Best Bike Mudguards and Fenders for Wet-Weather Triathlon Training 2026
What to Look For
A good chunk of the UK training year happens on wet roads, and mudguards keep road spray off you — and off anyone riding behind you, which is why many club chaingangs and turbo-to-outdoor group rides require them. Most race and tri-position road bikes don’t have mudguard eyelets, so the choice usually comes down to a clip-on set you can remove for racing, or full-length eyelet-mounted guards on a dedicated winter bike.
Key Features to Consider
- Clip-on vs eyelet-mounted — clip-on guards fit almost any frame without mounting points; eyelet-mounted guards offer better coverage but need a compatible frame and fork.
- Coverage — full-length guards with a mudflap keep noticeably more spray off than a minimalist rear-only guard.
- Tyre clearance — guards are sized to a maximum tyre width, so check your own tyres fit before ordering.
- Weight and removability — if you’re swapping the same bike between training and racing, look for guards that come off in minutes without tools.
Our Top Picks
Best Value: RRP ProGuard Rear Mudguard
A simple, clip-on rear-only guard at £22.99. It won’t keep you as dry as a full set, but it stops the worst of the spray you’d otherwise send onto anyone riding behind you, for not much money.
Best Overall: SKS Raceblade Pro Mudguard Set
A full front-and-rear clip-on set at £37.99, designed specifically for bikes without mudguard eyelets. This is the go-to option for triathletes and road racers who train on their race bike through winter and don’t want a dedicated second bike.
Best Premium: SKS Chromoplastic Full Length Mudguards
Eyelet-mounted full-length guards at £43.99, for maximum spray protection if you’ve got a winter or turbo-commuting bike with proper mounting points. The gold standard for staying dry on genuinely filthy rides.
Buying Tips
- Measure your tyre width and frame clearance before ordering — guards are sized to a maximum tyre width and won’t fit if you’re close to the limit.
- Remove clip-on guards before racing. Most triathlons don’t require them and they add unnecessary drag and weight.
- Fit guards before the first wet ride of the season, not after — a five-minute job in the garage beats doing it in the rain.
Care and Maintenance
Wipe guards down after muddy rides to stop grit wearing through the stays, check clips and mounting points for cracks each season, and replace mudflaps once they split or curl — a cracked flap sends spray straight up your own back.
