There are several models of Topeak Joe Blow floor pumps. Are they much different? How? For example between Topeak Joe Blow Sport II Floor Pump and Topeak Joe Blow Max Hp Floor Pump? Thanks.
I'm not sure of the difference between those pumps but I have a Joe Blow sport II and it works.
I keep the Joe Blow at work. I have a Specialized air tool at home.
Looks like the Sport II is a little taller (more volume/stroke) and has a metal base/stand. So a few upgrades. I have the original Sport model and it's a good pump. I like the JB pump head, it's better than most in the price range.
With my old eyes it's nice to have the gauge at the top rather than at the bottom.
Thanks. The Sports II's gauge is black background, the Max HP has a yellow background gauge, which seems to me more easy to read. The Sports II may be heavier with the metal base, so for $10 less the HP has more appeal to me :).
I had a hard time with the way the lock worked and it's the same on both of those pumps. I now have the Pro which has a different locking mechanism.
The Mountain pump is a whole other beast! I have 2" wide tires that I put 40 or 45 psi into. That's what the Mountain pump is for. The gauge maxes at 70 psi or so. The 30-50 range is easy to read. The diameter of the pump is bigger than the higher pressure pumps. That helps to fill these high volume tires more quickly. But it also means that you have to push harder for the same psi - the barrel has more square inches of cross section, so you have to supply more pounds to get the same psi. I never run it up to 70 psi but already at 50 psi you have to push pretty good. Not that I am Mr. Muscle by any means. But I do have a bit of weight to put into it!
Yeah. MTB pump = greater volume/stroke and better resolution gauge appropriate for the lower pressures. I typically run between 25 and 35 psi depending on conditions.
I have a Topeak Sprint road pump among a few other brand pumps. I don't know if that's a current model. Works fine and the "TwinHead" chuck works well, which is often the differentiator between pumps. I've never used the schrader side. I recently got a rebuild kit for the head as the presta gasket was getting loose from wear.
I had a Joe Blow for a long time, it was good, no complaints. Just replaced it last year with the Nashbar "Big Orange pump." I really like the Nashbar pump, couldn't be happier with it. I know this doesn't address your question specifically, but sounds like you're shopping so thought I would offer a recommendation.
I have a Joe Blow Max HP and really like it a lot.
