Our resident staff writer, Jack Luke, is a self confessed accessories nerd and mudguard evangelist. After spending years wrenching filthy bikes in the inclement climes of his native Edinburgh, he became a fully-fendered-dork and has been pushing the dry bum agenda for years — and he continues the good fight here.
Mudguards make sense for a number of reasons. While running your bike be-fendered will keep you and your kit much cleaner and drier, mudguards will also protect your bike from the worst muck, hugely extending the life of your components.
On longer rides, the boost to morale of being dry and comfortable on your bike is also immeasurable. A few audax events and randonneuring bodies even require your bike to be fitted with mudguards as a courtesy to other riders in a bunch.
As with seemingly everything in the cycling world, choosing the right mudguards for you and your bike isn’t always the most simple task. But worry no longer as our guide below should demystify the world of keeping dry on a bike.
The first thing you must ascertain is what kind of mudguard your bike can run.
If you’re bike has eyelets (or braze-on’s as they’re also known), you should be able to run full length mudguards.
Although these are a more permanent fixture, they are undoubtedly the best solution as they give the greatest level of coverage possible, are far less prone to wobbling and tend to last longer than clip on solutions.
If your bike doesn’t have eyelets, you may be able to use p-clips as a makeshift solution, though be cautious doing so on carbon frames.
Although the situation has improved greatly, the placement of eyelets on some bikes can leave you wanting (particularly on bikes with disc brakes), so a little bit of jiggery-pokery including bending stays may be in order.
Though some will bemoan the permanence of full length mudguards, they can look excellent if ‘integrated’ with the bike and really don’t take long to remove once set up.
The choices available for full cover mudguards are huge and we’ll cover these later.
Non eyelet solutions
Fret not if you’re bike is lacking in the eyelet department as there are other solutions out there.
Mudguards like the SKS Race Blade Pro and Crud Roadacer use o-rings (though MK3 of the Roadracer use a special kind of ‘super velcro’) wrapped around the frame to provide a relatively secure connection in lieu of eyelets while providing a level of coverage comparable, but not quite as thorough, as full length mudguards.
Although their light weight and sleek looks may seem appealing, be warned that this style of guards are often a bit of a faff to set up and tend to wobble about more than full cover guards.
However, if your bike has especially tight clearances or lacks eyelets, these are the best option available.
Clip on mudguards
Clip on mudguards are your last option and give the least amount of coverage of all the styles.
Though they’ll go a long way to stop the cursed brown streak of muck up your back, they’ll do little to protect your bike from the elements. However, for mountain bikes or those that absolutely cannot stand the idea of full cover mudguards, they’re the only option.
Usually mounting under the saddle, crown or downtube, these will protect you from the worst spray and are best suited to mountain bikes.
Which full cover mudguards should I buy?
The world of full cover mudguards is hugely saturated and there are lots of options to wade through. First, it’s worth considering what you want your mudguards to be made of.
Starting at the high end, a nice set of alloy, full cover mudguards are a very worthwhile investment that will last far longer than a set of regular, plastic guards.
Not only do they look handsome, but a set such as these Velo Orange mudguards only cost about £15 more than a set of regular, plastic ones.
SKS bridge the gap with their chromoplastic guards, which sees a thin layer of alloy sandwiched between two layers of plastic, creating a durable and sturdy set of guards at a relatively low price point.
Coming in nearly every size imaginable, the Chromoplastic guards are the usual go-to option for bike shops, with SKS providing a plethora of spare parts.
Lastly, a set of plastic guards such as the NCS range from Bontrager are a lighter option, but in our experience won’t last as long as others.
Secondly, consider what width of mudguard is most appropriate for your tyres.
As a general rule of thumb, it’s best to err on the side of caution and fit the widest set of mudguards you can to your bike.
Not only does this future proof your mudguard choice, but it also increases the clearances between your mudguards and your tyre, greatly reducing the chance of something getting stuck in there.
On that note, SKS includes breakaway clips with its mudguards which are designed to disconnect the stays of the mudguard from the bike in the event that something gets stuck between the tyre and the guards, stopping you from taking a flyer over the bars.
Be aware that the profile of some mudguards won’t play nicely on bikes with tight clearances, particularly around the fork crown so it’s well worth doing some research online or popping into your local bike shop and having them fit you a set that they know will work with your model.
