TopeakRaceRocket MT Hand Pump(Return to Product Page)

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.

Use it mostly on my gravel bike. Mount is secure even on rough roads. Compact enough for how much power you can get out of it. Inflates the low pressure tires really well.

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.

Works great. Black matches all bike colors. I carry one of these on both my gravel and MTB
