Works like a champ!
I have an older model of this pump (8 or 9 years old) and it is still going strong! I use the pump several times a week, almost every week of the year – most of the time on my road bike, but occasionally on my mountain bike. I use it exclusively on presta valves (often on long-stem presta valves) and have never had a problem. The one time I used it on a Schrader valve was to put air in a car tire, and it worked!
I can only wonder if the reviewers who have had a problem pumping up tubes with presta valves are doing something wrong. The pump has always worked perfectly for me.
Note that for deep rimmed wheels, if you are using a screw-on valve-extender, those can twist off slightly when you clamp the pump head on, and thus release air while you are pumping, so that can be the issue rather than the pump. Also, the wrench flats on the extender can preclude a good seal.
Great pump, reasonable price
This pump seals easily and completely and doesn't release a ton of air out of my tire if I'm klutzy when putting it on the nozzle. It pumps without requiring superman strength. It doesn't hit the same place on my hands as my bike handlebars, which is usually sore for me. The pump hose pulls over and stashes across the handle, so you can grab the handle to move the pump without the handle rising. It has a place right on the pump to store the attachments (for pumping floats or balls). Love the yellow color. I have had more expensive pumps, and this one works just as well or better than those. My other pumps have not lasted a long time so hopefully this one will have more longevity. The previous pumps I have had that were not very expensive did not have replaceable parts, but the REI salesperson said I can replace the nozzle on this one if it wears out, so hopefully that will be an easy process if it becomes necessary.
Excellent Easy to Use Pump
I use this pump almost daily and am always impressed in how easy it is to use on both my presta and schroeder valves. I also really love the hinge-to-lock design. It creates a great seal every time and is also easy to remove from the valve. This also came with several other attachments for inflating balls and such. I have not used these but am sure they will work great. The dial is not easy to read from a far distance, but does have a movable guide (pointer) that you can set to your desired pressure. You can then easily tell where the pressure is in relation to that point. It also has removable and replaceable parts so if something breaks, it doesn't necessarily mean you have to buy a whole new pump. I am sure I will have and use this pump for years to come. Overall, I am extremely happy with this pump and would definitely recommend it to anyone with a bike!
This may help some folks.
I just bought this pump, but just a 2nd one to leave in my car. Others have said that this pump doesn't do well on presta valves. I have been a cyclist for over 20 years. Mostly road bikes. One way I make sure I have proper air pressure is to remove most of the air from my tires after every ride. Pumping air before every ride insures I have the right pressure. Also not having over 100lbs of pressure in the tire before hand will I think solve the bad fit problems some are experiencing. When I start to pump air in I have only around 40-50 lbs of air in the tires. I have never experiaced any of the problems in some of the earlier reviews. I have been using this pump for 3+ years.
Works fine for me
My background: I just graduated from UMass, where I raced bicycles during mountain and road season, and lived with two bike mechanics. This pump is good. We had this pump at the shop, and at our house. I haven't had any serious issues with presta or schrader valves. The pump is solid, has good heft to it, and expels more air per pump than cheaper pumps I've had. There's no such thing as a universally perfect pump, so I think people need to be realistic about it, learn to use the pump they have, and get on the bike. All pumps have parts that go over time, this one seems like it'll out last many other models. It's entirely reliable and at this price point, I'm happy with it.
Joe Blow works for me
I've used a Joe Blow Sport for about 10 months to inflate the tires on my hybrid and other bikes up to 100 psi. I've been pleased with it and have had no problems with presta valves, either long or short, threaded or not. I've only used it on schraeder valves once or twice. It's cool that it comes with adapters for balls and other non-tire inflatables. I like the way the pump has clips to hold the adapters and hose. It seems a little hard to pump, but maybe that's just me. Also, on threaded valves I wonder if the threads will shred the pump head gasket over time. All in all, a good pump for me.
Great pump for the $$
REI has 10 kinds of pumps on shelf from cheap to super expensive, I did not want to spend $150 on a bike pump so I asked the repair tech inside the shop for a recommendation - they were using the Joe Blow every day so I figured if it was good enough for the shop, it was good enough for me. Excellent pump, very well made and its accurate. Only reason it did not get 5 stars is that the handles are plastic - not sure how long they will last if you use it a lot, but we'll see I guess. For the money, this is an excellent pump.
I bought this pump from REI well over 10 years ago (probably more like 20), and it's always been ready to go. I've pumped up bike tires, basketballs, soccer balls, hand truck tires, the tires on my van (that was work!), and who knows what else. Early on the hose cracked, and Topeak sent me a new one gratis. The rubber seal in the head that goes around the valve stem is finally wearing out, so it's started leaking a little. Turns out there's a rebuild kit from [@] for $4.95. When that gets here I guess I'll be good for another decade or so.
pump works great. its super easy to attatch to either type of valve and seal with out any leaks. super easy to pump, the presure gage is great and easy to see...has a movable dial on it so you can mark where you want the psi which makes it super easy to see and know when to stop. best pump i have used by far at this price point. Only reason i gave it 4 stars rather then 5 is because i have used higher end pumps that just felt better as far as ease of use however again, at this price point is great.
Works like any pump should
This is my primary pump that I use on all my bikes (mountain and road). I bought it about 6 months ago and I have no complaints. Works easily enough. Some pumps have more precise diles, but I never have any issue with getting the correct amount of air in it. I got it on sale, so for the amount I paid, I am certainly happy with it. The only thing that could be a bit better is its stability. You definitely have to keep your foot on it when you pump. But I guess you should on any pump.
