This pump was first seen with the Brompton x Barbour bike which was a new 2022 model Brompton folding bike
It's a frame-mounted Brompton Pump, like the black one but in silver.
Big power, mini size for faster, easier roadside repairs on all Brompton models.
The pump itself weighs less than 100 grams and inflates up to 160 psi.
It is made in collaboration with the experts at Lezyne.
Brompton say "The new Brompton pump is by far the best pump we have made. Now Schrader and Presta compatible, and with the Lezyne ABS Flex Hose you can also access hard-to-reach valves (including Brompton Electric). The overlapping handle design makes inflating easier than before with a longer, more efficient pump stroke. The sleek CNC Machined Aluminium body designed with both weight and style in mind mounts to the Brompton rear frame (mount included) - ready to grab and go whenever it’s needed."
