Topeak JoeBlow Booster Bike Pump

I needed a pump for my tubless and this was recommended to me by two people. It's expensive but when you get it you feel you got your money's worth as soon as you open the box. Feels sturdy and did the job for repairing my flat tubless tire on my mountain bike. All parts used feel like they will hold up to the test of time but only time will tell. I'm happy with my purchase and I would recommend this pump to others that need a two in one tubless tire pump

I have another Joe Blow that is 8-10 years old and it still works flawlessly.This JB is heavy duty and is no lightweight. Best features are the high mounted gauge and best in class chuck. It’s the best chuck I have ever used. The primary pump works perfectly and I have used it on both Schrader and Presta valves. Frankly, it’s overkill if you are only using it to pump tires unless you have a LOT of tires.I have had mixed results with the second chamber for seating tubeless beads. I had no trouble seating the tubeless tires that came with the bike, but the very supple replacements just wouldn’t seat. Pumping 40-50 times to fill the fast discharge chamber gets old when you do it four or five times without success. A work around might have been inflating them with inner tubes firs to help them conform to the rims. A compressed air gun made quick work of it at my LBS.If it holds up as well as the first pump it will justify the high price.

I had an air good floor pump. I purchased this because I was going tubeless. Appearance is very sturdy and demanding. It has the charging port made for tubeless and it works ok. Is it worthy of the money? The jury is still out. When using the charge for inflation, I expected it to pump the air and then have released all air from the charge into the tire. However, it has air stilll in the line, which means you then have to pump more air in the tire to have the desired pressure. What? Yes, if I charge for 80psi and turn the dial to deliver 80psi, it may only deliver 60, and I have to pump more air to reach 80psi. Not efficient, in my opinion.

Was having alot of trouble setting the tubeless tire of my mountain bike. Didnt want to buy an expensive electrical air compressor. This one worked easily! Only thing I was unsure on what that I had to increase to maximum pressure of 160 PSI before letting it rip. No issues

I got this after returning the Lezyne Digital Pressure Overdrive that has a similar canister feature for tubeless. The Lezyne seemed well made, but the controls, gauge and chuck were a pain to use even when you know how.I compared that to a this Topealk model that a friend owns. The controls are much better. The chuck is quick to engage unlike the Lezyne screw on chuck. The Topeak just works better and with no odd quirks, so I bought one and am quite happy with it.I also like that it’s easy to replace parts on the Topeak so I don’t have to buy a new one if the hose or some other small part goes bad.

It could just be the returned item I bought, but a fully pressurized chamber release felt like more of a slow leak. The air escaped from the wheel faster than the pump could deliver. I'd specifically selected this pump to help seat tubeless road tires but returned it as unusable. The pump itself was decent when used as a normal pump.

Less money and space than an air compressor option.

It was a resale and it was in perfect condition. Only the box was damaged
