Australian company JetBlack’s RX Road has a similar design to the Lezyne Road Drive Mini, but at 32cm in length it’s more compact and lighter too, weighing just 114g.
It has a highly impressive pumping action and feels very good to use, with a 15mm diameter shaft and a reversible screw-on chuck that creates an ultra-secure connection with the valve. The action does start to become harder work after about 125 strokes, but even that would probably be enough to get you home – and we reckon you could hit the claimed 140psi maximum if you were prepared to put in the effort. It doesn’t get as hot as some either.
It’s not super-mini, but it is light – and Jet Black is confident enough to give it a very welcome lifetime guarantee. The plastic mount has two rubber O-rings, so it should be secure on the bike.
