Topeak's fattest version in the RaceRocket® series this all-aluminum mountain pump gets big volume tires up to pressure fast.
This elegant little mini pump features a full aluminum body, head, and pump handle and is designed with an increased barrel diameter to push more air per stroke. An extendable hose with SmartHead® ThreadLock fills Presta and Schrader valves with ease and helps take the stress off the valve stem when filling the tire. Its efficient and smooth action inflates tires to 90 psi / 6 bar. Compact in size it easily fits in a jersey pocket or saddlebag and with a low weight of only 114 g the RaceRocket MT is never a burden to carry into the backwoods.
Note: Use the PCT Cap to tighten or remove two-piece Presta valve cores when necessary.

I don't have flats often thankfully but when it happens, you want to know your gear won't let you down.
I have owned this pump for over 3 years and used it on multiple occasions both for MTB and Road/Gravel, so I feel good about offering a legit review.
Two weeks ago I suffered a bad rear puncture (sharp rock) riding my road bike and had to stop b/c sealant was spraying all over the frame, seat, etc and tire deflated rather quickly.
Going about my pump usage, I see a pretty consistent problem with it and that is valve cores will get unscrewed when removing pump hose. This has occurred multiple times now using this pump on different valves, bikes, etc, and it's frustrating when this happens. I believe it's due to not having a relief valve near the hose end to release pressure in the pump's hose making the head's O-ring grip the Presta valve core too tightly.
The way I sort of resolved this was 1) ensure your Presta valve cores are very tight PRIOR to using pump, and 2) when removing the hose from the valve, try unscrewing pump head maybe 2-3 revolutions, and wiggle the hose adapter back and forth several times while listening for air burping past the valve (as you want to release hose pressure only, not deflate the tire again). It may take a few times to get this down by feel before you feel confident your valve core isn't coming out again.
During this flat, I had to inflate tire 3 times b/c the pump kept unscrewing my valve core making me frustrated as hands were getting cold and process was taking too long.
The pumps quality, fit, grippy handle, & solid design are all good though, but I would REALLY like to see a relief valve added to resolve this annoying issue. When using this pump, there's a good amount of air with every stroke so tire inflation is pretty quick for such a compact pump IMO.
I got this because my high pressure road hand pump just wears you out trying to inflate fat tires. Wanted to see if the high volume thing really made a difference. It does. The pump seems to be well made, the hose and connector work and the rubber handle feels nice in use. The attachment to the bike appears secure and works so far. Nice addition.
Have used it once since purchase. Was able to pump my 32 mm tubeless up to 60 psi. Liked the extending tube which prevents damaging the stem. Liked the ability to screw the pump head onto the valve stem.
