At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The SKS Race Blade Pro XL Stealth Series Mudguard Set has adjustability that is quick and easy to dial, and is impressively effective at keeping you dry both front and rear. They're not long enough if you ride with others, though.

With an exhaustive capability for adjustment, these mudguards work well across a range of road and cyclocross bikes – even those with disc brakes and aero forks. This versatility is what makes them a must-have.

The Pro XL Stealth Series (which is matt black instead of gloss) does a great job keeping spray and grit off your own kit and bike, but less so for anyone following, such as my partner who was hugging my wheel and complaining. I couldn't really ignore his moans when greeted with his mud-splattered face at the end of a ride...

I'd warn against using these on club rides – especially those with a mandatory mudguard rule (which is most I have come across).

But for solo dashes, for riders who own a range of bikes that may not have integrated mudguard mounts, these clip-on mud defenders are ideal. I found these a particularly useful addition to my race bike on mucky days.

Despite the temporary fitting, they're sturdy and don't rattle. That said, I did see some scuffs on the rear brake caliper on my rim brake bike and on the chain stays of my disc brake bike, so they obviously do move.

I would very much suggest adding helicopter tape, not only where the guards are mounted, but where the edge of the guard can hit the frame.

Suitable for tyre widths between 25mm and 32mm, the Pro XL is 565mm long at the front and 730mm at the rear. They don't stretch lower because the guards need to remain stable even with the non-permanent mounting system.

The initial set up, with four bolts on each side, is slightly fiddly to perfect. Two bolts adjust the angle while the other two adjust the length of the struts. It works well; you just need to set time aside to do it properly when first fitting to a bike.

(Top tip: instead of doing all the bolts on one side and then the other, I found it easier to get the guards symmetrical by doing the lower bolts on both sides, and then the upper ones.)

Once the hinges are set up, the quick release rubber straps allow the guards to be quickly removed and mounted. One pull on the rubber straps and they are off. There's no need to readjust when you remount them.

Price wise, the Crud Roadracer MK3 guards are considerably cheaper at £39.99 and are even quicker to put on, plus they take up to 38mm tyres across a wider range of widths. On the downside, they aren't as stable.

If you want fuller coverage, the SKS Raceblade Long set is available for the same £54.99 price as these (and not £45, as they were when we reviewed them in 2016).


The SKS Raceblade Pro XL Mudguard Set is very effective for solo riding, is very easy to mount/remove, and proves sturdy enough. The extensive adjustability means it is possible to set these up on a wide variety of bikes, too – just make sure to add some protective tape first.

For clip-on temporary mudguards these provide excellent protection and, although they aren't the absolute quickest to set up, mounting is easy and is fast after the initial adjustments. They're sturdy and don't rub, either – so long as you're riding alone, they're excellent.

If you don't have clearance for more traditional mudguards, then the the way the front stays on these terminate in a big lump of plastic on top of and behind the guard means that they foul the frame. Did for me anyway 🤷‍♂️

Lack of m/guard in front of the fork means water sprays forward and back at higher speed and means front of legs etc get wet anyway. 

These seem very good though especially for disc brake bikes with no caliper brake holes (like my 'dale Synapse).

SKS Speedrockers appear to solve this problem, depending on clearance between your seat tube and rear wheel.  A slightly less elegant solution is to stick something like this in the arch of your front fork, although that also depends on clearance.  On backwards (so the longer end points forward), it keeps mud and water off my legs, body and face.

On my Synapse I fitted full guards by using some P-Clips where the eyelets should be, then some zip ties at the fork crown and seatstay bridge. The only really awkward point was the bottom bracket, but an elaborate web of zip ties sorted it in the end. Not ideal but it did mean I got a nice dry ride on my 'good bike' during winter.

That's a good solution you have and I have done similarly  3
