect. They were really easy to apply. If they start rubbing on the tyre then all you have to do is unstick them and adjust.
Mr John Simpkins I purchased these mudguards for the oncoming winter weather and this was one of my better decisions.I previously used a clip on butt protector which was ok but the crud road racers are like night and day! These keep you very clean and dry even your feet . They fit fairly easily but it does take a little time and effort. A few cuts and trimming is required but I did manage to keep the mudguards whole without cutting the ends off . They do tend to flap a little when riding but expected considering they are a temporary fix for winter conditions . All in all they are perfect with a little time fitting ( don't just try to fit in 10 minutes prior to your day's run) . 10/10 👍🏼
John Good quality and much improved fitting with secure Velcro type fittings. Would strongly recommend to others
Mr McDonald Quality product. Relatively easy to fit, if you follow the instructions, and can be removed easily.
Mr Martin Good product , be prepared to adapt them to suit the purpose you have by chopping bits off , but once done they do fit securely & don't rattle !!
Jonathan Works great! Looks great! Super tight clearance on 700 x 38mm tires but still just barely fits. Would've like if they had kept the length of the rear fender on the mk3 as long as the mk2 or at least had an integrated solution to extend the rear fenders length.
Mr Brink A good looking mudguards. Easy to install. At the rear wheel it was a little hard to fit with the caliper brakes
Mr Evans Fitted to my road bike on 700c x 23 tyres. They replaced Mk1 Mudguards which lasted me about 10 years before failure. New guards are simpler in design and a lot lighter. Set-up is a delicate process that took some time, but once complete, needs no further intervention and the guards are firmly fixed to the frame with no movement at the point of attachment (unlike my old ones). In action, they do a really good job, keeping muck off the bike and keeping my back and feet dry. I would have liked the rear mudguard to be a little bit longer but I like the fact that the back is the same as the front, so I can swap them around if one fails. Plastic on these feels potentially brittle. I don't know how they will stand up to abuse in the long-term. I think they are this way because the design requires more rigidity than my old guards, so the plastic is thicker. However, there is not a lot of choice for a road bike with no mudguard eyelets and I think these are the best solution if you want full wheel coverage. I really like them for their simplicity, minimal weight, and function., and they are also affordable. I also like the fact that they spring back to aligment after being leaned against something (my old guards didn't). I plan to fit 25mm tyres later and the guards look like they have plenty of room for even wider tyres. So yes, I would recommend them. Thank you Merlin for good price and service.
Mr Hellawell Very prompt delivery, and pretty easy to fit. It hasn't rained down our way since I put them on but they stay in place well while riding, with no rattles or additional noise.
Mr Miszczuk Quite good, would need additional strap for the back wheel, all in all my bike is a Bordman adventure so on the regular road bike they may fit much better. They look cooler than on the pics.
Mr sanderson Just what was wanted,usual Merlin service,easy to order,great price,propt delivery
David Great once I got them fitted. Can be fiddly to get in the correct position. The tail piece for the rear guard is not long enough and still sprays behind and up.
Clive Used these mudguards for a couple of hundred miles now, they do the job no problem. Had to trim the rear guard slightly where it runs by the front gear mechanism. Have removed them a couple of times to clean the bike no problem refitting. All good recommend.
Mr Sufana Fits well on my Cannondale SuperX
Christopher Fitted to my grandson`s Specialised bike after taking sometime to get the right position so the mudguards didn't rub. Otherwise easy to fit.
Clifford Look good, tricky to fit (as most online reviews and videos suggest). My bike has very tight clearance on the rear wheel; I have fitted only one part of the rear mudguard and secured it with a zip tie where the bolt goes to fix on the second part. However, it does the job of keeping road spray off my back. Versatile system, fits very tight clearances where rival products can't be used.
Robert This my second set of this product, both on Cannondales, a Synapse road bike and a SuperX force one. Both these frames have slender seat stays which could have been a problem as these mudgruards use velcro attached to the frame as the main support. I have found these to be excellent in action but fiddly to get setup. There are may bad reviews of this product but give them a go. The purists amongst you will worry about damage to the frame, but a dry bum is worth the sacrifice of 4 bits of velcro on the stays and forks , If I had a Pinarello Dogma...... ;)
Glenn FitzGerald Arrived quickly - one week from the UK and exactly as advertised. Easily fitted to bike (disc brakes) and have removed them until we have rain then will refit, which should not take long as velcro strips are already in place on the bike. What can I say good price, fast delivery and good product. First time shopping with Merlin and certainly will not be the last.
André Excellent! Easy to install, used it on 2 different cyclocross bikes. Glad I found them!
Mr de Tournemire Good product. Simple to fix, efficient for purpose
Mr Bonkowske These are easy to install and look great.
Mr Jarvis Installed great, look pretty decent. Rear fender could come down farther for group rides.
Daniel On one hand, these are an awesome design - really no complaints EXCEPT that the "velcro" aspect is too strong relative to the adhesive that attaches to the frame. Even when I first tried to attach one of the adhesive pads it wouldn't stick... like the adhesive was defective. On the first ride out in snowy weather it came off the frame... now there's no sticky left to it at all so I'm not sure how to go about reattaching the fender to my bike. Zip ties I guess? I had the roadracer mk2 and found them effective yet fiddly. These are much better if they would just lessen the intensity of the velcro or increase the adhesive - they're nowhere near in danger of the velcro being too light, but I'm afraid to even try to remove them now. Frustrating. Otherwise, great product. If you don't mind resorting to zip ties, buy them.
Mr savage Easy set up, great fit, light weight. Every bit as good as the 2nd gen version.
Dmitry It is the most useful addition to my Specialized Sirrus bike. I believe mudguards is a must for any road bike. Crud Road Racer MK3 are very functional, stylishly simple, and easy to install (no tools needed). My order was processed and shipped the same day. Delivered to the USA in 10 days. Thanks to Merlincycles for the great site and service.
Canadian Cyclist Must have accessory for those wet days. I can't even tell it's on when I'm riding with it.
Aidan Fitting is easy, and the Velcro system seems to work fine. I've fitted to a Cannondale Supersix and clearance is tight - there is a rubbing noise every time you ride through water as the tyres pick up debris. Front tip on front mudguard fell off on second use, so not sure about the sticky pad used to hold this on? Overall, they do the job but in hindsight I'd probably have bought another make with better clearance
RPS Love these fenders. Perfect for disc brake bikes with lots of clearance. They would fit modern caliper brake bikes, but would require some engineering.
Darren Great product - keeps everything dry and easy to install
Luke These are simply the nicest bicycle fenders on the market. Sturdy, well-designed, worth the cost.
Jono RRMk3 are easy to mount, have superb coverage, and are surprisingly light. The centrally placed mounting arms mean the tips tend to wobble around if the road surface isn't smooth, but that's an expected tradeoff for the reasonable weight and full coverage. Enjoying the product so far, but can't yet comment on long-term durability.
Tetsuya Best option for racing bike (as far as i have tried). Clean installation and doesn't damage the frame at all! Best part is the fender over the BB!
Diogo Kiss These mudguards are very cool! They have a very discrete and sportive design that do not affect the original look of the bike. I managed to install it even having a veeeery short gap between the frame/breaks and the wheels. I liked it so much that I bought 2 pairs (I have 2 bikes). In addition, it is worth to mention that it is quite firm even made of plastic and not having a metal support. It doesn't bother at all. Note: I took my bikes to a bike shop to have it installed because I don't have patience for doing it.
Sietse I was searching for some time for good lightweight mudguards that actually work. Not just a small piece of plastic on your saddle, but something that protects everything. This set is very good. At first I was afraid it would be too flimsy and wobble all the time, but that is not a problem. Tested them really good in moderate rain, but very wet road. My shoes where actually not soaking wet! Also the rest wasn't wet from below :) . Till now it works like a charm. Shipping to the Netherlands was pretty vast and good. Price was very competitive.
Mr Dörr Much easier to handle than the MKII. Did not ride in the rain yet, so I can not tell about the protection from wet streets.
K It is hard to get them precisely lined up if you do not have a lot of clearance. When the roads are dirty, they make a little bit of noise. But they keep you dry.
Kat Fortunato What a simple, elegant design. I haven't had the chance to take these out on the road in the wet yet, since I don't really care for very cold weather riding, but they hug my wheels perfectly, and I expect to be much drier this spring - important when you bike to work. A quick test holding my bike into the tub with my roommate working the pedals resulted in a fairly dry arm. The installation procedure was smooth and simple, aided by the nice big instructions printed right inside the box. I'd say it took no more than 10 straight minutes to actually get them installed. Fine tuning took a bit more time, as there is exceptionally limited clearance between my front fork and the tire. The rear guard went in smoother than chamois butter. My only strong suggestion is to watch the installation video first for an overview of exactly how it will work.
B Bike: Merida Scultura Disc Tyres: 700x28 Perfect, even in strong winds and in curves the mudguards do not cause any problems. A true road biker will mount them and not care about looks. A dry bottom/back and good health is far more important. With that said, as far as mudguards go they are unobtrusive visually on my greyish-silver frame. READ and RE-READ the INSTRUCTIONS before installing. BE PATIENT when installing and you will NOT regret it. Apply in a WARM room for best gluing performance.
Mr KARADAYI Very practical and useful, Not rubbing, I would recommend...
T For bikes without fender eyelets, I can1t imagine you could do much better. Easy to install, great coverage, and easy to pop back off. May rattle a bit over rough stuff but still totally worth it.
Mr Sirkia Works fine. Like the idea that I can take these off when I don't need them. Lets see how long these will last
davies Easy to install and remove and are a reasonably secure fitting, adequate coverage but could do with a bit more length at the rear, don't provide the same protection as the SKS mudguards fitted to my other bike which are a permanent winter fixture whereas the Cruds can be removed in seconds for the drier days.
JT in CA, USA Easy setup, excellent coverage, lightweight. I fitted them on our two bikes, but when we went for a long ride yesterday, I took them off, since the roads were dry. It's actually one of their strengths-removal took about two minutes.
Mr Gregory 10x better than MkII. Better coverage, better stays, better installation. On my CX bike, which I use as a commuter, I couldn't make the rear fit because of the canti bosses, so I used an old MkII rear on that bike. I will figure out a way around that someday. Fits road bike no issues. I wish they didn't require piecing together - would much prefer one-piece or maybe epoxy pieces together. I guess I could just epoxy them myself, but IDK which adhesive to choose... I wish it came with at least one extra set of duallock so you could move fenders between bikes. For the price they could afford to include a roll. That's another thing - the price seems awfully steep for what they are. OTOH compared to what? No direct competitor AFAIK. Overall I'm sufficiently pleased with these that I will buy more as needed. I will grumble about the price but I will buy them.
Ms Moseley A bit fiddly to put on, but otherwise does a good job. Currently only using the back one as my front tyre has a slight lip (which I'm sure will wear down eventually) that catches the front guard and makes an irritating sound. Have cycled in bad conditions without the front guard and was surprised how clean I still was!
Andrew Easy to fit, though as always seems to be the case some minor modifications were necessary (to make fit/ prevent rubbing). That said, it was easy to fit. Time will tell as to whether it's durable.
MellowJello Installation is a bit picky near the top of the calipers, but otherwise absolutely zero rattling once properly installed. Love it.
Inscoe Quite easy to assemble and set up. The fine tune adjustments were fairly easy as well. The ride is solid with the small exception of the extension piece on front fender - it slaps the front tire from time to time, but only when going over bumpy road. Obviously the easy fix is to give the fender a little more room, but I like less than an inch of space between tire and fender. So not a design flaw, more an observation about my own nit-pickyness.
Seb Nice fenders, easy installation and easy to take off again. I didn't wash my frame enough and the sticky Velcro didn't stick very good but it still works and spares are available on Cruds website.
Scott Very easy to install big improvement over the mk2. I do have reservations about durability only time tell, so far so good though
Mr Clash Very easy to fit, although the sticky tabs which attach to the frame to hold the guards in place aren't strong enough and came free during a ride. Used zip ties instead which are far more secure, and once you've got them free of the spokes they are fine.
Mr Vickery Great mud guards, feel quite solid and don't bounce around to much. I'd buy them again.
Mr Dutton It took a bit of fiddling to get them on, but still far easier that current alternative mud guards I tried. The quality of the product is good and so far I'm pleased with the result.
Mr Smith Great product easy to fit and effective
Mr Clark Installed but not ridden yet. This product looks like the best solution for race bikes with minimal clearance. I have a Cannondale HM Evo, SRAM red. Could not fit the front guard under the fork. No worries just cut it off short of the fork. The back guard fits easier but opted to leave off the added section that drops to the bottom bracket. Couldn't get the rubbing to quit. The stickers: stout little guys. I'm praying that my paint is still on when I hit it with a hair dryer in the spring. Wish me luck.
Molloy1313 I'm really happy with these. I was worried I wouldn't find a set of fenders that would fit with the amount of clearance I have but these have worked out beautifully. Im riding in New England winter weather, so having fenders was sort of a must for me. The fact that they are such low clearance also makes them look super sleek and sexy. If you're looking for decent fenders and your bike has at least 4mm of clearance between tire and brake/frame, then you need these. My only concern is the quality and longevity of the mounting pad/velcro. Mine came off the frame the first time I detached the fenders. I guess get it right the first time and then never take them off. Having a mechanic stand makes installation infinitely easier. Overall, I'm definitely happy with the purchase, although it seemed as though these were my only option.
Mr Marchment A truly excellent product. Having used Road Racer Mk2 before, needed something for disc brakes. Easy to fit, done in 30 minutes, no fiddling. Rode with them for 50 miles with no further adjustment required. The stays are not the prettiest design, but you can understand why they are that shape. Had used SKS longboards, but these destroyed themselves totally in one winter.
Mr Mabberley So far so excellent. Really easy to fit, no rattles, keep my bum dry and look good. I really only needed a rear one, so the fact that both guards are identical (apart from the extension pieces) means I have a spare if one gets broken. Agree with one of the other reviewers that the packaging is also very good from an environmental point of view with the instructions printed on the box, so no more lost "how to" leaflets in multi-langauges. Overall a simple, effective and aesthetic product. Should be entered for a Design Award.
bikeclub On the good side, the guards mount and dismount fairly easily and would seem to fit most geometries fairly easily. However, on the bad side, it is hard to get them precisely lined up and for them to stay that way. The rear fender has three solid mounting points which makes it more secure, but the front fender tends to fall out of alignment. My narrow carbon fork has about 5 mm of clearance, and the fender and tire make slight scratching noises when I ride through any dirt on the road and when the tire rotates -- the clearance is that tight. I'm hoping that after readjustment works better.
Mr bower What can you say about a product that does what it says, is very easy to fit and easy to interchange between different bikes. Another great product by the Crud team
Bamford I have had the MK1&2 and the MK3 is far more sturdy. Fit is easy and fairly simple. Only criticism is the rear guard doesn't go down far enough for following riders. Front guard goes further down so protects your feet more
Mr Dransfield Service from Merlin top class as usual. I bought these guards after seeing them at this years cycle show. Wanted wider ones to fit my boardman cx with 35mm tyres. (The gaurds state up to 38mm). Very robust quality. Only real problem is the clearances. The rear fitted well as the zip tie on the down tube gives it more stability, The front guard is a little more difficult as not as stable. Overall pleased with them. To solve the issue with the front guard I may go with a narrower tyre. ( 28/30)
Desombre Brilliant product for fitting to road bike frames which don't have holes for mudguard stays or have no room because disc brakes are fitted. Very easy to fit and remove just make sure the heavy duty Velcro is put on in the correct position first time. Great price and service from Merlin as usual.
Mr Mason I have not had them out in the rain yet. I cannot speak to their effectiveness, only to installation & adjustment. Because they have very tight clearance, I did have lots of noise anytime I went through Autumn debris. I am running 700 x 18 (old) on the front and 700 x 23 on the back. Installation on my '09 Synapse was not quite as simple as the YouTube video makes out, but definitely easier than my MK2's. I put the Velcro far back on the stays as you recommended, and have had a difficult time adjusting the rub out, & keeping them aligned, they are too far back. Maybe make the stay Velcro a tad larger? The front fender is plenty long, but the back does not have near the length to protect following riders, and maybe not long enough to easily add a flap. Thank you for updating these fenders. Your idea of quick release fenders is fantastic!...after many frustrating hours with the old school types. I was also very impressed with the economy of receiving these in the United States, <$7, and the short duration to receive, 8 days.
Mr Poirot Perfect item! Quick to install, stays in place, does the job keeping the bike clean with no rattling. And kudos for fast delivery to Brooklyn, NY!
Alan Hindley Once fitted, these are an excellent solution to the problem of attaching mudguards to a close clearance road bike. They work effectively and look good. But. I question the purported simplicity of installation. If you have a tight gap (within, but close to, the suggested tolerance ) be prepared for a longer install than the promotional activity suggests. Also. You may or may not admire compromises made to 'industrial design concepts' - e.g. same front and rear main units are the same, the two-part construction makes for low packaging costs - ideas which I admire, some might not.
Wade Quite impressed with these third generation Crud mudguards. Very easy to install and quick to detach/ demount. Have not fully tested them in the rain but they seem fit for purpose. My only criticism is the plastic from which they are made could be a little more flexible and robust...when reducing the length of the rear mudguard the cutting caused a small crack in the material which should not affect the overall performance but still this should not have occurred. Overall would recommend.
