How To Use Joe Blow Sport Pump
The Topeak Joe Accident Sport Digital carries a venerable pump name into the digital age, calculation a triple-readout gauge to the iconic design. Whether this is a benefit or a drawback will exist in the eye of the beholder, every bit there are display delays, and the hose isn't too long either.
The Joe Blow is a legend of a pump – for at least xx years the blackness and yellowish steel barrels take powered endless cycling adventures. Recently Tony reviewed the Joe Accident III Sport, finding that for £40 it was a nearly-perfect purchase. The Sport Digital adds a digital estimate – everything else is identical to the Sport Iii.

The Joe Blow range has no fewer than 22 models in the lineup, the £40 (often cheaper) Sport III being pretty much the lowest offering. At £seventy the Sport Digital is quite a premium for digits instead of a needle.
Roofing the fundamentals, it'due south a steel-bodied, steel-based pump with a 75cm pivoting hose that'south skilful for valves upwards to about a metre off the footing – and then somewhat limiting for bikes at eye top in a workstand, or on a wall or car rack. The T-head connects to Presta, Schrader and Dunlop valves, with a strong thumb-switch that actually needs two easily to actuate if you don't want to risk breaking a fragile Presta head. The whole caput associates is available every bit a spare part for about £ix. The head or hose doesn't feature a bleed valve, and then y'all're only going up, not downwards.
As Tony found, the handle is pretty skilful. Information technology's nicely curved, with a dual compound that's pretty grippy if it's wet, or hot and your easily are slippery.
In terms of inflation, the smooth activity of the steel bedroom helps get tyres upwards pretty speedily – a 29er 2.2in tyre got to 25psi in 30 strokes, and a one.2L Birzman Tubeless tank to 150psi with merely 50 strokes; 28mm and other similar sizes were likewise quick to inflate.
The Sport Digital maxes out at 160psi, and indeed pumping gets pretty hard around that indicate. These days, pressures like that are only going to be for tubeless tanks, and if you actually want to get higher yous tin can – simply exist prepared for a fight.

The gauge displays in psi, bar and kg/cm2, and also shows battery level which is handy for knowing when to buy another two CR2032 push cells (the specifications say i battery, but trust me, it takes ii). Once you become over 100psi, the guess drops the decimal place. Accuracy is claimed at +/-1psi below 100, or +/-1% above 100. Compared with other pumps and a digital SKS Airchecker approximate, the Sport Digital was bang on.
Actually, the but downside to the Sport Digital is the major selling point – the digital approximate itself. When you're pumping, information technology only loosely indicates the range yous are in. For case, when pumping at around 30psi, the estimate could be bouncing between 25 and 50, and volition only settle downwardly after peradventure 2 seconds. Then later on iii seconds information technology drops dorsum half a psi, every time.
This filibuster might not sound like much, merely compared to an analogue gauge where your brain can keep track pretty well by averaging out where the needle is pointing, with a digital gauge this is impossible. So you stop upward stopping a few times to check, instead of heading directly to shut-enough as with a needle gauge.
Maybe Topeak could come up upwards with a less sensitive, averaging guess. Once you understand that every stroke is pretty much bang on 3psi, things become a chip easier to aim for, just for £70 yous'd expect an immediately more than accurate result that didn't require stopping to average out and display.

The toll of the Sport Digital is in line with other digital flooring pumps, such as the Lezyne Sport Digital Floor Drive. However the Lezyne Macro Flooring Drive Digital paints a better value picture – with a longer hose and 220psi capacity for £20 less, it'southward a practiced alternative.
I feel Topeak could practice better here. With a longer hose and a more stable judge, the Sport Digital would be a better, more usable pump. The fundamentals of build quality and spare parts are in Topeak'southward favour here, and if you aren't fussed by an immediately-visible pressure or a not-too-long hose then the Joe Accident Digital Sport is a adept pump.
Verdict
It'south a solid pump, let downward by a jumpy display and curt hose
