Topeak Joe Blow Booster Floor Pump w/SmartHead DX3 (TJB-BST3), Black, 29.1” X 9.8” X 7.3” (62002365AFFP)

Although I returned this pump, it is a 5 star pump based on other user-reviewers (that's why I purchased it). I returned it because the pump will not work with the valve core removed. I prefer to remove the valve core to seat the tire on my carbon rims. And, I prefer to inject sealant through the valveless core AFTER the tire is fully seated . . . absolutely no sealant leaks. I've made too many messes (my own inexperience and carelessness) by pouring the sealant into an unseated tire. You can mount tubeless tires without removing the valve core, and that's the only way this pump works.

Pump is low volume high pressure so larger tires take longer to inflate (not a big deal on bike tires). Inflator mode is lower volume than expected but has worked on plus tires, could see this not being as effective for fat tire bikes, but long hose and tank make it easier to manipulate the tire while setting bead. Overall works great!

I was on the fence between a compressor and this pump to do my tubeless conversion. I ended up using this because most of the trail we want to ride are road trip distance away. Using this pump I did my first ever tubeless conversion of 27+ and 29+ tires for our bikepacking bikes. The 27+ tires were tougher and required a few tries and squeezing the tire so it was closer to the rim edge. But for my first time I would say 4 for 4 is a good testament for this pump. Can't say it will work for all tire/rim combos but it worked great on our Surlys. Highly recommend.

I used these types of pumps before. My previous model worked correctly, but this one would not hold air and couldn't even be used as a regular pump let alone a booster pump for tubeless tires. I returned it and didn't bother getting a replacement.

I worked in shops as a bike mechanic for years and seated countless tires on the job. I thought this would be a nice alternative to an air compressor since I am now in a different line of work and do not have a compressor at home.After working on my own bike, I can say that this pump simply will not seat some rim/tire combos. Basically, if a regular floor pump would seat the tire, this one will do it a little faster. If a regular floor pump wouldn't do it, this one won't either. You'll still need a compressor.Now I'm outside the return window and stuck with a big, heavy, and incredibly expensive floor pump, and I still have to drive to an LBS or gas station to seat my tires.In the words of Rick James, "four thumbs down."

perfect for tubeless set up!

works great

I love this pump. This one was a gift for my niece, who is a new road rider.

Product does what it is supposed to do. Nice solid product. Easy to pump. And cool features. Some extra info would be great though on conversion from pump types. As I had to guess. And have an extra little rubber seal that I think was supposed to be taken off for pumping up my tire for my fat bike. It worked in the end. But no instructions. Just guessed. Apart from that. Worth it.
