Crud Roadracer Mk3 Mudguards

On first inspection, looks very strong, yet should provide all the protection required whilst riding in the inclement weather. Unfortunately, not yet fitted, so can't pass a judgement, will get around to it soon, I hope!

Crud MK3's

Much better than the old Mk2's. Easy to fit, less movement when riding & wider to accommodate 25-28 tyres. feel stronger too. Good product!

Sporting Road Mud Guards

Not the most exciting of products. However it helps keep you dry and the bike cleaner in less than optimum weather. I started to research what was available. I had the Crud Mk.2 model on my bike for years, but, unfortunately a small tree branch was kicked up by the rider in front and ruined my rear mudguard. Very few products available or suitable for my Carbon Trek Madone. Reviews were poor, videos on YouTube nearly put me off. But I realize that not everyone can follow instructions or use tools. Not that any are needed for this product, apart from a pair of scissors. So I prepared and fitted the rear mudguard. Fine, clearance with 23mm tyres. The front fitted fine. A blob of hotmelt glue secures the small plastic threaded bolts to attach the mudguard extensions . The mudguards went on without removing the wheels. Fitted and in use. I am fairly happy with the product. They fit, are not too expensive and they work. Just don’t always be put off by negative reviews.

Crud Roadracer MK3 Mud Guard Set

Awesome product, so effective, but yet so slick and inconspicuous

OK fenders

Was happy with how well they fit and function until on the 4th ride with them on the extension on the front fender flew off!! 5am dark and raining, extension never to be seen again. Cleaning the extension with the included wipes not enough to keep it in place.

Good fenders which required some work on them

Hi there. I've bought those mk3 for my road (race) bike. I wanna add some notes I hope would be useful. 1. I had forks with smaller distance between legs than was designed for mk3. Some people suggest to cut or sand out fenders in order to fit. I used hot air (soldering air gun, but you may use every industrial air gun) to make them softer and adjust the shape. It was a good idea, because the fenders kept their original stiffness. I also kept the front nose (many people throw them away). What I had to cut off was the small lover part of rear fender (as suggested on the product box) 2. I barely fit fenders to 25 tyres. Hence I am a bit sceptical about bigger wheels. 3. Velcro was good. You really have to properly clean the surface for them. 4. Attaching mk3 takes some time coz the clearance is tiny.

Light, Stiff, May require Alteration to Fit

First, well designed and constructed. The weak point for attachment (if any) isn't the "duotec" (rock solid once attached ... in fact takes effort to detach) but the adhesive layer between the "duotec" and the bike frame. That said the adhesive is quite strong. The claimed maximum tire width of 35mm is optimistic. While technically the fenders are (mostly) wide enough to block spray from 35 mm tires, the front of the front fender and centre section of the rear are much narrower. Also on one bike with 35 mm tires (Trek Domane Gravel) there wasn't enough tire clearance to fit the rear fender (the outside edge rubbed on the tire), On another (Trek Checkpoint), again with 35 mm tires, the fenders fitted, but the hydraulic disk brake hose running down the inside of the left leg of the front fork made it necessary to trim the "duotec" pad and the plastic of the stay. I have chosen not to use the brush pads (supposed to go between rim and fender) since they won't work with the wide tires. The protective pads provided don't appear to have any use so were ignored. That said, the fenders are on and appear quite solid. I haven't yet tried in wet conditions so can't comment other than to say they will likely provide at least moderate protection. I had hoped to be able to quickly attach or remove the fenders but that won't be quite as simple as I had hoped. All that said, subject to longer term confirmation, I'd give these a conditional recommendation, particulalry at the sale price I paid.

Not for Road Bikes

I was looking forward to the Mk3 as I've had a couple of the Mk2s before. The Mk2s were finicky to fit without some wheel rub on my Colnago road bike but once fitted worked a treat. I couldn't for the life of me get these to fit properly with 23mm tyres and the velco fixing adhesive is no where strong enough. These are now sitting on my bench and I'm considering throwing them out. In an effort to make these easy to install and remove, Crud has taken a backwards step with the Mk3s. Maybe they're great on a CX bike with plenty of wheel clearance but I wouldn't recommend them for road bikes.

pretty good but needs work

I put them on my Davidson TT cyclocross bike in the fall and commuted all rainy winter through spring, about 2700 miles. They function pretty well despite a strange rear fit owing to my tiny rear triangle with very low angle seat-stays and having a pully on the seat tube for my front DR with top-run cables. I did have to jury rig a bit with scissors and a bit of zip tie on the seat tube to fit my odd little bike. I had been running a seat-tube mounted MTBR type paddle, these are much much better on the back of legs and mechanics. Because of my low-angle seat stays the rear of the mudguard doesn't go down very far over the back of the rear tire so I do get a bit of a rooster tail as with the paddle so don't draft me in the rain. Also, the flexi nature allows some drops to sneak by but not horrible. The front extension is a joke so I augmented with glued plastic. The drop down the back of the front wheel is perfect. One thing I really like is that I can easily fine tune the spacing to fit any tire I use (28mm to 33mm road and knobbies) to minimize toe-strike, a real problem on my bike particularly with standard mudguards. That super velcro is crazy stuff, works very well. I wish the packaging came with extra to replace as I expect it will wear or come off eventually. One-size can't ever truely fit all so I do wish they made a couple different lengths and 'forms' to better suit. One does have to fiddle a bit to get it perfect. But they are overall quite functional, looks good (I think), reasonably easy, super light. I like them a LOT better than the MK2 I had on another bike which I ditched.

Tight fit but excellent product

I have these on my GT grade gravel bike. The fit is a bit tight with 32mm wide tires and I have some minor rubbing when travelling on uneven or bumpy surfaces. However I'm still giving these 5 stars for their ease of installation and overall great design. They look great and work even better. I would recommend these to everyone with 35mm wide tires or smaller.
