TopeakJoeBlow Booster Floor Pump w/SmartHead DX3(Return to Product Page)

I have a couple of things to share after using this pump 3-4 times a week for almost a year. The biggest learning I had was to pump a tire to pressure and then close the tank/chamber valve before disconnecting the pump head from the valve stem. The disconnect and sealing of the Presta valve is fairly instantaneous instead of leaking off. Plus, there is less pumping to get to pressure for the next tire. Topeak should add this to user instructions for less savvy people like me. I have left the reserve chamber at pressure for multiple days without significant leakage and dropping in pressure. Its pressure gauge is easy to read and its accuracy matches my Topeak expensive digital pressure gauge. The pump head also fits Shrader valves nicely and without having to disassemble and reassemble the pump head like some other pump heads. The build quality is excellent. I can't think of anything I would change on it. I hope it lasts as long as the 25 year old and still going Avenir pump I gave to my son.

Just what I needed to support my tubeless requirements for my bike collection.

5 stars on overall rating; 4 stars on value rating at list price (5 stars with 25% BTD discount). Pump is built like a tank and is very solid standing up. This is helpful to keep it from being inadvertently knocked over and possibly damaging the very readable and accurate pressure gauge. The SmartHead works very well on both Presta and Schraeder. The lever securely locks the head to the stem with ease. The extra-long hose is nice, but I have not found it necessary for my use. Switching from the booster cylinder to regular cylinder is straight forward. It has worked well to reinflate my Conti 5000 S TR tires after refreshing the sealant. I have them on Zipp Firecrest 303 wheels, which are an easy-mount combo. I initially mounted them with a standard floor pump with more effort than it takes with this pump. This is a heavy floor pump and less suitable for frequent travel with than a standard one. It would be nice if Topeak would provide a chart to recommend how much pressure to store in the booster cylinder to safely and efficiently mount various tire sizes. The user has to figure this out by trial and error. A concern is that these Zipp wheels have a manufacturer's maximum air pressure rating of 72 PSI.

I have 2 bikes with tubeless tires and sometimes its hard to get the tire inflated properly and to get the bead to seat. This sure makes it easier!

The integrated chamber is a lifesaver if you run tubeless. I tried just pumping fast with a regular pump, just to see if I could seat my tire and there's just no way. It was pretty much a snap with this pump. I also just plain favor it over my other pumps for every day use. Expensive, but well worth it to me.

This pump makes seating tubeless tires very easy on road bikes. It was impossible without it. I was able to seat 4 tires very quickly and single attempts.

However, the pump doesn't seem to form a great seal with presta valve. When using it to fill air it seems to leak air at the nozzle.

I was using C02 cartridges to seat tubeless tires which is wasteful. This pump is a much better alternative.
