Topeak JoeBlow Booster Tubeless Tire Floor Pump – Dual Function Air Compressor & Standard Pump, 160 PSI Capacity, SmartHead DX3, Black

Extremely good. Great Quality and easy to use. This pump is what I need to inflate my tubeless tires.

This pump does what it says it does and does it well. Extended effort pumping up fat tires - which it was not designed for - is livable thanks to its design and ergonomics (200 strokes in, pump ergonomics is a lot more meaningful than when you were at Stroke 25). Also the tubeless charging feature is useful on tubed tires as well as tubeless, especially if you are trying to seat the bead on an odd tire and rim combination. If you have a range of tires going from fat 26" to skinny 700c, tubed and tubeless, this can be your one pump to rule them all.

This is easily one of my favorite purchases this year, and I've bought quite a lot of mtb things! It feels pretty bullet proof with metal canisters, and I was able to seat up every bead on every tubeless wheel setup so far with perfect execution since I got it.I love this thing!

Received yesterday and have used the pump once but not the booster. The build quality on this seems very high. All parts seem to be thick and either thick aluminum or heavy plastic. I'm quite impressed with the general quality of the entire assembly. It appears to be a premium part as it should be at this price.The hose is quite long (much longer than my other pump) and has niceties such as hooks to keep it arranged. The base plate is sturdy and seems sufficiently big to not have any stability problems. The hose head attached easily and the action was smooth and with ease. I don't think connecting/disconnecting lost any pressure but I would have to verify again. The head is large and I doubt would work for a shock pump.Topeak seems to sell their devices with longevity in mind and accordingly has a large array of replacement parts listed on their site though I'm not sure if they apply to all products. It isn't clear if they have a rebuild kit for this pump or not but they do advertise replacements for a couple of the parts.Note: This maintainability is actually a problem for a bike mechanic I know who wears out shock pumps frequently and has to replace the whole pump rather than the one o-ring which went bad. This typical manufacturer mentality is disappointing.The gauge is a bit disappointing. My old pump gauge "sticks" and doesn't smoothly change with pressure. The smoothness of this gauge is definitely better than my other which I appreciate but the lack of finer graduations is disappointing. Tubeless users might want to distinguish between 18 and 19 PSI pressures depending on their terrain. Maybe even lower with super fat tires but I'm not as familiar with those. The gauge doesn't play well with those situations which is a pretty unfortunate for such a high quality part.I really want to like this pump and while I think I can live without the graduations, my other pump has them and I will prefer it because of them. Therefore, this pump will either remain lightly used or I will return it. This is disappointing for such a nice pump.To fix it, I would either make the gauge bigger, add a digital read to the analog, or switch to digital. I think the first two options are the best options and don't think I'd prefer a digital pump. Adding an upgrade option would be nice too because they offer so many parts and it might just be replaceable.Overall:Build quality: 5/5Usability: 3/5Usability without gauge: 5/514 months after purchase update:The compression chamber has always worked for me and it makes tubeless setting simple. Too those who have problems with it, they may have a tricky wheel/tire combo. This works well for tires which seat easily. Perhaps a shorter or thicker hose would help by increasing the flow rate. Or some flow rate adjustment somehow.I've grown accustomed to the gauge precision and don't mind the graduations though it bothered me at the beginning. Topeak announced a digital gauge version which would fix the precision problem.The aluminum base plate is small and inflexible which means it really needs to be sitting on flat smooth ground. This pump is very solid and rigid feeling which contributed to this needing a flat surface. I wish the plate was bigger giving more room to stand on the gauge. I also wish it had something to make it work better on terrain which isn't perfect, whether a gasket on the ground or a little plastic. It would be nice.The valve head doesn't work at all on Schrader valves. The site claims it does but mine doesn't. I have to use a presta adapter to pump with it. Schrader isn't difficult. Add a screw but it doesn't have one.I find the pump gives plenty of air per stroke but I don't have super high volume tires either. I also think the force required for pumping is reasonable. If the pump output was higher volume as some have requested, I don't think my mom could use it because the force would be higher. So I find it is a good trade-off.Overall, I consider it a high quality pump which could use a wider foot plate which works on uneven terrain and needs an improved Schrader valve attachment. Perhaps a way to adjust flow rate because some find the flow rate too low.Overall rating: 4/5Reliability: 5/5Usability: 3/5 (Schrader big problem)

An excellent addition to my bike maintenance shop equipment. Functions as described and is very effective in seating your tubeless tires on your rims. It's easy as filling the reservoir and then using that stored pressure to inflate the tire and seat it on the rim. It's very effective for everyday use, but is specifically designed with the tubeless application in mind. It is well designed with strong components that should last for years. I recommend it to anyone who wants this type of functionality while being able to cover the everyday tire inflation use, as well!

A full-on compressor is your best bet to pop your tubeless tires into the rim, but this did the job, and it's a nice pump. It doesn't feel quite as sturdy as my old Specialized one (which cost as much and doesn't have the external chamber), but it's not cheap feeling, either.

This pump does what it claims - seating a tubeless tire onto a rim on the first try. No need to use an air compressor to seat a tire, just get this. And it's cheaper than a decent air compressor.

Works just as well as a compressor for seating tubeless tires. Even if you're not tubeless yet, it's almost worth it for the extra-long hose (keep the pump on the floor while the bike is on a workstand, without having to fiddle around) and the quick inflation feature (charge the reservoir to a little above the pressure you want, hook up the nozzle, twist the dial to "Inflate", watch the pressures equalize, and cut it off exactly where you want). The dial is easy to operate with one hand and everything about the pump is user-friendly and durable.
