Good quality but let down by fiddly dual valve design
on 10 October 2014
The Airace Infinity is well-made metal barrelled floor pump with easy to read gauge up to 160psi, pressure release valve for deflation, sturdy feet and comfortable handles. The flex is a good length, allowing connection to the valve even when at the top of the wheel, and the head will fit both Schrader (wide) and presta (narrow) valves.
It is the dual purpose head however which lets the pump down, for although it is claimed to be `clever' by detecting the type of valve it is being pushed onto, it is actually just a tapered fitting which fits both styles of valve once the locking lever is turned.
There is a knack to getting the head securely onto the valve, but considering the many alternatives on the market I find it disappointing to have to overcome this fiddly design which is labelled as clever.
For Schrader valves I found no problems. The head pushes onto the valve tightly and the lever is turned to lock it on. The tyre is inflated with no problems.
Presta valves I found difficult to fit. Valves with a thread and locking nut are easier for the head to lock on to. The thread gives the head some grip, while the locking nut stops the valve being pushed into the wheel innertube when locking down the head. Presta valves without a thread or locking nut are smooth and as such are difficult for the head to grip, and tend to get pushed into the wheel when the head is pushed on.
The knack is to hold the valve tightly and push the head firmly down onto it, quite hard so that it grips as much valve as possible but not so hard as to cause damage. With practice it can be achieved every time, but despite following this method I still occasionally find the head pops off the valve midway through inflating the tyre.
A dual head design would be more reliable - adapters are available at low cost - and it's a shame this pump wasn't fitted with one.
