BRAE Cycling Mudflaps

Rear Mudguard Flaps for Cyclists — Made in the UK

Nobody wants to be the rider who soaks their mates. Brae Cycling's mudguard flaps attach to your rear mudguard and extend its length, stopping spray and road muck from hitting the riders behind you — essential kit for group rides and commuting in British weather.

Designed in partnership with RAW Mudflaps UK and made from durable polypropylene, our mudflaps are built to last through season after season of wet riding. Available in two widths to fit standard (35–45mm) and wide (45–55mm) mudguards, with all fittings and instructions included.

  • Extends rear mudguard for superior spray protection
  • Available in standard (35–45mm) and wide (45–55mm) sizes
  • Durable polypropylene — made in the UK
  • 2-bolt attachment with all fittings included

Stop the Spray — Ride Considerately in Any Weather

At Brae Cycling, we believe good kit makes you a better riding companion. Our rear mudguard flaps are a simple, effective upgrade that keeps the riders behind you dry and clean — whether you're on a winter club run, a commute, or a loaded touring ride in the rain.

Designed in partnership with RAW Mudflaps UK and manufactured in Britain, each flap attaches to your existing rear mudguard using a 2-bolt system. All fittings and instructions are included, so installation is straightforward — though it does require drilling at least one hole in your mudguard.

FAQs

Which size mudguard flap do I need?

Measure the width of your rear mudguard. If it's between 35mm and 45mm, choose the Standard flap. If it's between 45mm and 55mm, choose the Wide version.

Do I need to drill my mudguard to fit the flap?

Yes — installation requires drilling at least one hole in your rear mudguard. Full instructions and all fittings are included in the box.

Are the mudflaps suitable for year-round use?

Absolutely. While they're especially useful in winter, the durable polypropylene construction means they'll handle wet and muddy conditions in any season without degrading.

Can I use these on a touring or commuting bike?

Yes — they're ideal for any bike fitted with a rear mudguard, including commuters, tourers, and winter training bikes.

Fork bags

Very good quality, easy to mount, kept everything dry

Brilliant bag.

I’ve been looking for a bag that would fit my Brompton G Line rack, and the Wynd Bag is absolutely perfect.

It fits the rack brilliantly and can be removed in seconds, so you can simply throw it over your shoulder before folding the bike at the train station. It’s just as easy when you arrive and unfold the bike.

The bag itself is excellent quality and feels really well made. It’s exactly what I was looking for and makes using the G Line with the train so much easier. Highly recommended!

Amazing Bags

I was after small waterproof luggage options to spread the weight of my gear on my motorcycle. These are perfect and work really well on motorcycles to attach to editing luggage or frames.

Exceptionnel Service

I purchased a bar bag 13 months ago, unfortunately the zip broke. This was replaced without question (all I did was send a photo) within 3 working days. I judge a company by how it reacts when things are not perfect These guys are great.
