Mudguard Guide

Why use mudguards?

Mudguards help keep you warm and dry in the wetter months while also protecting your bike from mud, grit and spray.

This can dramatically cut down any maintenance needed to your bike through the winter. For commuters they are essential, road cyclists will enjoy the dry, comfortable feeling while not spraying any friends behind, and mountain bikers will cut down spray and mud to the face, eyes and back. Warm and dry cycling is simply more enjoyable, meaning you can ride longer and more often through the winter.

What type of mudguards will fit my bike?

For commuters, road riders and general cyclists the first thing to look for are eyelets or attachment points on your frame and fork. If you have the eyelets then a traditional full-length mudguard can be fitted. There are different widths of mudguard to suit your tyre width. There are many combinations of wheel size and tyre width available, look on your tyre for these sizes and choose the appropriate option.

“Ass Savers” and “Enduro Guards”

When you need a quick solution, these light and unobtrusive mudguards make a great choice. The “Ass Saver” style clips into your saddle rails and only take seconds to take on and off, they help stop a soggy bottom on an unexpected rainy day or when the road surface is still wet. The “Enduro Guard” style for your fork is intended for mountain bikes and is often left on year-round, while you do need a couple of zip ties to fit, they are fit-and-forget and help keep spray and mud away from your face.

Full-length mudguards

If your bike does have eyelets then full-length mudguards can be used, these offer the best protection for bike and rider from the elements. They do take a little longer to fit as they are so robust. Some longer types have additional mud flaps and reflectors built in.

To find the right size, simply select the option that suits your wheel size and tyre width. As all bikes are a little different, full-length mudguards are adjustable. This does take a little time, and sometimes the stays must be cut to length. But once in place, full-length mudguards will offer the best wet-weather protection available.

Clip on mudguards

Performance road and hybrid sport bikes with no eyelets for mudguards can use a clip-on type. Most performance based bikes that do not have eyelets will have very tight clearance between the frame/fork and tyre that does not allow a full-length mudguard. While clip on mudguards offer a lot of protection, they are limited by the performance nature of the bike. Clip on mudguards simply strap around the fork leg and rear seat stay to offer a good amount of protection from the elements.

Mountain bike mudguards

Mountain bikers can keep riding through the worst of the winter weather with fork arch mounted mudguards and rear mudguards mounted to either the chainstays or seatpost. With sizes working well with 29ers and rear chainstay mounted guards pose no issue with dropper seat posts.

They might not be the most glamorous of accessories but staying dry will keep you warm, meaning you can stay out longer and ride more often. Being able to keep riding through the winter will keep skill and fitness on point for when the trails and weather start to dry.

Fitted with zip ties they are strong and stay in place with minimal fuss.

Mudguards are essential to keep riding through the winter, with many different types there is a wet weather solution to almost every bike. Road cyclists will be able to keep training through the worst of weather and riding friends appreciate not riding through the spray normally thrown up by the rider ahead.

Your bike will thank you and your winter clothing will last longer. Commuters will find mudguards essential, and mountain bikers will find it easier to keep warm and dry through the most extreme conditions.

What size mudguards do I need?

The wheel size and width of the tyres fitted to your bike determines the size of mudguards needed. For example, a wheel that is 700c with a tyre of 32mm width will need a mudguard made to accommodate those measurements.

How do I choose mudguards?

There are many different types of mudguard. If your bike has eyelets near the front and rear dropouts, along with attachment points in the fork crown and seat stays then full-length mudguards could be fitted. For bikes without these attachment points, there are other clip-on options.

How do I install mudguard?

Full-length mudguards have stays that attach to the eyelets on the front and rear dropouts. The front will also attach at the fork bridge. The rear will also mount at the seat stays and often behind the bottom bracket in the centre of the chainstays.

What are mudguard eyelets?

Mudguard eyelets are small threaded holes near the front and rear dropouts. These allow a bolt to be used to attach the stays of the mudguard.

Can you put mudguards on a road bike?

A traditional road bike with rim brakes and narrow tyres (around 25mm) will often not have the clearance or mounting points needed for full-length mudguards. There are various clip-on options available for road race bikes.

How much do mudguards slow you down?

When the mudguards are fitted correctly they should not rub on the tyres at all. This means that they will not create any friction against the tyre and will not slow you down in any way.
