Types of Bike Mudguards — How to Match Them to Your Bike
Mudguards are one of those parts you appreciate immediately after your first ride in the rain without them. A wet stripe up your back and a muddy face can ruin even the best ride. The question is: which mudguards suit your bike?
Full (permanent) mudguards
Bolted permanently to the frame — they wrap around almost the whole circumference of the wheel. They give the best protection against mud and water. The standard on city, trekking and touring bikes.
They need mounting eyelets (holes) in the frame and fork. If your bike doesn't have them, you can't fit full mudguards without adapters.
Materials
- Plastic (polycarbonate) — light, cheap, corrosion-resistant. The most popular choice.
- Metal (aluminium) — more durable, stiffer, expensive models look elegant.
Clip-on mudguards
Fitted without tools — clipped onto the seat rail or the wheel axle. Quick to fit and remove, but the protection is partial — they only cover the top of the wheel. Good for a road bike in case of rain.
Seatpost mudguards (ass saver)
A minimalist strip of plastic slid under the saddle. Protects your back and backside, but not your legs or the drivetrain. Zero extra weight, no tools needed. Ideal as an emergency option to keep in a backpack.
Mountain bike (MTB) mudguards
Short, mounted on the fork or under the saddle. On MTB, full mudguards don't make sense — they collect mud and branches. A short fork-mounted mudguard protects your face from water and mud thrown up by the front wheel.
How to choose the size?
- Width — the mudguard should be 10–15 mm wider than the tyre.
- Wheel size — check the marking: 700c (road/trekking), 26"/27.5"/29" (MTB).
- Clearance — make sure the mudguard doesn't rub against the tyre, especially with V-brakes.
Fitting — what to watch out for
When fitting full mudguards, make sure the gap to the tyre is even all the way round. The stays must be tightened properly — a loose stay can get caught in the spokes while riding. After fitting, turn the handlebar through a full circle — the mudguard shouldn't catch on the frame.
