JoeBlow Gets Fat Over Winter, New Floor Plump Dials in PSI Under 30

Toepeak Joe Blow Fat pump (2)

Judging by all the fat bike specific product popping up, you might think you would need all new everything to get your fat bike fix. While not totally true, there are a few things that would definitely make life easier – like pumps that are more accurate at low pressures. We caught wind of the new Topeak JoeBlow Fat at Eurobike, but it seems the company has made a critical change to the pump since we laid eyes on the prototype. Instead of making the pump just for fat bikers, why not build a low pressure pump that will fit the needs of most mountain bikers and cyclocrossers while they’re at it?

Thanks to a small tweak, anyone running pressures under 30 PSI should be a fan of the new JoeBlow family member…

Originally, the prototype JoeBlow Fat had a gauge that topped out at just 15 psi. While that would provide excellent readout to really dial in those low pressures, it excluded just about everyone but fat bikers from the new pump. By bumping up the maximum PSI to 30, the Fat should still provide plenty of accuracy at the lower ranges but it opens up the pump to use for most mountain bikers and cyclocross riders who are running low pressures and looking for more accuracy at the pump.

According to Topeak, the pump is built so that one stroke of the massive barrel equals one PSI. Combine that with a gauge that is supposedly accurate to +/- 1 PSI and you should have an awesome low pressure pump.

Equipped with a dual sided TwinHead, the JoeBlow Fat adds a bleeder valve right at the tee for easy adjustment of pressure. Riders looking for more than 30 PSI but still lower than road pressures may also want to check out the JoeBlow Mountain which tops out at 70 PSI. Available in about 3 weeks, the JoeBlow Fat will sell for $54.95.

If only the gauge on the JoeBlow pumps could be accurate … 2bars on mine is 2.55bar … it’s like a 25% accuracy O_o

I recently checked the accuracy of my floor pump gauges. Using 2 different digital gauges which were within 1 psi of each other I found that the JoeBlow Pro was 8psi lower than the gauge read at road pressure and 6psi lower at mtb pressure. 6 on 30 is nothing to sneeze at..

not a fan a joe blow chucks, or just in general. might replace my venerable airtool comp if specialized comes out with a “high accuracy at low pressure” pump, though.

*sigh* accuracy? Maybe you should be more concerned about repeatability?

If I needed pump this would be at the top of the list, but the last Topeak I bought just won’t die….that was about 15 years ago.

I may be missing something, but wouldn’t psi per pump stroke also be dependent on volume? If that’s the case, do they specify what tire range will obtain the 1:1 ratio?

There are a lot of pumps, but I think my Topeak pump is 18 years old or close to that. Quality control.

My Nashbar pump is 20 years old and still going strong. It was cheap, but works great with road and mtb tires. Pumps are pretty simple devices that last for a long time. It’s a cheap investment.

@enduro_bro well what’s the point of repeatability if the base value is completely wrong ? Up to the point where I bought a digital gauge, I just couldn’t have any precise pressure … And no, the “thumb test” on the tyre doesn’t work accros a wide range of tyres.

Now I know that I have to pump the front to 1.3-1.35bar and rear to 1.4-1.45 … for a 1.7-1.9bar range of effective pressure.

Sometimes, a missed typo is appropriate – FLOOR PLUMP! Ha!

I’d prefer a little higher as the max – like 45 so cross, gravel, mtn are all covered.

My experience w/ this company has been very good w/ their sport model; had QC issues with an older Silca and a few other brands. It’s the only one that lasted more than 3 years.

Silca died within a year but I understand they have new ownership so that’s perhaps changed things.
