The Birzman Velocity has everything you could need in a pump in a pocketable package
The Birzman Velocity with gauge mini pump has a solid feel, with an aluminium barrel and head, and grippy rubber at both ends to hold onto when pumping. The hose extends from the top of the head and includes an in-line pressure gauge calibrated up to 150psi.
The press-on Snap-It valve connector proved really easy to use. It has an outer sleeve which is pulled back before pushing the adaptor onto the valve. Once on the valve, the sleeve is pushed back up to seal the adaptor. This proved really easy to use both to attach and detach the pump from the valve. The Snap-It head can be unscrewed from the tube to reveal a schrader valve adaptor.
Although slightly less efficient than other pumps we have used recently, achieving just over 90psi after 200 strokes, it was much more comfortable to use, thanks to the longer stroke and rubberised grip.
The cap covering the hose did not seat very well. It would be unlikely to get lost, however, as it is very firmly attached to the pump itself.
As one of the longer pumps in the test, the Birzman extends out of a rear pocket, but it happily survived the Rapha Hell of the North ride without budging. There’s a plastic clip with a sturdy rubber fastening for mounting to the frame.
An easy to use, efficient pump with clever features
