Topeak Mountain TT Twin Turbo 120psi/8.3bar Pump

Bought this to carry on my dual sport motorcycle. Second ride after I added it to my tool kit I picked up a nail and had to repair the rear tube on the side of the road. Its not super fast but it does inflate on both the push & pull stroke. Nice because its small and light so its a valuable piece of kit for the bike.

A quick and powerful non-nonsense portable air pump with TOPEAK quality, which never disappoints. Keep in mind that this pump is quite large, not one that I would attach to the bike or carry all the time. It's more for long/remote trips with a backpack, riding surfaces where the likelihood of a puncture is higher and more consequential.

I was with some friends riding trails and one of them had low air. we didn't have a pump so we asked someone riding by if they had one and they did. It was a tiny little hand pump and it actually let more air out than actually pump up the tire. so we said thank you and we were just about to go back to the car to get a floor pump until another rider came along and said he had a good hand pump. we were skeptical. he busted it out and the first thing I noticed was it was bigger than the other pump we just tried to use. His was the twin turbo pump and WOW. This little pump had our tire pumped solid in about 2 minutes or less. I asked the guy if I could take a picture of it so I could buy one off amazon when I got home. sure enough I did and Im glad I did. Best hand pump I've ever used.

It is difficult to change the insides to fit a preset valve. Hopefully you have a multi tool with pliers on it to remove and flip the rubber parts inside.

I've used Topeak pumps with my mountain bike tires. And whether it's tubes or tubeless, Topeak has worked well for me. Catch it sale and it's a good deal. No complaints, pretty sturdy for my needs.

Something’s you hope that you never need. But sadly we did and this one worked well. Expect to take some time as it is not a very big air chamber but it got the job done. If it would be larger we may not have had it along but this fits well into our bike bag and it is there if you need it.

I ordered this pump based on a review I read in a cycling magazine. They ranked it #1 of the pumps they tested. When I received it, I was immediately confused by the way it operates this pump inhales on the pull stroke and exhaled on the push stroke. So it takes air out of the tire and puts it back in at higher pressure. So far I have not been successful at getting much pressure into a tire. I am keeping it because it will serve its purpose in an emergency but no where near full pressure. It came set up for Schrader valves and I needed to switch it to presta. There is no explanation of how to do this. Pure trial and error. Its not all bad though. It is made of very high grade materials and it mounts very well to a bottle frame mount. I gave it three stars.

This pump was purchased so that I could adjust tire pressure on my Fat Bike while on a ride. I have a smaller pump that works on my smaller MTB tires which are 27.5 x 2.6 and 2.5 front and rear respectively, but using it on a 26 x 4.8...it just doesn't have the stroke volume for that much tire. This pump made easy work of increasing tire pressure on the fat bike and even easier inflation of the MTB tires that I mentioned as well. It's not the smallest pump on the market, but as I found out the hard way, the smallest form factor doesn't always result in the performance you actually need.
