3.0 out of 5 stars.  Good product for experts, July 20, 2011
By Desert Bachelor (Phoenix, AZ)
This is a well-made pump that has a holder that fits rather cleverly underneath a standard water-bottle bracket. The rubber strap that holds it in place on the holder seems strong and yet has the necessary elasticity to hold its tautness for a long time. Unfortunately, I cannot imagine how the manufacturer concluded that there was no need for even the briefest of instructions: Most importantly, how to convert the tip from the default Presta valve use to what most people have known since they were kids (but didn't know the name), the Schrader valve. The pump came attached to a piece of cardboard, but the cardboard had not one sentence of instruction printed on it. I was so baffled as to how this pump works that I carried it on my bike for months just hoping I would never have to use it. I thought maybe it simply wasn't every going to work with my tires, but it was too late to return it. Finally after almost becoming stranded with an extremely low tire about five miles from home, when I got back I did a google search using a few key words, and came upon a review here that described it in words how to convert the tip. Then I found a video posted on Youtube that showed how. Now I know, but it shouldn't have taken an online internet search to figure it out. Shame on Topeak for assuming everyone is already an expert in their products.

5.0 out of 5 stars.  FYI shrader valves, December 18, 2010
By SF Mission
Unscrew the gray cap.
Pull out the black insert(s). There should be two pieces but you may have to pull them apart.
Take the one with the point end and push it through the small hole of the cylindrical one.
Put the pair back into the pump with the larger hole facing out.
Reattach the cap.

2.0 out of 5 stars.  Mixed feelings, mostly disappointed, July 15, 2011
By Chris (Columbus Ohio)
After reading reviews for this pump, I ordered it and received it a couple of days later. I will admit that after not biking for several (nearly 20) years, then getting back into it I was not used to Presta valves. My first attempt to top off my tire (it was about 5lbs under the desired pressure) left me with a blown tube. Examination revealed that a hole developed where the stem met the tube. After buying a replacement (and slightly heavier duty) tube I tried pumping that one up and received the same result. After getting it up to around 40 lbs of pressure, the new tube blew in the same way. I checked my rim to make sure there were no sharp burrs at the stem hole that would have caused the tube to rip or tear at the base of the stem, but there were none.

Based on what I saw, the one-piece design of the pump makes it very easy to cause a lot of wear and tear on the stem and tube as you pump. Granted, after realizing this and taking my time to pump up my tire carefully (a third time wiht another new tube) I got it up to pressure in about fifteen minutes of pumping and periodic checking. I'm more than willing to concede that my unfamiliarity with presta valves and newer tires has probably taught me a $20 lesson as well :)

Regardless, the pump is solid and well made. The mounting bracket coexists well with my water bottle bracket and the rubber strap holds it firmly in place. I'm a little sketchy about continuing to use the pump. I will keep it as an emergency backup (perhaps with my wife's bike as she has schrader valves), but have picked up a Topeak Turbo Morph Bike Pump with Gauge to use as my primary on the road pump. I figure a pump with a hose that I can clamp onto the stem will greatly reduce the chances of a repeat performance.

5.0 out of 5 stars.  Great cheap pump, July 18, 2011
By Paul
Pump works great. Inflates tires to a pretty high PSI and is pretty easy to pump. Having both Schrader & Presta valves is great. Even better, this pump is very light and attaches well to any bike frame. Definitely worth the money.

4.0 out of 5 stars.  Good value for the money, December 28, 2010
By Richard V Franzen
Well constructed; I've used it a few times when having flats, and it works well. As with any small pump you have to use a lot of effort, but it seems well built and attaches to my MTB frame nicely. The pump also seems to stay in place well, and doesn't come loose on bumps, or have the handle come out to full extended position either accidentally.

5.0 out of 5 stars.  Great pump I own 2 of them now..., July 25, 2011
By Jay Baker (Florida, USA)
I ordered one of these for my mountain bike after the one that was on it got messed up. Liked it so much that I ended up buying another one for a touring bike I'm setting up. It is small but seems to fill the mountain bike tire up to 45psi pretty quickly. Haven't tried to fully air the tires on my road bike yet... to 100psi.

5.0 out of 5 stars.  Great, July 24, 2011
By T. Nech (Seattle, WA)
After I found out how to use this on schrader valves, it works flawlessly on all of my bikes. My only wish is that the frame mount didn't require braze-ons, since my main ride doesn't have any.

5.0 out of 5 stars.  Pocket Rocket, July 11, 2011
By trazz4
This is a great little pump, used it out of the box to inflate a mountain bike tire, 26x2.0 schrader valve no problems. Pump does get a little warm, attaches nicely to the frame from underneath the water bottle cage, hardware is included, or small enough to go in your pack depending on the length of your ride. Don't get rid of your floor pump at home, but nice to know this pump can be depended on out on the trail. This is a must have for me and I'm very happy with this purchase. Shipping was fast also. A+

4.0 out of 5 stars.  Smaller than I expected, July 6, 2011
By Jed (New York City, NY)
Maybe it's unfair for me to write this review and say this is smaller than I expected. The pump works fine and is very nice but it doesn't push a lot of air at once so it take a bit of work. My original pump was a little bigger, pumped whether I pushed or pulled, the handle was a tool for removing the tire off the rim, and also had a patch kit in the handle. That one broke and I bought this one because of the reviews. The pump works, and it's very light, but it will take some work to inflate your tire.

4.0 out of 5 stars.  Make sure you have a ROAD bike; won't do for mountain or hybrid, November 13, 2011
By Robert Wolfe (Chicago, IL United States)
Very good pump for a road bike tire which has relatively small volume of air, but if you have a MOUNTAIN or HYBRID you should get the Topeak Road Morph G Bike Pump with Gauge, otherwise you will weary yourself trying to air into your tire. The extra few $$ will be well worth the cost and save your arms from fatigue, your brain from frustration, and your knuckles from cuts and bruises.

The only thing that it is lacking is a pressure gauge.

5.0 out of 5 stars.  Super lightweight, October 11, 2011
By The Scout
It works well, and will get you out of a pinch (especially with mtb tires), but holy cow, this thing is light! The overall construction is good, and I would expect it to be a little fragile for the weight. The mount works great (under the bottle cage mount), and it has yet to fall out of the mount when doing some ROCKY mountain biking. This is a great pump!

5.0 out of 5 stars.  Nice little pump!!!, October 6, 2011
By dvsdubdub (Utah)
This is a very nice little pump. Does exactly what its supposed to do. You do need to unscrew the end of it and change the inside parts around depending on which type of valve you have. Its easy though. After receiving it I let some of the air out of my tire so that I could use this pump to put air in my tire. It worked great, my tire was fully inflated in about 15 seconds. I am glad to know I have this pump if I ever need it and I know someday I will. A must have for any avid bike rider! Highly recommend! Thanks for reading.

Attractive aluminum body, feels sturdy in the hand, and I had no problem attaching it to my Schrader valves and pumping to 50 PSI. Gets a bit warm to the touch after use, but nothing unbearable. Highly recommended.

1.0 out of 5 stars.  wrong product? Or mislabeled product?, November 1, 2011
By disappointed mike
All I have to say is that when a pump says it pumps bike tires, then it should probably pump bike tires. I have a normal bicycle, and this pump won't pump up the tires. Also, the little instruction picture does NOT match what the pump's mechanical pieces actually look like, so its pretty hard to decipher exactly how this thing was meant to work on different tire types. Well, don't buy. Buy a different pump instead, this one is junk...

5.0 out of 5 stars.  Love it!, August 27, 2011
By Monique Gray
Took a minute to figure out how to use it! Once I learned that the rubber thing came off and that I had to flip the parts on the inside around. It came set up to use on another tire. Once I got it set up to use on mine, it pumped up my tires! And I love that it hooks to my bike so I can use it on rides. I love this little thing. It takes a lot of pumps to pump up my tires, but it's really easy to use. It's not hard to move the pump at all. I'm glad I purchased it and would recommend it to anyone.

5.0 out of 5 stars.  Great buy...Great pump!!!, September 11, 2011
By T. Seales (Philadelphia, PA United States)
Was looking for a small pump that I can go anywhere I ride and because of the great reviews by other buyers I got one. I am new to bike riding so I was a little confused on how to use the pump (for some reason I did not notice the instructions with my packaging at all) but thankfully one of the buyers posted pictures with a instructions on how to use it. Had to unscrew the cap/base and remove the piece inside (did not realize that it was actually two pieces,I have to admit I feel somewhat slow for not noticing the obvious). All I had to do was rearrange these two inside pieces for them to fit my tube valve. Once this was all sorted out I used it to pump air in my tires which were a little soft because my bike has been sitting there for a couple months. I have to say it probably took less that ten easy, quick pumps for my tires get to the firmness that I like.

4.0 out of 5 stars.  pocket rockettt!, September 7, 2011
By Fiendship Fun (MD, USA)
the instructions on the packaging were a bit ambiguous- when i first got it i thought i bought the wrong bike pump because the adapter was for a smaller fitting valve. there is a diagram on the front which i thought was design first. i reread the description and there is no word about it. so i took a toothpick and yanked out the adapter to realize you're supposed to flip the little gadgets inside over for two different types of valves- very clever! fits perfectly next to the bottle rack.

anywho- i think this little thing packs a lot of power. i didn't feel like i had to use too much elbow grease to get my flat tires inflated.

4.0 out of 5 stars.  Outstanding for a small, convenient pump, September 5, 2011
By Charles C. Hardin
This pump is amazingly easy to mount to a bike with braze-ons, and convenient to use. Its usefulness is mostly restricted to small, incremental tire inflation. If you try to pump a tire up from zero with this thing, you have a lot of work ahead of you. However, that is what floor pumps are for. A road pump like this is useful for dealing with a quick top-off of tire pressure, and as long as you use it for that, it will give good service.

4.0 out of 5 stars.  Works perfectly... once you figure out how to use it., September 28, 2011
By D. Gutierrez (USA)
So I got my new pump and was all excited to mount it on my bike and use it. I let a bit of air out of my tire and went to connect the pump to the valve stem... No go. Didn't create a seal. The pump head didn't seem to be wide enough to "go around" the whole valve... Hmm..

So I check the VERY sparse directions, which are actually not directions at all, but semi-vague diagrams that only become clear after you understand what they mean.

From the look of the diagrams, I had to open the pump head and flip this little plastic piece around. No go. Still nothing...

Then I went to the Topeak website and checked out the video they have posted. [...] Mystery solved. The plastic piece comes apart, at which point you turn the two halves around and plug them into each other - poof! Like magic, it fits and my tire is inflated again.

Haven't used this on the road yet, but it certainly re-inflated my tire with no problems. The only reason I rated this 4 stars instead of 5 is that if you are not a bike aficionado, you might not know about different valve types (I didn't) and not realize that the plastic piece comes apart. Basically, poor directions. But the product seems solid and functions as it should.

NOTE: In the video the two halves of the plastic piece are different colors (one red, one black) -- mine were both black, so it was not easy to see that it comes apart.

Will update this review if I run into any problems.

5.0 out of 5 stars.  Lightweight & very useful, September 23, 2011
By Chance Evans
I've owned this product since Aug 2010, and it's been attached to my bike ever since. It wasn't until a few weeks ago that I actually got to use it 'for real'. I was a few miles from my home when I noticed my back tire was going flat. I changed the tube out on the side of the road, and used this little jewel to air up the replacement. It takes a little while to air up the tire, but wasn't bad. It's better than the alternative. I would highly recommend this product for anyone looking to carry an air pump while on the road. The build is sturdy, and it's very light.

4.0 out of 5 stars.  Great pump for me, September 21, 2011

I was able to inflate my two children bike tires with no effort, for the heck of it I tried it on my car tires for a couple of PSIs only it can inflate those high pressure bike tires) and to my surprise it did get them to the right PSI it took some pumping but the pump handled it. The size and convenience of tucking it anywhere in the car or in a backpack can't be beat.

5.0 out of 5 stars.  Great!, September 18, 2011
By Allan Limbo (California, USA)
Pros:
-I'm glad I carry this around when I bike. Two weeks ago, during the night-time, I had a flat tire from running over a nail. I patched my tubing & used the Pocket Rocket to pump my tubing. It's convenient since it is very small & light-weight; you can either attach it to your bike or carry it along.

Cons:
-I wish that it displayed how much pressure that you are pumping into the tubing. It can really do harm if someone were to unintentionally over-inflate it.

Overall:
-Five stars! Great product! I hope they add some sort of pressure-gauge in the future.

5.0 out of 5 stars.  Bike pump review, November 25, 2011
By Leroy
I've had this pump for about a year, or perhaps more relevantly, ~10 flats, now. This has been a very dependable part of my biking kit. After fixing a flat, it shouldn't take more than 2 minutes of pumping to get a tube reflated to a decent (~80) psi. Comes with equipment to attach it to your bike, but recently I've been keeping it in my backpack since I sometimes take different bikes.

I haven't had to try to reinflate a schrader valve with this yet, but it looks like a simple procedure. The front unscrews, and you switch the valve around.

And if you're using this pump as your primary pump, you're doing it wrong (or really stingy). This doesn't have a gauge, and you won't be able to get into the 100+psi range easily.

4.0 out of 5 stars.  Could have better directions, November 18, 2011
By Pileosnafu (Orlando)
Other then having directions that assume you can read hieroglyphs this is awesome. I uploaded some pictures on the 3 steps to convert to a Schrader Valve. The directions do not make it clear that the plastic part comes apart.
As others have said it does get warm but that is just what happens when you compress air, so its to be expected, the small lightweight pump doesn't leave much room for insulation.

5.0 out of 5 stars.  Lightweight Lifesaver, November 11, 2011
By Namaste
I had never used a small pump like this before and since I've started putting on the miles realized one of these might be necessary in the future. It's great! Made of a lightweight material with an adapter for either valve type(schrader/presta), this thing gets the job done. No, it's not made to be your only pump as it provides a low volume of air, but in case of emergency, this thing is your lifesaver. My only criticism is the rubber cap that encloses the air tip because it basically serves no purpose since it never stays closed. I've tried closing it into the presta and schrader adapter and no luck. Otherwise, the handle locks in when not in use and the strap keeps it secure on the bike to the bottle mount. I often don't even realize it's there! Great product!

By JG (Orange County)
All hand pumps take a little work to pump up a tire after a flat or even to top off. But this will get your tire enough pressure to get you home or to finish your ride. Not a replacement for a floor pump but it can get close while on a ride. Use it to fill your tube after a flat and then top off with CO2.

5.0 out of 5 stars.  Solid Product, October 24, 2011
By JustinL
I purchased the Topeak Pocket Rocket Master Blaster (what a name, huh?!) from Amazon after reading reviews for a number of portable bike pumps available on the site. Upon initial inspection, it really looks like a well-constructed product. The aluminum body is quite light, seems durable and the silver color shouldn't have a problem coordinating with really any color scheme. The valve stem locking mechanism seems solid, too.
The multiple valve options (Schraeder/Presta/Dunlop) definitely are a nice touch. I've just started getting into road biking - my gf picked me up a '73 Schwinn Varsity from a yard sale - and the tubes in it use Schraeder valves. I assume I'll upgrade bikes/wheels/tubes at some point along the road (no pun intended), and didn't want to have to needlessly spend money on a different pump if different tubes are purchased. You'll need to do some adjustments with the plastic bits inside the head to switch between the 3, but that didn't take more than a couple minutes of adjusting around to figure out.
As other reviewers have stated, this isn't aimed at being your primary bike pump (the small canister obviously lacks the capacity of a standing pump or air compressor), but if you're out biking and get a flat, this works exactly as it should. The only feature I can think of that could make it better would be a small pressure gauge, but that's just being nit picky. Any rider should be able to use this to pump their tire to adequate riding pressure with ease, at the very least until they're able to find a higher capacity, higher speed pump.
I ordered this with a couple other items that qualified for free super-saver shipping. Shipping took just shy of 2 weeks, which was a bit of a let down since bike-riding season is quickly coming to a close. It was, however, a nice surprise when the items arrived at my doorstep, as the tracking number I was given had not even been updated beyond "we have received notice to expect this shipment..." by the time it arrived. But that's more a review of USPS than the product lol.

5.0 out of 5 stars.  One Of The Better Frame Pumps, December 1, 2011
By My Dogs Are The Finest People I .. (Rural Kentucky)
As others have already stated, this is a good pump that is light and works well. It is constructed much better than most other pumps in this price range- and by far has the best-made head, which will not damage your presta valves. I had initially purchased a Bell frame pump, on impulse at a B&M....what a mistake that was! All air pumps are not created equal! This Topeak pump actually works and works well. Although it is not a double-action pump (It only produces air on the down-stroke) it still inflates the tires quite quickly, and as stated before, does not damage your presta valves. It's a good deal for the price- a quality pump that will not let you down.

I have been using this pump for about 6 months and have found that it performs flawlessly.

3.0 out of 5 stars.  Works in a pinch, needs muscle., November 26, 2011
By Terran Wheeling
Meh.

It's okay. Works great for emergencies and wider tires. Sure, specs say up to 160 psi, but who are we fooling here? After 80 psi you better be really strong. My biggest problem with this is the higher psi you approach it gets awkward/difficult to operate. In an emergency, on a road bike, it will get your tire inflated enough to ride to a floor pump, but don't rely on it as a primary pump or even to 'top off' your pressure.

I'm glad mine got stolen. It gave me the "opportunity" to purchase a Lezyne micro floor pump, which is 3x more expensive, but 3x more worth it, and 3x more likely to get stolen. D'oh.
