Installed the 42mm on a Sirrus 3.0. Rear installed very easily using existing holes on the frame. Front was a very tight fit to provide as much clearance to the tire to prevent it from rubbing and was mounted using the plug and play adapters.

Love these mudguards, easy ro instal quiet and excellent coverage which is quite rare

I mounted these on a Diverge size 58 with 32mm tires. These are excellent and look magnificient on my grey bike! I installed them myself with little fuss (I had to pierce a hole for the top attachment) and stay put very well using the mounting holes in the frame (you may need to buy the disappearing screws) and have transformed by commutes: now I enjoy riding in the rain more than before. The attachment of the stay to the fender is a little piece of plastic that cn break easily if you overstep the pedals: it would be good if the mounting HW included at least one spare for the breakabe parts. I had bought other fenders from another brand that did not fit well and did not look so nice. Glad I found these: I would have never thought a bike with fenders would look "sexy" but mine now does!! :-D

Well engineered and installs quickly and work well even in very wet conditions.

The design is not good and the construction is flimsy. I had these professionally installed too. The slim parts that hold onto the bike require perfect precision. Everything is held together by tension and a tiny PLASTIC piece on either side of the tire. The extremely low desin in the back makes it very difficult to navigate any terrain that isn't perfectly straight, perfectly paved roads. Hit a small patch of dirt or gravel, fenders caught. Picking up the bikes over curbs, the fenders got caught. Carry upstairs, fenders caught. Had some construction on the road and had to bike up those temporary ramps they build, fenders caught. They caught so often eventually I modified the parts to hang less low to the ground, and even then they broke in less than a year and now rub my tires terribly.

Great instructions! works well. !Very nice fenders’ ! look nice on the bike keeps the water off your back just overall a very nice set of fenders it must have!

Instructions were a bit vague. An improvement would be how to install on Specialized models not just generic instructions. Rear fender has small clearance toward the front but a large clearance at the back on a large Cirrius x 2.0.

Excellent full coverage fenders. Longer than most. If you've installed fenders before, then these are no different. The first setup takes some time, but once installed, they are rock solid and extremely effective. Definitely some of the best fenders I have ever used.

Don't bother. Waste of money. Bought these for my new Diverge E5 comp. Both are a big disappointment at the moment.

Need to take to a bike shop. Rear fender good luck. Who ever put the install instruction sheet together, needs a rethink.

These fenders fit my Diverge just right and look great. I haven't tried them out on a wet trail yet, but they have ample coverage and should do the trick. Download the instructions and skip the bike shop.

When I ordered the fenders, I was told that these fenders were made to fit my Specialized Diverge. But, I had to make several several cuts and bends to the fenders to make them fit and I then I had to engineer additional custom brackets to secure them in place. This is work I my local authorized Specialized dealer is not capable of providing. To my knowledge Specialized does not make a fender or mud guard compatible with the Diverge. These were my only option so I made them work.

They are impossible to install without professional help from a bike shop, but once installed they work great!

I don't know if I would recommend them because it is the first time I buy fenders. BUt they were easy to install requiring not so many modifications.

Bought these because they are what are recommended by Specialized for my bike model (Sirrus X 3.0). They barely fit and were incredibly difficult to install. The design makes it very challenging to install on the rear wheel properly so that the tire does not touch the fender. DO NOT BUY.

Specifications provided are confusing 42mm is NOT width of fender , apparently for (max.) width of tyre? Not compatible w. older specialized models (source). Missing rail for cable for rear light. Return and reimbursement without problems

After unsuccessful attempts to connect with Specialized support, I went ahead and purchased the 42mm fenders for my Vado 4.0 SL. The Vado SL comes with 700x38s. The instructions are not great - good pictures but poorly written. Which screws/adapters to use are depend on your bike. I had to drill a hole in the rear fender to attach it to the seat stay (bottom hole). It worked, but drilling in the correct place is tricky as the fender has to be "compressed" to meet the seat stay, but is uncompressed when drilling. Fender alignment is tricky, as the front may not be centered over the tire, when the back is. I removed the flexible plastic extensions on each fender. The extensions are ~ 9 inches, and while they make the fenders more effective, they still have good coverage without them. This saves a bit of weight and I the fenders look sleeker. Overall, if you have a Vado SL, I recommend the dry tech option if you just want to add fenders.

Keeps me dry as name describes. Even though deep puddles. ____ Most fragile part is the plastic bracket for fender stays. Breaking with rough bumps. (Zipties fix -or- call specialized directly for FREE parts kit) ***only lasts me a few months*** plastic plates snaps within 2k miles I would prefer alloy pieces _____ Setup is straight forward for rear wheel. (At most, when using plug-play = bending stay rods for cleanest setup) Front fender takes unique engineering. On sirrus bike left rod catches on brake caliper. (Must bend awkwardly) or (use plug-play adapter with standard brace = offsetting attach point dropping, "locking" the QR. wheel removal must fully remove skewer) _____ for rear fender I drilled out bridge rivet mounting/screwing to bike. Then snapped fender onto same bridge bracket. (Screw adds a gap = but fender remains stronger and more customizable)

The hardware that came with these fenders do not fit into the holes on the frame of my Specialized bike. The thread size or pitch is off. Useless.

These were supposed to be "plug and play" fenders for my Sirrus X Comp Carbon, but they were not. I couldn't get them to fit. The local bike shop was able to barely fit them by modifying them (notching out the front fender to get it to sit up in the fork). It was such a tight fit even then I had to drop down a tire size. They're also incredibly long, the bottom rubber bit hits on a lot of stuff, I haven't had them in a rainy situation yet but I'd guess they will have excellent coverage. I'd rate them pretty good if they were truly plug and play, as it is, they're just OK.

Covers a lot of wheel and protects the other parts well, especially when crash. It did absorb all the damage and didn't break.

A bit fiddly to install still making small adjustments,but overall it does the job

I found choosing the right size on the website difficult; the product was very poorly packaged; the fixing instructions are not easy to follow; the fixing process is fiddly; but they finally look OK.

Fenders were a huge pain to install, ultimately requiring me to use zip ties to keep them in place without rattling. One of the brackets ended up wearing a deep gash in the paint where an edge rubbed against the frame, and the clamps holding the supports to the fender broke. Worst part is that now I have to go through the painful installation process AGAIN to remove them. Absolutely would not buy these again.

I purchased the 42mm wide version for my Creo SL Carbon and am delighted with this product, especially the length which keeps me and anyone following clean and dry. They are fiddly to fit but worth taking your time to fit correctly.

Loving these on my Diverge gravel bike. Can’t believe how well they work!!

A bit tricky to mount on carbon frame with no bridge on the rear seat stays but manageable. Once mounted work good and quiet.

Really bad fastener system. It’s just not very durable and it’s a pain to install. Would be fine if the fasteners didn’t randomly loosen and break. Tighten them enough and they get easily stripped. I would avoid these.

A little finicky to adjust properly but when dialed, work great

I ride in wet and dry weather so these were a solution to prevent being tire washed during wet rides.

They give good coverage and look as good as any fenders can. But due to their long sections they rattle.

2006-2007 Sirrus: 35mm fender fit on 32mm tires. Mounting hole is vertical, had to drill. Marveled at the build quality and scratch resistance of the fender. Fork crown lock nut is not compatible, substituted with lock nut from Specialized Pizza Rack. 2020-2021 Crossroads: 52mm fender does not fit on 45mm tires. Vertical clearance is 6mm between the mounting holes and the tires without the fenders. A minimum clearance of 6mm is recommended including the fenders. You will need get smaller tires and smaller fenders if you are committed to this installation. Rear mounting hole is also vertical. Conclusion: Would be nice if Specialized made purpose built fenders for specific bike models rather than claim a universal “Plug + Play” standard where compatibility is based on random chance. These are a nice side project for people with a lot of tools and a lot of time. For everyone else, a raincoat is easier.

Nice hardware and an unmatched sleek look for road or gravel. I have no rattles or loose parts with these using 35 mm set with 28mm tires. Buying a spare set just in case availability becomes a problem. Very pleased with this set of fenders.
