I like the big gauge that only goes to 40psi. It’s very easy to be accurate with the pressure, hit 20 psi exactly with this pump unlike using a road bike pump. Also pumps quickly.

Muy buen producto, sirve para ambos tipos de válvulas. Se inflan las llantas muy rápido y sin mayor esfuerzo.

Buen producto

Very accurate PSI, great engagement on presta valve

Worst gauge on the planet. If I wanted something to just fill air I’d shop at Walmart. This product is worse, the gauge is useless. Customer service was like, yeah, that’s too bad. Wow ok, thanks for nothing! Don’t buy this

I love everything about this pump except it's inaccurate gauge. The gauge is highly inaccurate and therefore useless. The gauge on my pump is off by at least 5 pounds, resulting in the pump being useless to me and a total waste of my money.

I love how the pump functions and the gauge range would have been perfect, I loved the idea of having 0 to 40 psi over such a wide spread on the gauge, would have made it easy to read. But like another comment I saw, my gauge is probably off by about 15 psi or more. Hard to understand how such a big error can be allowed to pass through the system.

I didn't have an immediate need after I purchased it but was itching to test it out. I tried filling up my sports car's 335 wide tires and it freaking works! Takes about 2 pumps per psi or so. For a mountain bike this is gonna be amazing! I can't wait to knock tubeless beads into the side of my rim with over half a liter per pump without having to kick on a compressor!

Total bummer. It's a fancy pump and well built... except for the air pressure gauge. I used this frequently for about 60 days. It has smooth action and the nozzle is great. Doesn't leak any air. HOWEVER... the large fancy gauge is inaccurate. Real Pressure: 10 Psi -- Reading 1psi /// Real Pressure: 25 psi -- Reading 20 psi /// Real Pressure: 34 psi -- Reading 30 psi /// I bought this assuming the large gauge, which is easy to read, would tell accurate pressures. I check this with a two different detail gauges & another pump. This pump tells wrong air pressures.

Heavy but very nice. Hose is long and gauge seems to be within 2psi.

Great pump!!

Works great. My old tired eyes can read the gauge without any problem. Takes only a few pumps to get the tires up to pressure.

Setting up tubeless effortless. High volume let you easily add pressure to high volume MTB tires with only two or three strokes. Very sturdy construction. I am happy with my purchase.

Works as described

the pump is of high quality, robust and easy to use

This thing is awesome. You can read the pressures easily for MTBs. Release air from the handle. I wish i would have known it existed a long time ago.

Works great and pumps a large volume of air.

This pump is only for lower pressure tires. But man does it put out the air when you use it. Pumped up my Mt. Bike tires quickly and efficiently. Way better than the PARK TOOLS pump I had before this one. Guage is large number and easy to read.

El producto que buscaba. Excelente.

I really like this pump. It's perfect for mountain bike tires with a large accurate pressure gauge and simple pressure release on the handle. Also it's very easy to connect to the tire valve.

Un caño, fundamental para cada salida chequear la presión de las ruedas.

Very accurate and moves a large volume air. Pumping up has never been easier or more reliable.

This pump is perfect for mountain bike tires. I can easily read the gauge in 1/2 lb increments.

este bomba se puede utilizar para llanta de ruta? y que medida de aire seria?

Awesome pump. Barely have to pump to get my tires to pressure. I check my tires every ride and this pump, with it's huge volume barrel and big dial, make it a super quick task before I head out. Super accurate too, matches right up to my Topeak D2X digital gauge. Haven't tried seating a bead yet but pretty certain it will be a non issue.

Definitely does as advertised. Pressure reads right and it pumps quick enough to get job done

Sturdy and works well

after being delivered my order was stolen from my door specialize sent a replacement pump within days with no questions asked...will buy all my biking equipment from them from know on...

Amazing high volume floor pump for MTB tires! This pump does a fantastic job of inflating high volume tires. I get approximately 10PSI of air per pump for 29er mountain bike tires between 2.3 and 2.6 inches. The analog guage is surprisingly accurate as well. Easily within one PSI or less to what my accurate digital gauge shows. I'm able to seat mountain bike tires tubeless with this pump easily without using a boost pump or compressor.

Works great for setting MTB tires. Really surprised.

Cannot say enough about how good this floor pump is. I just purchased my second one as I live in Connecticut and also spend family time in Maine and cannot live without one close by. The volume is very good with excellent gauge resolution and an innovative bleeder on the T handle. I have had absolutely no issues with these floor pumps. Between my mountain ( Enduro and DH) and fat tire bikes, it provides accurate low pressure ranges for tubeless and tubed tires.

I purchased this pump to replace my old yellow Specialized pump. I bought that yellow pump back 2004 from the Super Go bike store in Tucson. It has pumped up 100's of bike tires, our ATV's, several car tires and my daughter used it regularly to air up her leaking Tacoma tire for about a year. I have taken it apart and cleaned it a few times finally wore the O-rings out. So far I have not found replacement O-rings. It would be great if Specialized had an rebuild O-ring kit for these pumps. If they do I have yet to it. That aside, these pumps are made to last and all they need is a drop or two of oil every now and then.

Great low pressure pump. Very accurate readings for mountain bikes. Works excellent. Very happy with this product.

I used think pumping my tires was a chore now it's my favorite part of the day!

My regular floor pump is great for road bikes, car tires, etc., but would not register pressure in the 20 psi range. This Specialized pump works great for correct pressure needed in MTB tires. I needed to order online, since my bike shop did not carry. Online ordering was easy. Specialized Customer Service was excellent! Definitely recommended.
