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.
Fits well on my Cannondale SuperX
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.
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.
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...... ;)
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.
Excellent! Easy to install, used it on 2 different cyclocross bikes. Glad I found them!
Good product. Simple to fix, efficient for purpose
These are easy to install and look great.
Installed great, look pretty decent. Rear fender could come down farther for group rides.
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.
Easy set up, great fit, light weight. Every bit as good as the 2nd gen version.
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.
Must have accessory for those wet days. I can't even tell it's on when I'm riding with it.
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
Love these fenders. Perfect for disc brake bikes with lots of clearance. They would fit modern caliper brake bikes, but would require some engineering.
Great product - keeps everything dry and easy to install
These are simply the nicest bicycle fenders on the market. Sturdy, well-designed, worth the cost.
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.
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!
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.
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.
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.
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.
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.
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.
Very practical and useful, Not rubbing, I would recommend...
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.
Works fine. Like the idea that I can take these off when I don't need them. Lets see how long these will last
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.
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.
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.
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!
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.
Installation is a bit picky near the top of the calipers, but otherwise absolutely zero rattling once properly installed. Love it.
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.
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.
Very easy to install big improvement over the mk2. I do have reservations about durability only time tell, so far so good though
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.
Great mud guards, feel quite solid and don't bounce around to much. I'd buy them again.
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.
Great product easy to fit and effective
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.
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.
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.
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.
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.
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
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
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)
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.
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.
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!
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.
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.
