Brompton Borough Waterproof Pouch - Navy / Grey
New for 2024 and introduced along with the G Line (20 inch wheel Brompton folding bike) range
This pouch is almost the same as the existing black waterproof pouch - which we even trust for carrying our camera in the wet (it has a roll top to help keep the water out)
It has a G logo on the front - which is removable (held on with velcro) and can be replaced with a Brompton logo (also included) for those not riding a G Line!
Compatibility
This pouch is compatible with all models of Brompton folding bikes
The Brompton Borough waterproof roll top pouch (that is a bit of a mouthful) is designed to be attached to your handlebars or saddle loops (if your saddle has them) or saddle rails using a pair of simple velcro straps.
A third velcro strap attaches to the seat post or handlebar stem to stop side-to-side movement
It's ideal for carrying your essentials when you want to travel light, or for extra capacity on inclement adventures
