We’re perfectionists: if it’s not good enough to fit to one of our Brommies, we don’t sell it.

Available for both fixed and spider chainrings – they fit all Bromptons ever made. Will never fall off or snap! No more oil stained trousers… a simple replacement for a missing Brompton chain guard.

Coloured Metal Replacement Mudguards and Fenders.


Rolled by hand from aluminium. To reserve a set of mudguards in a colour not listed email us and we’ll make you a set.

We offer both rack-type and standard replacement alloy coloured mudguard / fender blades, with stainless or carbon fixing options. If your bike already has Brompton mudguards, simply retrofit the blades (they work perfectly with the existing Brompton fixings currently holding on your brittle plastic mudguards). To take your naked E type Brompton without mudguards all the way to an R type with rack and mudguards or an L with the mudguards and rear roller. Add new Brompton stainless mounting stays, or go for superlight titanium.

Brommiemods mudguards are designed to work perfectly with the larger tyres fitted to some Bromptons (the Schwalbe One or Continental Urban). Made in aluminium alloy for strength and powder coated to match your frame (or go for a contrasting colour for a unique look).
