The pump certainly feels reasonably solid, weighing 166g, which is pretty chunky considering it’s just 23cm long. This is down to its largely metal construction. It has rubberised grips at both ends, but unlike most pumps without a hose, the BTwin doesn’t have a locking lever – you just push the head firmly onto the valve.
But would it hold? It’s very loud as you pump, with the handle end clipping against the barrel, but the action is good and light – and yes, the chuck does stay on.
The pressure after 200 strokes isn’t that high, but the connection was all right and we reckon you’d get to around 100psi in around 400 strokes. It comes with a standard mounting bracket, though without O-rings or any Velcro, and we’d be tempted to add a strap when it’s on the bike.
