Peak DX II Mini Pump, SmartHead Presta/Schrader, 90 PSI, Silver

Product has been improved in many ways since I bought my first one years ago. It is easier to switch between tire types, and product feels sturdier.Am pleased.

Bought this for a second bike I recently purchased. Leverage is a bit tricky but that is to expected for such a small sized pump. It gets the job done in an emergency!

This is a light weight, compact and a strong rescue bike pump that supports both types of tyre valve. It comes with the required bike mount.

Works fine and it's durable, pumps my road bike tires to a 100lbs with no problems.

I believe the unit was defective, as what should have been a one-way valve (the heart of any piston-operated pump) was clearly not working. I returned it (props to Amazon for making this very easy), and I'll eventually buy another brand of compact pump. For now I'm back to my (Topeak!) full-size frame pump, which is large (that's kind of the point) but always works when I need it.

NOTE: The 120psi rating on this product is not correct. It is rated for 90psi.I will say that I usually research my gear pretty thoroughly before purchasing. I was surprised to find this product rated moderately or poorly on other sites and highly here but I decided to take the plunge anyways.The first pump I received was defective and had a bad seal, so it was worthless out of the box. Thankfully Amazon has great customer service and shipped a new one out immediately which worked great. Other reviews warn that this pump may fail sometime in the near future so we'll see...The build quality is solid and I had no problems achieving a good seal on presta valves. I intend to use this for both mountain and road biking. On a set of 700x23 road bike tires I was able to achieve 85psi with moderate effort, so it appears the 90psi rating is spot on. It's not enough to act as a standalone pump for a multi-day ride but it is enough to get you home on a shorter trip (or to a shop who can inflate your tire fully).

I really like this pump for a Schrader valve (did not try it on a presta valve). It is supposed to work on both types. It fits fairly tight on the Schrader valve, but not so tight that the valve pushes into the rim. Before, I had a Topeak Mini Morph Bike Pump that gave me fits because it was so tight that the valve would push in and not engage the pin so it would not pump up the tube. That one I took back to the store (it was probably a manufacturing defect). I've only used it on my mountain bike and I get good pressure in my tube. The only thing I didn't care for was the side mounting bracket that fits under the water bottle. Instead, I used a front mounting bracket that keeps the pump in line with the down tube. But that is just my preference. I bought this at REI for $19.

Bought this first at REI and it was so good I had to buy another.

This is a great pump. When ever I use it there are envious looks as the ergo hand piece turns out 90 degrees to give a better position for pumping up the tires. It is a very effective pump and the second one I have purchased as bought one for hubby as well.

El paquete llegó mucho antes de lo esperado y en buenas condiciones. Elegí esta bomba porque ya la había ocupado en varias, pero no era mía. Es fácil de utilizar, ergonómica y compacta, por lo que si llevas una mochila pequeña fácilmente puedes transportala contigo; el material es de buena calidad (aluminio en su mayoría) y la agarradera también tiene plástico tipo silicón que evita que se resbale la mano.

Auch wenn Sie nicht ganz billig sind: Ich würde nie mehr etwas anderes als die Topeak Pumpen kaufen. Ich habe sie in allen möglichen Größen und auch schon mehrmals mit gutem Feedback verschenkt und weiterempfohlen. Der Aufsatz kommt mit allen Ventilen zurecht, wichtig, wenn man mit mehreren unterwegs ist und nicht jeder sein eigenes Werkzeug mitschleppen will.Die Verarbeitung ist dem Preis entsprechend einwandfrei.

I bought this pump to replace my previous Topeak pump. A copy of my original. Unfortunately is broke on its first use. The quality of this pump doesn't match my original. (make your own mind up on that). I wouldn't recommend this pump!

La calidad del producto es buena, sin embargo cuando intenté inflar una llanta de bicicleta, la sujeción de la bomba se perdía y no termin, en ningún intento por llenarla por completo.
